• sur 3liz: Sortie de Lizmap Web Client 3.7

  Publié: 29 January 2024, 12:00pm CET

  Lizmap Web Client 3.7

  Nous sommes heureux d'annoncer la sortie de Lizmap Web Client 3.7, la nouvelle version majeure de l'application.

  Financeurs

  • Geolab.re
  • Parc naturel régional du Haut-Jura
  • Portes du Soleil
  • SDEC Energie
  • Tenergie
  • Terre de Provence Agglomération
  • Vaucluse province in France
  • WPD

  Pré-requis et installation

  Il est désormais requis d'avoir un QGIS serveur minimum 3.22. Cependant, nous recommandons fortement d'utiliser une version LTR plus récente, comme la version 3.28 ou bien même la prochaine version LTR 3.34. Consultez la feuille de route QGIS.

  Pour utiliser pleinement de cette version 3.7, n'oubliez pas de mettre à jour votre extension Lizmap dans QGIS bureautique. Nous avons écrit un article dédié sur cette nouvelle version.

  Fonctionnalités Refonte du thème par défaut

  Un nouveau thème est disponible, apportant une interface utilisateur plus à jour. Il est désormais également plus facile de mettre à jour ces couleurs, car cela a été centralisé en utilisant seulement quelques variables CSS.

  

  Dataviz

  Dans l'extension, vous pouvez trouver de nouveaux paramètres pour chaque graphique. Par exemple, il est possible de définir deux titres différents, selon l'endroit où le graphique est affiché : soit dans le panneau principal de visualisation de données, soit dans une popup.

  La principale nouvelle fonctionnalité est la mise en page par Glisser&Déposer. Nous nous sommes inspirés de la fonctionnalité native de QGIS concernant la Mise en page du formulaire Glisser-Déposer. Dans Lizmap, lorsque vous avez de nombreux graphiques à afficher, vous pouvez les organiser en onglets ou conteneurs.

  Dans QGIS, voici un exemple de mise en page des graphiques :

  

  et voici le résultat dans Lizmap Web Client :

  

  Ces nouvelles fonctionnalités ont été financées par DDTM 34.

  Légende

  C'est l'une des fonctionnalités les plus visibles et attendues de Lizmap, il est possible de cocher/décocher les éléments de la légende individuellement.

  Nous avons également revu la façon dont Lizmap gérait les couches de base dans le projet (fonds de carte). Les utilisateurs sont désormais invités à utiliser le groupe baselayers dans la légende pour définir les couches de base. À l'aide d'une version à jour de l'extension, vous pouvez utiliser l'onglet "Fonds" pour vous aider.

  Nous avons également décidé d'utiliser le même comportement que dans QGIS Bureautique concernant la manière dont les utilisateurs manipulent la légende. Désormais, lors de l'activation d'un groupe, toutes les couches incluses dans ce groupe ne seront pas activées automatiquement.

  

  Pour inclure ces nouvelles fonctionnalités, beaucoup de re-factorisation du code Javascript ont été réalisées sous le capot, financées par le département du Calvados et Le Grand Narbonne.

  Mise en page

  Dans l'extension, un nouveau panneau sur les mises en page a été ajouté. Vous êtes invités à jeter un œil à ces nouveaux paramètres. Il est possible de :

  • définir par mise en page si nous l'activons ou non sur l'interface Web. Avant, il était seulement possible de choisir d'activer ou non l'impression à l'échelle des propriétés du projet
  • définir les groupes Lizmap qui sont autorisés à accéder à chaque mise en page
  • définir une icône personnalisée lorsque la mise en page est basée sur un atlas.
  • réduire le nombre de formats disponibles. Plus besoin de Javascript pour avoir une interface simplifiée
  • ...

  

  Ces nouvelles fonctionnalités ont été financées par DDTM 34.

  Au cours de ce travail, nous avons déprécié l'extension QGIS serveur AtlasPrint. Lizmap utilise désormais la fonctionnalité native de QGIS Serveur pour exporter en PDF un élément de l'atlas.

  Edition WebDAV

  Faunalia a contribué directement au code source de Lizmap en ajoutant le support WebDAV dans le formulaire d'édition lorsque l'outil d'édition a été défini sur stockage WebDAV. Vous pouvez consulter la documentation en ligne. Cela fonctionne également lors de l'affichage de la popup.

  Relations entre les tables

  Le support des relations 1-n entre tables a été amélioré lors de l'édition de ces couches :

  • Ajout d'une nouvelle entité "enfant" depuis la popup d'un parent
  • Affichage du tableau des entités "enfants" depuis le formulaire d'édition d'un parent

  

  

  Ces améliorations des relations 1-n ont été financées à la fois par la ville d'Avignon et Valabre.

  Dessin Texte et mesure

  Il est possible d'annoter la carte avec du texte dans l'outil de dessin. Les mesures ont également été améliorées.

  

  Ces fonctionnalités ont été financées par le Territoire de Belfort et Lons-le-Saunier.

  Contraintes

  Lors du dessin de certaines géométries sur Lizmap, vous pouvez désormais définir une contrainte de longueur et/ou d'angle.

  

  Action

  De nouveaux "contextes" ont été ajoutés à la fonctionnalité Actions. Avant, les actions n'étaient disponibles que pour le contexte d'entité. Avec la version 3.7, les actions peuvent être définies dans le contexte couche (similaire à la fonctionnalité native de QGIS) ou même au niveau duprojet.

  

  Ces nouveautés ont été financées par Porte du Soleil.

  Javascript

  En raison du travail qui a été effectué lors de la légende ou d'autres fonctionnalités de Lizmap, certains scripts Javascript précédents pourraient ne plus fonctionner et devront être adaptés.

  Bonne nouvelle, certains de ces anciens scripts pourraient ne plus être nécessaires. Par exemple, à propos de la légende, vous êtes invités à passer au thème QGIS natif.

  Téléchargement

  Vous pouvez télécharger le dernier zip sur notre page des sorties.

  Vous pouvez également consulter la liste des modifications complètes ("changelog") de la version 3.7.0, en anglais.

  Modules

  À la date du 29 janvier 2024, voici la liste des modules qui ont été mis à jour pour 3.7 :

  • MapBuilder
  • PgRouting
  • PgMetadata
  • Adresse ??
  • Cadastre ??

• sur 3liz: Release of Lizmap Web Client 3.7

  Publié: 29 January 2024, 12:00pm CET

  Lizmap Web Client 3.7

  3Liz is pleased to announce the release of Lizmap Web Client 3.7, the new major version of the application.

  Funders

  • Geolab.re
  • Parc naturel régional du Haut-Jura
  • Portes du Soleil
  • SDEC Energie
  • Tenergie
  • Terre de Provence Agglomération
  • Vaucluse province in France
  • WPD

  Pre-requirements and installation

  It is now required to have a minimum QGIS server 3.22. However, we highly recommend using the latest LTR version, i.e. version 3.28 or even soon the next LTR version 3.34. Check the QGIS roadmap.

  To take full advantage of this version 3.7, don't forget to update your Lizmap plugin in QGIS desktop. We've written an article dedicated to this new version.

  Features Overhaul of the default theme

  A new theme is available, bringing a more up-to-date UI. It's now also easier to update these colors, because it has been centralized using just a few CSS variables.

  

  Dataviz

  In the plugin, you can find new settings about each plot. For instance, it's possible to set two different titles, depending on where the plot is displayed : either in the main dataviz panel or within a popup.

  The main new feature is the Drag&Drop layout. We have been inspired by the native feature in QGIS about the Drag&Drop form layout. In Lizmap, when you have many plots to display, you can organize them in tabs or containers.

  In QGIS, this is an example of the layout :

  

  and the result in Lizmap Web Client :

  

  These new features have been funded by DDTM 34.

  Legend

  This is one of the most visible and expected feature in Lizmap, it's possible to check/uncheck the legend items individually.

  We also reviewed the way Lizmap was managing base layers in the project. Users are now invited to use the baselayers group in the legend to define your base layers. With an updated version of the plugin, use the "Baselayers" tab to help you.

  We also decided to stick to the same behavior as in QGIS Desktop on how users are manipulating the legend. Now, when enabling a group, it will not toggle "ON" all layers included within this group.

  

  To include these new features, a lot of Javascript refactoring has been done under the hood, funded by both Calvados province and Le Grand Narbonne.

  Layouts

  In the plugin, a new panel about layouts landed. You are invited to have a look to these new settings. It's possible to :

  • set per layout if we enable it or not on the web interface. Before, it was only possible to choose to enable or not printing capabilities at the project level.
  • define Lizmap groups which are allowed to access this layout
  • define a custom icon when the layout is based on an atlas.
  • reduce the number of formats available. No more Javascript needed to have a simplified interface
  • ...

  

  These new features have been funded by DDTM 34.

  During this work, we deprecated the QGIS server plugin AtlasPrint. Lizmap now uses the native feature from QGIS Server for printing an atlas feature.

  Editing WebDAV

  Faunalia contributed directly on the Lizmap source code by adding WebDAV support in form when the editing widget has been set to WebDAV storage, check the online documentation. It works as well when displaying the popup.

  Relations between tables

  The support of relations 1-n between tables has been improved when editing these layers :

  • Adding new "child" features from the popup of a parent
  • Displaying the table of "child" features from the editing form of a parent

  

  

  These improvements about relations 1-n were funded by both Avignon city and Valabre.

  Drawing Text and measures

  It's possible to annotate the map with some text in the drawing tool. Measures have been improved as well.

  

  These features were funded by Territoire de Belfort and Lons-le-Saunier.

  Constraints

  When digitizing some geometries on Lizmap, you can now set some length and/or angle constraints.

  

  Actions

  Some new scopes have been added the Actions feature. Before, it was only the feature scope. With 3.7, Actions can be defined in the layer scope or (similar to QGIS native actions feature) or even in the project scope.

  

  These new features have been funded by Porte du Soleil.

  Javascript

  Due to the work which have been done during the legend or other features in Lizmap, some previous Javascript script might not work anymore and need to be adapted.

  Good news, some of these legacy scripts might not be needed anymore. For instance, about the legend, you are invited to switch to the native QGIS theme feature.

  Download

  You can download the latest zip on our releases page.

  You can also check the full changelog of version 3.7.0.

  Modules

  As of January 29rd 2024, this is the list of modules which have been released for 3.7 :

  • MapBuilder
  • PgRouting
  • PgMetadata
  • Adresse ??
  • Cadastre ??
  • NetADS ??
  • SAML authentication

  Other modules are work-in-progress.

  We hope you will enjoy this new version ?

• sur Free and Open Source GIS Ramblings: Trajectools update: stop detection & trajectory styling

  Publié: 27 January 2024, 2:38pm CET

  The Trajectools toolbox has continued growing:

  

  I’m continuously testing the algorithms integrated so far to see if they work as GIS users would expect and can to ensure that they can be integrated in Processing model seamlessly.

  Because naming things is tricky, I’m currently struggling with how to best group the toolbox algorithms into meaningful categories. I looked into the categories mentioned in OGC Moving Features Access but honestly found them kind of lacking:

  

  Andrienko et al.’s book “Visual Analytics of Movement” comes closer to what I’m looking for:

  

  … but I’m not convinced yet. So take the above listed three categories with a grain of salt. Those may change before the release. (Any inputs / feedback / recommendation welcome!)

  Let me close this quick status update with a screencast showcasing stop detection in AIS data, featuring the recently added trajectory styling using interpolated lines:

• sur GIScussions: Geomob London – a Cracking Night of Maps

  Publié: 26 January 2024, 3:38pm CET

  

  I must have said this before but I will say it again, if you live anywhere near to London and you are into geotech, maps or location influenced applications then you should give Geomob a try. I’d offer you a money back guarantee but as it’s free that isn’t necesary but more on that later.

  On Wednesday night (24th Jan 2024) we had nearly a hundred people attending what truly was a cracking event, the room was full (almost overfull), the speakers were eclectic, wide ranging and brilliant, the conversation was sparkling and mappy and it was a treat to be able to stand outside the pub drinking in January.

  For a run down on the 5 speakers and their talks have a look at the @Geomob thread on mastodon

  The talks covered a new javascript library, a Welsh language version of OSM, crowd sourcing neighbourhood boundaries in New Zealand, mapping bus routes and stops in India and the audience favourite (and mine) A Map Inside. This was a perfect selection of talks, technical, quirky, passionate and absorbing. As always, the best is saved for the end when we go to the nearby pub and chat, make new friends and discover new opportunities.

  There is something very special about Geomob and that is perhaps evidenced by its expansion from its origins in London to regular events in Barcelona, Berlin, Finland, Lisbon, Munich and Tel Aviv. Geomob would not be possible without the energy and commitment of Ed Freyfogle whose company OpenCage is the principal sponsor of the events (and the podcast) and the generous sponsors – OpenCage, Mappery, Esri UK, Ed Parsons, Geolytix and SplashMaps.

  But here is the rub, the numbers are increasing (which is good) and beer prices are also increasing (which is not so good) so the cost of running the events is increasing faster than sponsorship. We need more sponsors or larger sponsorship to keep Geomob growing and spreading geo-goodness to a wider audience, can you help us? It could be an individual or a company sponsoring events in a city or worldwide or it could be that you would like to sponsor a podcast episode and get a mention of your organisation as a sponsor in our podcast (great if you are hiring or launching a new service). Ed and I have some ideas for novel approaches to sponsorship and would be happy to discuss them with you, just message me through the contact form.

  Geomob always needs speakers at the events and on the podcast so if you fancy presenting or being interviewed get in touch with us.

• sur Developers invited to the February 2024 OGC API – Coverages Virtual Code Sprint

  Publié: 25 January 2024, 3:00pm CET par Simon Chester

  The Open Geospatial Consortium (OGC) invites developers to the 2024 OGC API – Coverages Virtual Code Sprint, to be held February 13-15, 2024. Registration is free and open to the public.

  The Sprint will focus on refining the OGC API – Coverages – Part 1: Core candidate Standard. OGC API – Coverages enables clients to efficiently retrieve a subset of spatiotemporal data for a given time, area, and resolution of interest through a simple Web API. 

  Typically, this data is returned in a gridded format such as netCDF, GeoTIFF, CoverageJSON, or CIS JSON, although this also extends to other coverage data types, such as point clouds in e.g. LAS/LASZip format, or tiled coverage data. The candidate Standard also supports the listing and retrieving of data and metadata for individual scenes making up a coverage.

  Example types of coverages, sometimes called GeoDataCubes, include weather and climate datasets, Earth Observation time series, static environmental data such as digital elevation models, land cover classification, and point clouds obtained from LiDAR capture or photogrammetry. Furthermore, in recent OGC activities, the development of a proposed GeoDataCube API Standard has leveraged OGC API – Coverages as a Core foundation for data access. 

  An OGC Sprint is a collaborative and inclusive event driven by innovative and rapid programming with minimal process and organization constraints to support the development of candidate standards and applications that implement those standards.

  During the virtual code sprint, there will be an opportunity for joint discussion with all participants on the goals and objectives of the event, as well as the final briefing of findings and opinions of the participants. However, the majority of the time will be spent in collaboration between participants in active coding. 

  To learn more about how the family of OGC API Standards work together to provide modular “building blocks for location” that address both simple and the most complex use-cases, visit ogcapi.org. For more technical information about OGC Standards, including how to get started, links to each Standards’ GitHub page, official Standards documents, compliance, and more, visit developer.ogc.org

  The Sprint will take place on GoToMeeting and Discord platforms from 8:00am to 6:30pm (US Eastern) each day from February 13-15, 2024. 

  For more information on the Sprint, including objectives, agenda, and registration, visit the February 2024 OGC API ? Coverages Virtual Code Sprint wiki page on GitHub. Information on other OGC Sprints or events for developers can be found on the OGC Developer Events wiki on GitHub.

• sur Stefano Costa: I libri che ho letto nel 2023

  Publié: 20 January 2024, 12:46pm CET

  Fine anno, tempo di elenchi (bilanci, no). Nel 2023 ho letto pochino.

  David Graeber, Debito

  Questo è il libro che mi ha impegnato per più tempo. È un saggio, ed era da tempo che non leggevo un saggio, non sono più abituato allo stile e all’impegno richiesto. È un testo rivoluzionario a livello sociologico e psicologico (smonta il senso di colpa!) ancora più che a livello economico. Ha uno stile abbastanza scorrevole (per me) ma comunque è denso di nozioni, confronti tra fatti e conseguenze scagliate come frecce ad ogni pagina. Non conoscevo David Graeber prima della pubblicazione postuma del libro L’alba di tutto (The dawn of everything), scritto a quattro mani con l’archeologo David Wengrow. Ho pensato che non ci fosse nessuna fretta e fosse invece un bene partire da qui per conoscere il lavoro di Graeber, e sono contento di averlo fatto.

  Enzo Barnabà, Morte agli Italiani!

  Il massacro di Aigues-Mortes, che il 17 agosto 1893 costò la vita a nove operai italiani linciati da una folla inferocita, rappresenta un episodio capitale nella storia dei rapporti tra l’Italia e la Francia.

  Questo libro di Enzo Barnabà è breve, preciso e senza orpelli.

  Racconta la tragedia del massacro di Aigues-Mortes, le premesse che lo hanno reso possibile, le conseguenze che ebbe in Italia capaci di sconvolgere gli assetti politici sia del governo sia delle giovani formazioni socialiste.

  Lucia Tozzi, Dopo il turismo

  Questo libro è stato scritto di getto nei mesi del lockdown. Trafigge come una spada convinzioni e luoghi comuni, in modo anche un po’ crudele. Il turismo è insostenibile. Distrugge le comunità delle persone, i luoghi abitati da queste comunità.
  
  Sono passati appena 3 anni e sembra la cronaca della rivoluzione mancata di un altro pianeta. Abbiamo già dimenticato tutto quello che è accaduto e quello che avrebbe potuto accadere.
  
  Il libro può essere “acquistato” gratuitamente in formato ePub dal sito dell’editore nottetempo.

  Luca Mercalli, Salire in montagna

  La cosa che mi fa incazzare di questo libro è che è scritto da una persona di cui avevo una stima incondizionata, frutto di altre letture (non della trasmissione televisiva). Ma questo libro sembra scritto da Paolo Rumiz. Infatti Mercalli ce l’ha con chi abita in montagna, con chi non ci abita più, con chi non ci abita e non ci ha mai abitato. Lo scopo principale del libro è lamentarsi della burocrazia che gli impedisce di costruire la sua seconda casa, dove può trovare riparo dalle zanzare della sua abitazione indipendente di pianura. Salire in montagna sarebbe un antidoto al riscaldamento globale, dice il sottotitolo, ma se va bene dire una fesseria del genere al bar, trovarlo propagandato da un climatologo fa per l’appunto incazzare. Le montagne tutte e in particolare le Alpi sono uno degli ecosistemi più fragili di fronte al cambiamento climatico, e per fortuna questa semplice nozione fa capolino qua e là tra le pagine del libro. Costruire una casa recuperando un edificio storico invece che buttarlo giù è una bella cosa, molto costosa (ma Mercalli alla fine non ci dice quanto) ma ne vale la pena perché potremmo ripopolare la montagna lavorando al computer, secondo la logica deformata di questo libro. Non ne sopporto l’idea di fondo perché è la propaganda di una idea individualista, come se i venti milioni di abitanti della pianura padana potessero trovare spazio per la loro seconda casa sulle montagne e salvarsi così tutti dal riscaldamento globale (che li lascerà comunque a morire di fame). E nelle prime pagine è riportata virgola per virgola una pseudoetimologia sull’idronimo della Dora presa da Wikipedia, che mi ha reso da subito indisposto. E non c’è nemmeno una carta geografica.

  Assia Djebar, Bianco d’Algeria

  Questo libro è sicuramente quello che ho faticato di più a leggere, nonostante non sia molto lungo. Trasuda nella sua componente principale un dolore immenso, il dolore di un popolo intero. Parla dello sradicamento ineludibile di chi deve usare la lingua degli oppressori per esprimersi, anche quando questa espressione raggiunge livelli altissimi e anche quando gli oppressori francesi si manifestano come la più grande sciagura mai accaduta al popolo algerino. Parla di profondissimi legami con le persone che per la libertà hanno messo tutto il proprio corpo e non solo il proprio intelletto, a costo di perdere la vita.

  Chinelo Okparanta, Sotto gli alberi di udala

  Questo libro inizia con una carta geografica della Nigeria, e questo potrebbe essere sufficiente a metterlo vicino al mio cuore (perché mi piacciono molto le carte geografiche). Ritrovo il Biafra devastato e dilaniato dalla ferocia della guerra civile di Metà di un sole giallo, con un pesantissimo supplizio in più. La protagonista è costretta a vivere con crescente angoscia la propria omosessualità, perché in Nigeria è un peccato mortale che viene punito in modo sommario, anche con linciaggi. Ma nella seconda parte si riaccende la speranza. È la stessa Africa dove oggi vacilla un po’ il colonialismo europeo.

  Beata Umubyeyi Mairesse, I tuoi figli ovunque dispersi

  Anche questo libro è un racconto di sradicamento, che attraversa più generazioni. Tra Ruanda e Francia, tra nonna, madre, figlio, la protagonista trova un senso, anche linguistico, al proprio passato e al proprio futuro, nonostante il trauma del genocidio, della fuga dal genocidio e dello sradicamento che ne deriva. Bellissimo, straziante e lucido.

  Gabriela Wiener, Sanguemisto

  Anche questo libro è un racconto di sradicamento, che attraversa più generazioni (non ho sbagliato a fare copia e incolla). È un libro molto forte che si aggancia quasi chimicamente con letture accademiche che sto facendo in questo periodo, su archeologia e colonialismo (in Italia non esiste il postcolonialismo). Ma è anche un tripudio agrodolce di femminilità.

  Inizio il 2024 leggendo L’incendio di Cecilia Sala e Tutta intera di Espérance Hakuzwimana.

• sur OGC forms new GeoZarr Standards Working Group to establish a Zarr encoding for geospatial data

  Publié: 18 January 2024, 3:00pm CET par Simon Chester

  The Open Geospatial Consortium (OGC) is excited to announce the formation of the OGC GeoZarr Standards Working Group (SWG). The new SWG will develop a Zarr encoding for geospatial gridded data in the form of Zarr conventions.

  Zarr is a cloud-native data format for n-dimensional arrays that enables access to data in compressed chunks of the original array. Zarr facilitates portability and interoperability on both object stores and hard disks. 

  As a generic data format, Zarr has increasingly become popular to use for geospatial purposes. As such, in June 2022, OGC endorsed Zarr V2.0 as an OGC Community Standard. The purpose of the GeoZarr SWG is to have an explicitly geospatial Zarr Standard (GeoZarr) adopted by OGC that establishes flexible and inclusive conventions for the Zarr cloud-native format that meet the diverse requirements of the geospatial domain. These conventions aim to provide a clear and standardized framework for organizing and describing data that ensures unambiguous representation.

  The objectives of GeoZarr conventions include:

  1. Compatibility: Ensuring easy compatibility with popular mapping and data analysis tools such as GDAL, Xarray, ArcGIS, QGIS, and other visualization tools, enabling seamless integration into existing workflows.
  2. Dimensions: Supporting multi-dimensional data, such as hyperspectral and altitude information, to address diverse geospatial data requirements.
  3. Data Discovery: Providing metadata for discovering, accessing, and retrieving the data, including composite products made of multiple data arrays.
  4. Mixing Data: Facilitating the combination of different types of geospatial data, including satellite images, elevation maps, and weather models, to create comprehensive and informative datasets.
  5. Flexibility: Allowing scientists and researchers to work with diverse data types and projections in their preferred software and programming languages, promoting flexibility and adaptability in geospatial data processing and analysis.

  In addition to the encoding of geospatial data and metadata, the GeoZarr Standard will provide a multi-dimensional alternative to the two-dimensional Cloud-Optimized GeoTiff format (COG – adopted by OGC in May 2023), which has lately gained popularity due to its serverless capabilities. These capabilities will allow for inherent support of traditionally server-based functions, such as visualization (similar to OGC API – Maps), data subset access (analogous to OGC API – Coverages), and symbology (equivalent to OGC API – Styles). These aspects are planned to be incorporated as optional profiles (e.g. conformance classes).

  OGC Members interested in staying up to date on the progress of this standard, or contributing to its development, are encouraged to join the GeoZarr Standards Working Group via the OGC Portal. Non-OGC members who would like to know more about participating in this SWG are encouraged to contact the OGC Standards Program.

• sur Insights from Innovation Days 2023

  Publié: 17 January 2024, 11:44am CET par Simon Chester

  At the end of another year of prototyping software, experimenting with data access, and debating how to overcome geospatial technology’s many challenges, teams from OGC member organizations gathered in Washington DC to share 2023’s work and help OGC decide what challenges we should address in 2024.

  Representatives of government agencies and industry – from FEMA and Natural Resources Canada, to Intact, Canada’s largest insurer – highlighted their successes, current needs, and aspirations. Through panel discussions, demos, and conversations over coffee, teams from startups, like FloodMapp and Navteca, to established industry players, like Bentley Systems and GDIT, shared what they could do to meet today’s needs and shape the tools and systems we’ll be using next. 

  Here are three key takeaways learned from listening in:

  • While looking at maps is the obvious way to interact with spatial data, advances in Artificial Intelligence (AI) mean that a conversation with a map may become normal. Though what this change implies is less clear. 
  • Sensors, surveys, and citizens continue to produce data at scale. Different approaches – from indexing and cataloging to tagging and the semantic web – help us navigate this endless sea of data, yet too often unable to find the right data when we need it.
  • If we were to add another ‘A’ to the FAIR Principles, it might stand for ‘Actionable.’ Even when you can find the data you need, access it, and combine it with other data, robust methods for transforming all that data into actionable intelligence remain limited. The push for organizations to report on how their data supports their decisions may, in 2024, drive collaboration on Standards for describing chains of modeling, inference, and reasoning.

  Moderator Eldrich L. Frazier (FGDC and panelists Ryan Ahola (NRCan), Matt Webster (Barbaricum) Tom Landry (Intact Financial Corporation) and Jim Antonisse (WiSC) discuss the transformative power of Geospatial Artificial Intelligence (GeoAI). AI is changing how we interact with maps and spatial data

  Following the late 2022 public launch of ChatGPT, “AI” became mainstream in 2023 – and its applications in geospatial broadened. This was clear at Innovation Days 2023. 

  In the early 2020s, excitement around AI in the geospatial tech community centered around automating the laborious process of identifying the important objects in satellite images and pulling out key data points from large datasets. This transformed the work of many geospatial analysts and developers, as noted by AI Panel chair Rich Frazier (USGS), but had limited impact on how most people interact with maps and spatial data. The panel’s conversation on AI centered on the potential consequences of our newfound ability to speak to an AI tool and ask it to create a map or run a spatial analysis.

  Many of us are already doing this in specific contexts, such as asking your phone for driving directions, but advanced spatial analysis still requires mice and menus. This is why Natural Language Processing (NLP) felt like such a breakthrough in 2023. First, it has the potential to bypass specialized software and technical language and almost remove the barrier to entry for harnessing geospatial data. It’s therefore no surprise that NLP featured in several presentations, including those by Navteca co-founder Shayna Solis and Voyager Search’s founder Brian Goldin. Additionally, it might let developers and analysts operate more efficiently and create better products. As highlighted by Matt Webster of Barbaricum, who paraphrased economist Richard Baldwin from his presentation at the May 2023 World Economic Forum’s Growth Summit, “AI won’t take your job, but someone using AI will.” The specialist using NLP AI technology has another tool to deploy and they’re likely to use it to their advantage.

  Shayna Solis, CEO & Co-founder of Navteca demonstrated using Conversational AI to interact with geospatial data for disaster response.

  The takeaway is that the current stage of AI not only democratizes access to geospatial information but also enhances user experience and engagement – if we can learn to ask the right questions with the right words. This is the sticky part of the problem. If geospatial really is in everything, there’s a diverse set of questions (aka prompt engineering) for us to teach the NLP AIs to understand. The organizations who gathered at Innovation Days 2023 might start building lots of one-task NLP tools, proliferating the “driving directions” application, or aim for more general ways of describing our mapmaking aims when we speak with an AI tool. Either way, this area looks set for a busy 2024. 

  Finding the right data when we need it is still too hard

  “When it comes to asset-scale climate resilience planning, most people don’t want data, they want data-based answers to key questions. Our challenge is helping them extract actionable intelligence from our data in the form of plain-language answers to their questions.”

  David Herring, Communication, Education and Engagement Division Chief – NOAA Climate Program Office.

  A common refrain at Innovation Days 2023 was the ongoing difficulty surfacing the ‘right data’ when it’s needed. Scott Kaplan (USGS, Civil Air Patrol) spoke about the critical need for the ‘right data’ to support crews fighting wildfires. Kasie Richards (American Red Cross) called out the need for the ‘right data’ for planning for future patterns of extreme weather events that will look different from the past. Tom Landry (Intact) pointed to the need to enable public-private partnerships that could make the ‘right data’ held by private entities discoverable and usable for applications that benefit the public.

  Catalogs, indexes, semantic knowledge organization systems, and machine-readable metadata systems have proliferated as organizations attempt to keep pace with the growth in data, but the conversations among panelists suggest that these approaches haven’t solved the problem – and it’s worsening as more data is generated.

  Alan Lediner (NYC GISMO) characterized the inability to ask for and find what we need in all this data as a “communication problem.” This framing links what we’re stuck on (finding the right data) to where we’re moving toward (using natural language prompts) but requires (again) that we figure out how to describe what we mean when we say ‘the right data.’

  Discussions about how to find the right data were threaded throughout the panels at Innovation Days 2023, highlighted by Alan Leidner speaking about data for emergency response.

  There’s another factor that makes addressing the findability problem particularly urgent for 2024: spiraling costs due to duplication. People often make local copies of data they think they’ll need so that they can later access it quickly and reprocess it on their own infrastructure. Dave Borges (CEOS, NASA) pointed to the unintended consequences of this widespread practice: spiraling financial (and environmental) costs, and, perversely, greater difficulty finding the ‘right’ version of a dataset, as multiple organizations make their own versions of datasets cloud-accessible. It’s hard to see us breaking this habit without creating confidence that other organization’s datasets will be findable (and generally FAIR) when they’re needed. Designs that account for people’s behavior and attitudes toward their data sources may push forward Findability as the organizations gathered at Innovation Days 2023 build the next cloud-native geospatial systems.

  Data is actionable when it is accountable

  Responding to emergencies, preparing for future extreme events, and redesigning infrastructures for resilience in a changing climate are all high-stakes uses of geospatial data and technologies that impact lives and communities. Craig Fugate (FEMA), in his keynote at Innovation Days 2023, emphasized these impacts. 

  Craig Fugate, Former Administrator, Federal Emergency Management Agency (FEMA), during his keynote address.

  Craig encouraged us to think differently about our challenges, suggesting specific changes like taking a “maximum of maximums approach” when formulating an emergency response plan that can quickly scale up the response as an emergency is unfolding. Equally important, in his judgment, were proposed changes to longer term planning and response, such as explicitly considering equity and equality when planning how to deploy resources to prevent disasters or rebuild after they occur. This push for innovation, many years in the making and challenging in its own right, is facing new complications as it intersects with a growing drive for accountability. 

  Accountability, and the ability to demonstrate that decisions were backed by sound data and reasoning, is emerging as an essential part of decision-making processes – particularly for government and public sector organizations. It’s also supporting new, effective practices because it can allow people and organizations to confidently back the changes made. Synthesizing comments from Shanna McClain (NASA), Norman Speicher (DHS), and Ryan Ahola (NRCan), this in practice means the geospatial community needs to develop methods and systems that allow audits of the complex chains of data, models, tools, and people that inform decisions.

  Building these methods and systems will require organizations to grapple with how we express uncertainty, which is only compounded by the growing use of AI tools. One example of how this challenge may play out came from the AI Panel’s discussion on visually representing results in ways that won’t impart false confidence. Juliette Murphy’s (FloodMapp) presentation provided another, highlighting the challenges of getting people to think in terms of probabilities when buying a home in a flood-prone area. Looking to 2024, expect to see considerations of uncertainty and accountability continue to intersect as new geospatial approaches to climate & disaster resilience are developed.

  Juliette Murphy (FloodMapp) discusses the challenges of conveying uncertainty, probability and risk. What comes next?

  The tendency for geospatial organizations to operate as “Silos of Excellence” was a common theme brought up by several speakers at Innovation Days 2023. The collaborative, consensus-driven approach that underpins all activities at OGC is a proven method for overcoming this challenge. Progress in 2024 will require more collaboration across the community, including between those who use geospatial tools and those affected by the decisions they’re informing. Indeed, how we interact with location data, how we find the geospatial information we need, and how we make data-driven decisions accountable are all issues being tackled by our community through OGC COSI Initiatives, Working Groups, and events. A few to look out for in 2024:

  • The OGC Artificial Intelligence in Geoinformatics Domain Working Group (GeoAI DWG) is exploring the implications of natural language processing (NLP) integration with GIS. This public group is broadly focused on fostering collaboration among diverse stakeholders to address gaps and impacts of AI on OGC standards, and is launching a monthly speaker series in early 2024.
  • SpatioTemporal Asset Catalog (STAC) is a proposed OGC Community Standard that conforms to OGC APIs and provides an interoperable metadata framework that simplifies the process of finding and using geospatial assets from different providers.  In 2024, multiple OGC Code Sprints will continue to give our community a platform to collaborate on emerging OGC and Community Standards and implementations.
  • Trust is an essential component of producing actionable geospatial intelligence. As the push continues towards interoperable tool chains for modeling, inference, and reasoning, Standards such as OGC Training Data Markup Language for Artificial Intelligence (TrainingDML-AI) can improve trustworthiness by formalizing how modeling training data is prepared, including data provenance and quality. The Training Data Markup Language for AI Standards Working Group will continue this important work in 2024.
  • The Climate and Disaster Resilience Pilot will kick off in Spring 2024, continuing to prototype new Standards-based tools, models, and methods for critical applications – from building warning systems that support natural disaster response to integrating Climate models into emergency management planning. There’s still time to apply to participate and receive funding to address these critical challenges.

  By necessity, this blog is only able to cover a small snapshot of the many discussions, insights, and conversations resulting from OGC Innovation Days 2023. A big thank you goes out to all the presenters, panelists, attendees, and other OGC community members that helped make it such a success.

  We look forward to seeing many of our community members at the 128th OGC Member Meeting in Delft, Netherlands, March 25-29, and later at OGC Innovation Days 2024.

• sur Announcing the 2024 Joint OGC ASF OSGeo Code Sprint

  Publié: 12 January 2024, 3:00pm CET par Simon Chester

  The Open Geospatial Consortium (OGC), Apache Software Foundation (ASF), and Open Source Geospatial Foundation (OSGeo) are pleased to announce the date of the 4th annual Joint OGC ASF OSGeo Code Sprint as February 26-28, 2024.

  As a hybrid event, the face-to-face component will be held in Casa Cordovil-Universidade de Évora (Évora, Portugal), while the virtual component will be held via the OGC Events Discord server. Registration for the code sprint is free and open to the general public here.

  The code sprint will be hosted by Universidade de Évora, NaturalGIS and Geobeyond. Catering will be sponsored by NaturalGIS, Geobeyond and the European Union-funded GEOE3 project. Further sponsorship opportunities remain available: see below for more information.

  The code sprint will engage with multiple ASF and OSGeo projects, supported by OGC Standards – including OGC API Standards, the building blocks for location on the web. All OGC, Apache, and OSGeo projects, working groups, and members, as well as the wider public, are encouraged to participate. In addition to developers, technical writers are also encouraged to participate to help the various projects and working groups with their documentation.

  A code sprint is a collaborative and inclusive event driven by innovative and rapid programming with minimal process and organization constraints to support the development of new applications and candidate Standards.

  The goal of the 2024 Joint OGC ASF OSGeo Code Sprint is to advance support of open geospatial Standards within the developer community, while also advancing the Standards themselves. The code sprint will provide software developers a period of three days in which to focus on projects that implement open geospatial Standards.

  There will be an opportunity for joint discussion with other participants, as well as daily briefings from each project and working group. However, the majority of the time will be spent in collaboration between participants in active coding and related activities such as testing, reporting issues, and working on documentation. 

  The sprint will also provide a mentor stream that’s aimed at developers who are not yet familiar with the software projects and Standards. Through tutorials and 1:1 mentoring, the mentor stream aims to support developers in taking the first steps in their journey toward mastery of open geospatial Standards and projects.

  For more information on the code sprint, including registration, the projects and Standards involved, and FAQ, visit the 2024 Joint OGC-ASF-OSGeo Code Sprint website. Registration for in-person participation closes at 9:00am WET on the 19th of February, 2024. Registration for remote participation will remain open throughout the code sprint.

  To set the context of the code sprint, and to help participants prepare, there will be a one-hour pre-event webinar on Discord at 14:00 WET/UTC/GMT, on February 20.

  The agenda and other logistical information about the code sprint can be found on the 2024 Joint OGC – OSGeo – ASF Code Sprint GitHub Wiki. Information on other OGC Sprints or events for developers can be found on the OGC Developer Events wiki on GitHub.

  Publié: 1 January 2024, 12:00am CET

  I've registered for the Never Summer 100K (my 3rd) at the end of July, the Black Squirrel Trail Half-Marathon (my 4th) in early September, and the Bear 100 Mile at the end of September (my 2nd try). All are events that I've run before, but never as a set. I ran Never Summer and Black Squirrel together in 2021. I did the shorter 60K version of Never Summer last year along with the Bear.

  I intend to do Never Summer as part of my build up for the Bear 100. I'll give it a good go, but stay composed, and be mindful that it will be just the first week of my peak training block. I registered for Black Squirrel because I've missed running it, could be really fit that week, and some faster running might be a fun break from the long slogs of late summer.

  Finishing the Bear 100 is my number one goal. I'd like to finish and do well at Never Summer and Black Squirrel, too, but am ready to sacrifice these goals if I must.

  Along the way to finishing the Bear I'm going to try to add 250 miles at 220 feet per mile to last year's numbers, so 1850 miles running and 275,000 feet of climbing. This is feasible if things go well. I ran 2000 miles in 2021.

  I aim to lose at least 15 pounds in the next 9 months so I don't have to drag them for 30 hours through the mountains of Utah and Idaho. I'll have to omit junk food and DIPAs to do it. In their place, I can work on training my stomach to handle Spring Energy gels.

  My last goal is to increase the flexibility and durability of my ankles so that I have a better chance of weathering the trails of the Bear in 2024. I'm planning to get some physical therapy help on this early this next spring.

  Good luck in reaching your own goals for next year, whether they are on or off trail!

  Publié: 31 December 2023, 2:34am CET

  2023 was a pretty good running year. I was both ambitious and conservative, overcame some adversity and learned a lot. The numbers for 2023:

  • 363 hours

  • 1610 miles

  • 220,128 feet D+

  • 3 ultra finishes

  • 1 DNF

  Coming off a down year, I signed up for my first 100 mile run, and tried to do it on fairly minimal training relative to the big miles I ran in 2021. I got my third Quad Rock 50 mile finish in May, did the Kettle Moraine 60K fun run in June, and the Never Summer 60K in July.

  I had to manage and run through an episode of intense back pain in July, but recovered in time for the Bear 100 in September. At that race I was on track to finish in less than 36 hours, but wrecked my left ankle and dropped out at 61 miles. I'm going to try it again.

  I ran fewer miles than in 2019-2021 years, but did a lot of climbing (including a new weekly total high), and started 4 ultra-marathons. That's a new high for me.

  In 2024, I'll be trying a different mix of events. And I'll be back here at Kelly Lake.

  Publié: 30 December 2023, 1:38pm CET

  I'm glad to announce the update of Remotior Sensus to version 0.3.The main new feature is a new module for displaying an interface similar to the Semi-Automatic Classification Plugin (which is based on Remotior Sensus) in Jupyter notebooks.Jupyter notebooks are interactive documents that can be edited in a web browser, which allow for coding in Python and interact with widgets.
  The Jupyter interface is still in development and only a few tools are available. For the moment, the available tools are:

  • search and download of remote sensing images;
  • creation and management of Band Sets;
  • the dock for creating a training input and saving ROIs created interactively through polygons or region growing;
  • the import of vectors in training input;
  • the plot of spectral signatures;
  • the classification of the Band Sets;
  • a file browser for selecting files or directories.

  For example the following command displays the interface for downloading products.

  import remotior_sensus
  rs = remotior_sensus.Session(n_processes=2, available_ram=1000)
  rs.jupyter().download_interface()

  
  
  
  Of course this is a proof of concept, considering that this interface doesn't have all the functions of the Semi-Automatic Classification Plugin, and there are a few differences in the look and feel because of the characteristics of Jupyter notebooks.A tutorial describing this new feature will be released soon.
  For any comment or question, join the Facebook group or GitHub discussions about the Semi-Automatic Classification Plugin.

  Publié: 29 December 2023, 4:58pm CET

  Dear all, it has been a while, but some stuff has been going on in the SMASH community. And we now have a new release. So let's have a look at what is new.

  
  

  We farewell the play store

  It is a while we have additional work to do and are loosing usability in SMASH due to the restrictions imposed by the google store. The most impacting has sure been the fact to not be able to access the phone memory freely. And asking google permission to do so didn't work out, since it seems that only file browsers applications and antivirus need to access the memory freely.

  With the help of the F-Droid community (special thanks to IzzySoft, Linsu and Licaon-kter) we have been able to make our second appearance on the f-Droid store. And that is now enough to completely migrate there. So we made a last release of SMASH for the store today, but it will be the last one. Please from now on come and get SMASH from the F-Droid store, where the real open source apps live.

  Flutter map
  

  We finally made an upgrade of flutter_map, the map widget library used. This took so long, because the architecture of the library had changed and took some rework inside SMASH.
  

  And now on to the new features:
  

  Geometries inside forms

  One nice addition that we have to thank Luca Delucchi and the Digiagriapp for is the possibility to insert inside of complex notes.
  

   

  URL based forms combos

  It is now possible to insert in forms URLs to substitute long item lists in comboboxes (dropdown lists). This allows forms to be smaller in case of large amounts of items and also to be more dynamic.
  

  Gejson layer support

  Geojson is now one of the supported formats in read and write mode (together with geopackage and postgis). It can be used in combination with sld styling as for the other vector formats.

  More efficient toolbar
  

  The toolbar has been redone with more usability in mind.

  Editing is done on a sidebar now:

  and in the settings it is possible to remove unused buttons:

  leads to:

   

   Other tiny things that might be worth telling
  

  • now the default behavior of tile maps is to zoom beyond the max zoom level by scaling (no more white emptiness)
  • the current log panel has now 3 sizes for better overlay on map
  • the info tool is now a box selection tool and as such way more usable
  • online sources have been reworked to have the possibility to add and remove from the default. Also the default maps have been reviewed to ensure they are working
  • feature info now also presents the length and area of the geometry as derived value
  • we did many many bugfixes

  One last thing to add. SMASH 1.8 already presents the possibility to import layers from the new GSS server. This is still in testing mode and ongoing work with the Region Piemonte and not yet disseminated as such. Just to give an idea, it will be possible to generate database tables on the server based on form definitions and download the tables as layers from the GSS and sync them two-ways. Also it will allow for point, line and polygon geometries. All in all it will be an alternative way to take notes, still using the form system and having a way to synchronize data to teh central server instance. But well, this will probably be the next story to tell, once testing is done.

  Enjoy!!

  Para despedirnos por este año elegimos comentar otro proyecto que bien podía haber integrado la lista de finalistas, y que por el altísimo nivel alcanzado, tal vez injustamente, ha quedado fuera del podio:

  Título: 10 años del Geoparque Mundial UNESCO Grutas del Palacio
  Institución: Liceo Departamental N° 1
  Localidad: Trinidad
  Docente de referencia: Gerardo Moraes
  Tutora: Nadia Chaer

  Queremos resaltar especialmente este proyecto por varias razones:

  • porque realizaron una publicación como parte del proyecto, en la que utilizaron los mapas creados con gvSIG Batoví
  • porque los estudiantes extendieron lo que habían aprendido a otros estudiantes, en este caso de Educación Primaria, a través de la realización de varios talleres en la escuela N°31 de Trinidad, departamento de Flores (Uruguay); pueden ver un video aquí
  • y porque presentaron su proyecto de una forma muy interesante, amena e interactiva

  Este proyecto, realizado por estudiantes de 5° Humanístico (16 y 17 años), ha destacado también por la gran cantidad y calidad de trabajo producido: hasta elaboraron los diplomas a entregar a los participantes de los talleres escolares antes mencionados.

  Nuestras felicitaciones a todo el equipo por el estupendo proyecto que han desarrollado (¡en sólo 3 meses!). Y nuestras felicitaciones también a todos los demás equipos porque, como dijimos anteriormente, en esta iniciativa no hay perdedores, sólo ganadores.

• sur QGIS España: Participación en la GeoCamp 2023

  Publié: 27 December 2023, 3:00pm CET

  GeoCamp ES

  GeoCamp es un congreso nacional sin ánimo de lucro, que nació en 2013 y que organiza anualmente el colectivo internacional de Geoinquietos. Esta Comunidad está formada por grupos informales que se reúnen para hablar y aprender sobre cualquier tema relacionado con las ciencias de la tierra y que siente una especial afinidad por los servicios de geodatos abiertos, proyectos comunitarios, software libre y aplicaciones SIG (Sistemas de Información Geográfica), especialmente los desarrollados en torno a la comunidad OSGeo (Open Source Geospatial).

  Este año Geocamp ha celebrado su 10ª Edición en septiembre en la isla de la Illa de San Simón en la ría de Vigo (Galicia - España) y ha tenido un formato Open Space, donde todos los participantes tienen un papel activo en la realización del evento para aumentar la interacción entre los asistentes para poder, con agilidad e improvisación, satisfacer espontáneamente las inquietudes de los participantes.

  Empezó el evento con un maravilloso día soleado y con la isla de San Simón recibiendo a los más de 40 participantes que llegamos en barco desde el puerto de Vigo atravesando la ría, en un viaje muy interesante, amenizado con la información histórica y cultura local de mano de los tripulantes. La pequeña isla con sus históricos edificios donde se podían configurar varios espacios, permitió la realización de numerosas actividades y reuniones, tanto dentro como en el exterior.

  A lo largo de la jornada se pudieron realizar seis espacios abiertos donde se habló y debatió sobre los temas que se eligieron por la propia iniciativa, interés y propuestas de los asistentes, y que fueron votados y aceptados por todos y cuyos puntos a destacar se pueden consultar aquí, documento resumen elaborado de forma conjunta por los participantes: OSM, Las Calles de las Mujeres, Geoportales participativos, JS y Web GL, Inteligencia Artificial y mapas, Teledetección, estado de las Comunidades, Estándares OGC y Blockchain.

  La charla plenaria que ofreció Carmen Torrecillas de la organización Civio nos mostró cómo hacer mapas y visualizaciones increíbles, gracias al gran trabajo que hacen por la transparencia y la vigilancia de los poderes públicos.

  Por supuesto, además, se comentaron todo tipo de inquietudes, experiencias, proyectos y objetivos (cómo la forma de manipular un pixel en la GPU, monitoreo de cetáceos, cooperativas, Joomla, montañismo, conjuros, etc.) a lo largo de todos los momentos en los que se pudo charlar mientras se disfrutaba de los ricos manjares gallegos, con los que se amenizaron los desayunos, comida y cena en un ambiente amable y creativo. Incluso pudimos disfrutar de fantásticas experiencias de la mano de nuestros organizadores fuera de programa como un concierto de rock ( @fpsampayo) o una queimada ( @michogar) cómo no podía ser de otra manera en esta maravillosa ciudad gallega.

  La organización local reservó una cena para aquellos que querían seguir compartiendo charlas y espacio. Aunque no es algo estrictamente necesario en un evento participativo como este, siempre ayuda a crear contactos y sinergias. De hecho, muchos de los asistentes, sobre todo si han tenido que venir de otras partes de la península y tienen que hacer noche en la ciudad, lo agradecieron y acudieron para cerrar de una manera festiva el encuentro.

  Como conclusiones, señalar que el formato de Open Space funcionó muy bien, contando con un amplio espacio disponible lo que facilitó la organización e incluso la gente se podría haber repartido en más grupos si hubiera sido necesario. De hecho, con grupos algo más reducidos se puede trabajar mejor la participación, aunque fue en éxito con grupos de unas 20 personas. Fue de agradecer haber previsto, mediante un formulario que se hizo llegar a los asistentes, una serie previa de temas a tratar agilizando la organización de los grupos. Realmente es un formato único para crear comunidad, aprender cosas nuevas y llevarse a casa un buen número de conocimientos e ideas. Muy gratificante haber podido conocer gente que no sabía lo que era este tipo de evento y que se encuentran con una experiencia realmente satisfactoria, donde se han podido compartir conocimientos en un ambiente participativo y distendido, que ayuda realmente a contactar a personas que ya tienen experiencia con otras que pueden estar empezando.

  Habrá que esperar al año que viene para volver a disfrutar de nuevo de un encuentro tan especial como este.

  Dear QGIS Community,

  We recently held our 2023 QGIS Annual General Meeting. The minutes of this meeting are available for all to view.

  This year, we did not have PSC elections. Anita Graser will continue as Vice-Chair, I will continue to serve on the PSC as chair, and our longstanding treasurer, Andreas Neumann, will complete the board. Furthermore, Jürgen Fischer, Alessandro Pasotti, and Régis Haubourg will continue on the PSC. Last but certainly not least, the PSC is completed by our project founder, Gary Sherman, and long-term PSC member Tim Sutton, who serve on the PSC as honorary PSC members. They both set the standard for our excellent project culture, and it is great to have his continued presence.

  QGIS has been growing from strength to strength, backed by a fantastic community of kind and collaborative users, developers, contributors and funders. This year, we reached another important milestone for the project’s sustainability by welcoming our first flagship sustaining member – Felt. I look forward to seeing how it continues to grow and flourish.

  Rock on QGIS!

  Cheers

  El proyecto fue elaborado por estudiantes del Liceo Nº2 Dr. Antonio M. Grompone de la ciudad de Salto, siendo su docente de referencia la profesora María Patricia Leal, y su tutor Carlos Lara de la Facultad de Ciencias de la Universidad Católica de la Santísima Concepción (Chile). El tema del proyecto fue realizar un estudio descriptivo sobre las condiciones ambientales que favorecen la proliferación del vector Ludzomia Longipalpis, para promover acciones de salud tales como la promoción y prevención de la Leishmaniasis Visceral, que impacten positivamente a nivel comunitario.

  Y debemos decir que los estudiantes integrantes del equipo (de 14 y 15 años de edad) hicieron algo que parecía difícil de conseguir: mejorar lo hecho el año anterior. Se trata de un gran trabajo que destaca tanto por la cantidad como por la calidad del material producido, que trascendió ampliamente los objetivos del concurso (por ejemplo, en la invención de un repelente natural contra el flebótomo (vector de trasmisión de la leishmaniasis) y de una trampa de luz para su captura)

• sur Paul Ramsey: Data Science is Getting Ducky

  Publié: 19 December 2023, 5:00pm CET

  For a long time, a big constituency of users of PostGIS has been people with large data analytics problems that crush their desktop GIS systems. Or people who similarly find that their geospatial problems are too large to run in R. Or Python.

  These are data scientists or adjacent people. And when they ran into those problems, the first course of action would be to move the data and parts of the workload to a “real database server”.

  This all made sense to me.

  But recently, something transformative happened – Crunchy Data upgraded my work laptop to a MacBook Pro.

  

  Suddenly a GEOS compile that previously took 20 minutes, took 45 seconds.

  I now have processing power on my local laptop that previously was only available on a server. The MacBook Pro may be a leading indicator of this amount of power, but the trend is clear.

  What does that mean for default architectures and tooling?

  Well, for data science, it means that a program like DuckDB goes from being a bit of a curiosity, to being the default tool for handling large data processing workloads.

  What is DuckDB? According to the web site, it is “an in-process SQL OLAP database management system”. That doesn’t sound like a revolution in data science (it sounds really confusing).

  But consider what DuckDB rolls together:

  • A column-oriented processing engine that makes the most efficient possible use of the processors in modern computers. Parallelism to ensure all CPUs are made use of, and low-level optimizations to ensure each tick of those processors pushes as much data through the pipe as possible.
  • Wide ranging support for different data formats, so that integration can take place on-the-fly without requiring translation or sometimes even data download steps.

  Having those things together makes it a data science power tool, and removes a lot of the prior incentive that data scientists had to move their data into “real” databases.

  

  When they run into the limits of in-memory analysis in R or Python, they will instead serialize their data to local disk and use DuckDB to slam through the joins and filters that were blowing out their RAM before.

  They will also take advantage of DuckDB’s ability to stream remote data from data lake object stores.

  What, stream multi-gigabyte JSON files? Well, yes that’s possible, but it’s not where the action is.

  The CPU is not the only laptop component that has been getting ridiculously powerful over the past few years. The network pipe that connects that laptop to the internet has also been getting both wider and lower latency with every passing year.

  As the propect of streaming data for analysis has come into view, the formats for remote data have also evolved. Instead of JSON, which is relatively fluffy, and hard to efficiently filter, the Parquet format is becoming a new standard for data lakes.

  

  Parquet is a binary format, that organizes the data into blocks for efficient subsetting and processing. A DuckDB query to a properly organized Parquet time series file might easily pull only records for 2 of 20 columns, and 1 day of 365, reducing a multi-gigabyte download to a handful of megabytes.

  The huge rise in available local computation, and network connectivity is going to spawn some new standard architectures.

  Imagine a “two tier” architecture where tier one is an HTTP object store and tier two is a Javascript single page app? The COG Explorer has already been around for a few years, and it’s just such a two tier application.

  (For fun, recognize that an architecture where the data are stored in an access-optimized format, and access is via primitive file-system requests, while all the smarts are in the client-side visualization software is… the old workstation GIS model. Everything old is new again.)

  The technology is fresh, but the trendline is pretty clear. See Kyle Barrron’s talk about GeoParquet and DeckGL for a taste of where we are going.

  

  Meanwhile, I expect that a lot of the growth in PostGIS / PostgreSQL we have seen in the data science field will level out for a while, as the convenience of DuckDB takes over a lot of workloads.

  The limitations of Parquet (efficient remote access limited to a handful of filter variables being the primary one, as will cojoint spatial/non-spatial filter and joins) will still leave use cases that require a “real” database, but a lot of people who used to reach for PostGIS will be reaching for Duck, and that is going to change a lot of architectures, some for the better, and some for the worse.

• sur Jackie Ng: Minor change of plans

  Publié: 18 December 2023, 12:14pm CET

  There will be a slight change of plans in the MapGuide Open Source 4.0 release timeline.

  Namely, the next release will not be the Release Candidate, but rather a 2nd beta release.

  The main driver behind this decision is because of my intention to remove the recently introduced support for Mapbox Vector Tiles. While I initially had high hopes with this implementation, additional testing with data outside of the example Sheboygan dataset has revealed rendering issues I do not have the capability to address. Rather than ship a half-baked implementation that may never bake fully, I'd rather bow out while we still can, remove this immature implementation, and leave MVT tile generation to dedicated external tools.

  A 2nd beta release will also mean that the other changes I want to get in will also have some time to bake before the Release Candidate stage.

  I am hoping the 2nd beta release will be out late January in the new year.

  Publié: 15 December 2023, 9:59pm CET

  Starting from 3.26, QGIS now supports .vtpk (Vector Tile Package) files out of the box! From the changelog:

  ESRI vector tile packages (VTPK files) can now be opened directly as vector tile layers via drag and drop, including support for style translation.

  This is great news, particularly for users from Austria, since this makes it possible to use the open government basemap.at vector tiles directly, without any fuss:

  1. Download the 2GB offline vector basemap from [https:]]
  

  

  
  2. Add the .vtpk as a layer using the Data Source Manager or via drag-and-drop from the file explorer
  

  

  
  3. All done and ready, including the basemap styling and labeling — which we can customize as well:

  

  Kudos to [https:]] for bringing this new feature to my attention.

• sur 3liz: Sortie extension Lizmap 4.0.0 pour QGIS

  Publié: 15 December 2023, 5:00pm CET

  Nouvelles fonctionnalités sur la validation des projets

  Lors de la publication d'un projet avec le serveur QGIS, il existe quelques problèmes connus lorsque le serveur doit charger le projet :

  • Une couche est visible dans QGIS bureautique, mais malheureusement absente dans QGIS serveur.
  • Le temps de chargement par QGIS serveur du projet est trop long.

  Ces problèmes peuvent avoir différentes sources :

  • Une couche invisible dans QGIS serveur :

    • Est-ce que le service PostgreSQL est bien configuré côté serveur ?
    • Est-ce que le fichier utilisé pour la couche (FlatGeobuf, Geotiff…) est bien accessible par le serveur avec le même chemin ?

  • Concernant le temps de chargement d'un projet, les sources sont vraiment multiples et peuvent être complexes. Certaines peuvent être simples, comme dire à QGIS d'utiliser les "métadonnées estimées" pour les couches PostgreSQL ou alors de forcer la simplification des géométries côté fournisseur de données.

  Ces problèmes sont très courants, c'est pourquoi nous avons décidé d'inclure des règles dans l'extension.

  Avec la dernière version de l'extension, vous pouvez commencer à avoir de nouvelles vérifications lors de l'enregistrement de votre fichier de configuration Lizmap. Vous pouvez également remarquer quelques mesures de protection, qui sont conçus pour vous aider à publier votre projet (en évitant certaines erreurs possibles du côté du serveur plus tard).

  

  Jetons un coup d'œil rapide à ces deux nouvelles fonctionnalités.

  Vérifications

  Avec la dernière version de l'extension Lizmap, vous pouvez remarquer un nouveau tableau lors de l'enregistrement de votre fichier de configuration.

  

  Ce tableau présente les contrôles qui ont échoué lors de la sauvegarde de la configuration.

  • Toutes les vérifications sont documentées : source de l'erreur, son nom, comment corriger l'erreur et sa gravité.
  • Certaines vérifications sont bloquantes. À l'heure actuelle, seules les vérifications qui prennent au maximum une minute à corriger sont bloquantes. Aujourd'hui, la plupart des règles bloquantes ont des outils pour auto-corriger l'ensemble du projet.

  Vous devriez quand même vous pencher sur les autres problèmes non bloquants, car certains d'entre eux réduisent les performances du serveur QGIS. Mais comme ce n'est pas une correction "clé en main", nous n'avons pas rendu ces règles bloquantes.

  Pour savoir comment résoudre le problème, passez votre souris sur la dernière colonne du tableau, une description complète apparaîtra. Ou visitez l'onglet suivant qui récapitule l'ensemble des erreurs avec les moyens pour corriger.

  Nous ajouterons également de nouvelles vérifications dans les semaines à venir.

  Mesure de protection

  Par défaut, lors de l'installation de l'extension Lizmap sur un ordinateur, vous serez considéré comme "Débutant". Ce mode est très strict sur ce que vous pouvez faire dans votre projet QGIS. Il a été principalement conçu pour une formation à Lizmap.

  Nous pensons que les utilisateurs passeront rapidement en mode "Normal", mais vous pouvez toujours modifier des paramètres dans le dernier panneau.

  Ces protections sont conçues pour vous aider. Elles permettent d'éviter que certaines couches ne puissent pas s'afficher sur Lizmap Web Client.

  

  Par exemple, si vous savez que votre serveur ne supporte pas le raster ECW, vous pouvez laisser cette case cochée.

  Notez que si vous êtes hébergé sur notre solution Lizmap Cloud, certaines protections sont configurées avec des valeurs par défaut. Par exemple, sur notre solution d'hébergement, le nombre maximum de dossiers parents autorisés lorsque vous ajoutez une couche basée sur un fichier est de deux dossiers.

  Lorsque vous êtes en mode "normal", décochez avec précaution ces cases. Certaines d'entre elles nécessitent des étapes de configuration du côté du serveur.

  Bonne mise à jour ?

• sur 3liz: Lizmap plugin 4.0.0 for QGIS Desktop

  Publié: 15 December 2023, 5:00pm CET

  New features about project validation

  When publishing a project with QGIS server, there are some known issues when the server needs to load the projet :

  • A layer can be visible in QGIS desktop, but unfortunately not visible in QGIS server.
  • The loading time of the project can be too long.

  These issues can have different sources :

  • A layer invisible in QGIS server :

    • Is the PostgreSQL service well configured on the server side ?
    • Does the file used for the layer (FlatGeobuf, Geotiff…) is readable by QGIS server with the same path ?

  • About project loading time, the source of the problem can be very different and complex. In some situations, it can be easy, like asking QGIS to use "estimated metadata" for PostgreSQL layers or also to force geometry simplification on the data provider side.

  These issues are very common, so we decided to include some rules in the plugin.

  With the latest release of the plugin, you could start seeing some new checks when saving your Lizmap configuration file. You could also notice some safeguards, which are designed to help you to publish your project (prevent some possible errors on the server side).

  

  Let's have a quick look to these two new features.

  Checks

  With the latest version of the QGIS Lizmap plugin, you could notice a new table when saving your configuration file.

  

  This table is a list of checks which have failed when saving the configuration.

  • All checks are documented : source of error, how to fix the error and its severity
  • Some checks are blocking. For now, only checks which take one minute maximum are blocking. Today, most of the blocking rules have a button to auto-fix the whole project.

  You should still have a look to other non-blocking issues, as some of them might decrease QGIS server performance. But as it's not straightforward to fix, we didn't make these rules blocking.

  To know how to fix, either put your mouse over the last column, a complete description will appear. Or visit the next tab "Help about checks", it's presenting all rules with some explanations how to fix them.

  We will add new checks in the coming weeks.

  Safeguards

  By default, when installing the Lizmap plugin on a computer, you will be considered as "Beginner". This mode is very strict about what you can do in your QGIS project. It was mainly designed for a Lizmap training.

  We guess users will quickly switch to "Normal", but you can still tweak these settings in the last panel.

  These safeguards are designed to help you. It will prevent some layers to maybe not be visible on Lizmap Web Client.

  

  If you know your server doesn't support ECW raster, you can keep this checkbox ticked.

  Note, if you are hosted on our Lizmap Cloud infrastructure, some safeguards are configured with some default values. For instance, on our hosting solution, the maximum of parent folder allowed when you add a file based layer is two folders.

  When you are in "normal" mode, please uncheck these checkbox carefully. Some of them requires some configuration steps on the server side.

  We hope you will enjoy this new version ?

• sur In Memory of Jeff Burnett

  Publié: 15 December 2023, 2:27pm CET par Simon Chester

  With great sadness, OGC announces the passing of our cherished colleague, Mr. Jeffrey Burnett of Littleton, Mass, on 28 November 2023, from cancer.

  Jeff joined OGC as Vice President for Operations and Finance in April, 2000, serving as OGC’s Chief Financial Officer and member of the Board of Directors until his retirement in 2020.  In the 20 years prior to joining OGC, Jeff held product management positions in the emerging imaging and high-performance computing market with Digital Equipment Corporation and the Massachusetts Computer Corporation (MASSCOMP). It was during this time that he first met and worked with the founders of OGC, who would later call upon Jeff to lead the Consortium’s senior staff to support OGC’s continued expansion.

  Jeff was deeply committed to OGC and proved to be incredibly talented as the Consortium’s finance lead. Jeff constantly sought ways to improve the Consortium’s approach to the fiscal and operational intricacies of OGC‘s global mission. He approached his work with professionalism, tremendously sharp wit, and a delightfully wry sense of humor – qualities appreciated by OGC Directors, Staff, and the many Member representatives he worked with.

  Jeff Burnett was a talented student and manager from the beginning of his career. Having grown up a sailor on the shores of Massachusetts Bay, Jeff was also an avid reader. He earned a bachelor’s degree in English Literature from Dartmouth College where he graduated also as a commissioned Naval officer. Upon graduation, Jeff served with honor in the U.S. Navy. A student at heart, upon returning as a reserve officer Jeff then attended Harvard University Business School where he earned his MBA. He was a patriot, a storyteller, and an avid amateur genealogist – discovering and creating lasting relationships with extended family and relatives around the world. Most importantly, Jeff was a deeply caring family man to his wife Janine, son Evan, and daughter Sarah.  

  This remarkable colleague and friend of OGC will be deeply missed.

  A formal obituary for Jeff Burnett is online here.

• sur Paul Ramsey: How to Become a CEO

  Publié: 14 December 2023, 5:00pm CET

  As a young man, I had a lot of ambition to climb the greasy pole, to get to the “top” of this heap we call a “career”, and as time went on I started doing little explorations of the career histories of people who made it to that apex corporate title, the “CEO”.

  

  It is worth doing this because, by and large, our society is run by people who either have been CEOs or who have come very close. Pull lists of boards of both private and public institutions and you will see a lot of people who have ascended to the top of large institutions before moving into governance. These are the people who determine the direction of our society, by and large.

  And how have they gotten there? Through a surprisingly small number of routes, that are all highly path dependent.

  If you spend some time exploring the employment histories of corporate leaders, you’ll find really just a couple archetypes.

  The Long-term Corporate Climber

  By far the most common pattern is for a future CEO to find an entry- or mid-level position in a large organization, and then work at that one organization for 15 to 25 years, ascending the ranks.

  

  Once they get to just below the CEO, they either leap to a CEO position at another firm, or finally ascend to the CEO position of their originating organization.

  • Darren Woods, CEO of ExxonMobile, spent 25 years working his way to the top of Exxon.
  • Ginny Rometty, former CEO of IBM, spent 25 years working her way to the top of IBM.
  • Jim Farley, CEO of Ford, actually did his important climbing (from entry level to upper management) over 17 years at Lexus, then spent another 13 years at Ford completing the climb to CEO through a sequence of high level regional jobs.
  • David Hutchens the CEO of our local gas utility, spent 26 years climbing the rungs of Tuscon Electric.

  I was spurred to write about this topic today when I learned that EDB has a new CEO (what?!), Kevin Dallas, who (wait for it), spent 24 years climbing the greasy pole at Microsoft, before being tapped for his first CEO gig in 2020.

  Speaking of Microsoft, even corporate leadership savant Satya Nadella started as an entry level engineer in Microsoft, taking the CEO slot in 2014 after 22 years of slogging upwards.

  In the main, the way to become a CEO (of a large organization) is to get yourself a job in a large organization early in your career, so you can accumulate the experience and contacts necessary to be considered a viable candidate later in your career.

  The path dependence is kind of obvious. If you spend your early career on something else, by the time you get into a large organization you will be starting too far down the heirarchy to reach the top before your career tapers off.

  To many, the surprising thing about these career profiles is how rarely there are mid-career jumps between corporations. Probably this is because people under-estimate the power of social networks.

  Your reputation for “getting things done”, the density of people who find you charming, the employees and hangers on who benefit from your rise in the organization, they are all highest in one place: the place you already work. Moving laterally in mid-career to a new organization instantly resets your accumulated social capital to zero.

  The Founder or Early Hire

  One exception to the rule is the founder of a company that grows to a scale sufficient to be considered comparable to existing institutions.

  

  This is, as you can imagine, quite rare.

  In the “wow that’s insane” founder category: Bill Gates, Steve Jobs, Mark Zuckerberg, Sara Blakely.

  Or the “locally known but still huge” founder category: Ryan Holmes (Hootsuite), Chip Wilson (Lululemon), Stewart Butterfield (Slack, Flickr), James Pattison (Pattison Group), Dennis Washington (Seaspan).

  In the tech space, there’s also a lot of early hires, who necessarily progressed quite quickly through the “ranks” as the company they had lucked into exploded in size.

  • Erik Schmidt, who rode Sun Microsystems rocket to senior management before finding CEO roles at Novell and Google.
  • Steve Balmer, who… do I need to even say?
  • Sundar Pichai, who joined Google in 2004 and held on to become CEO as the founders burned out.

  The Well Connected

  This is an interesting third category, which is difficult to join, but is very much real – knowing people who will elevate you early on.

  • Like, former Treasury Secretary Tim Geithner had on the one hand, a kind of conventional “grind it out” career working his way up the ranks of the senior federal civil service. But on the other hand, the roles he was in, right from the start were quite high level. How did he manage that? He was recommended to his first job out of college at Kissinger Associates, by the Dean of his faculty at Johns Hopkins. From there he met lots of powerful people who would vouch for his brilliance, and away he went. Now, it surely helped that he was brilliant! But, the connections were necessary too.

  • I checked out the career history of Jamie Dimon, CEO of JP Morgan, expecting to find a long slog at a major financial institution, but it turns out Dimon got an early boost into leadership, through his connection to Sandy Weill, who recruited him to American Express. And how did Weill know Dimon? Dimon’s mother knew Weill and got Dimon hired for a summer job with him. Again, it surely helped that Dimon was sharp as a tack! But, without his mom…

  

  In lots of cases, this category is fully subsumed in the first. Anyone who grinds up a corporate heirarchy will find boosters and mentors who will in turn help them get ahead. Often a senior leader gets a lot of help from a talented junior and they ascend the heirarchy in parallel. Being the “assistant to the President” might make you officially lower on the totem pole than the CFO, but unofficially and in terms of career advancement… that can be another story altogether.

  Advice?

  Despite my long-time desire to climb the greasy pole, I have never worked for an instution large enough to have any serious opportunities to climb, and have finally achieved a zen calm about career. By and large my career has been something that happened to me, not something I planned, and that colors my perceptions a lot.

  First jobs lead to first connections, and first connections determine what paths open up as you move on to second and third jobs. Path dependence in career progression is huge. Probably the most important moment is early career, getting into an institution or industry that is poised for growth and change.

  

  It’s possible to rise in an older, established institutions, but my impression is that it’s more of a knife fight. I don’t think the alternate universe Steve Balmer who started in sales at IBM would have risen to be a CEO.

  Far and away the most important thing you can amass, at any career stage, is connections. Take every opportunity to meet new people, and find people and topics that stimulate your curiosity. If what you are doing is boring or unpleasant, it’s never going to matter what your title is, or how high up the pole you are.

• sur Paul Ramsey: Keynote @ FOSS4G NA 2023

  Publié: 12 December 2023, 5:00pm CET

  Preparing the keynote for FOSS4G North America this year felt particularly difficult. I certainly sweated over it.

  • Audience was a problem. I wanted to talk about my usual thing, business models and economics, but the audience was going to be a mash of people new to the topic and people who has seen my spiel multiple times.
  • Length was a problem. Out of an excess of faith in my abilities, the organizers gave me a full hour long slot! That is a very long time to keep people’s attention and try to provide something interesting.

  The way it all ended up was:

  • Cadging some older content from keynotes about business models, to bring new folks up to speed.
  • Mixing in some only slightly older content about cloud models.
  • Adding in some new thoughts about the way everyone can work together to make open source more sustainable (or at least less extractive) over the long term.

  Here’s this year’s iteration.

  The production of this kind of content is involved. The goal is to remain interesting over a relatively long period of time.

  I have become increasingly opinionated about how to do that.

  • No freestyling. Blathering over bullet points is unfair to your audience. The aggregate time of an audience of 400 is very large. 5 minutes of your “um” and “ah” translates into 33 hours of dead audience time.
  • Get right to it. No mini-resume, no talking about your employer (unless you are really sneaky about it, like me ?), this is about delivering ideas and facts that are relevant to the audience. Your introducer can handle your bona fides.
  • Have good content. The hardest part! (?) Do you have something thematic you can bookend the start and end with? Are there some interesting facts that much of the audience does not know yet? Are there some unappreciated implications? This is, presumably, why you were asked to keynote, so hopefully not too, too hard. This is the part that I worry over the most, because I really have no faith that what I have to say is actually going be interesting to an audience, no matter how much I gussy it up.
  • Work from a text. The way to avoid blather is to know exactly what you are going to say. At 140 words-per-minute speaking pace, a 55 minute talk is 7700 words, which coincidentally (not) is exactly how long my keynote text is.
  • Write a speech, not an article. You will have to say all those words! Avoid complicated sentence constructions. Keep sentences short. Take advantage of parallel constructions to make a point, drive a narrative, force a conclusion. (see?) Repeat yourself. Repeat yourself.
  • Perform, don’t read. Practice reading out loud. Get used to leaving longer gaps and get comfortable with silence. Practice modulating your voice. Louder, softer. Faster, slower. Drop. The. Hammer. Sometimes. Watch a gifted speaker like Barack Obama deliver a text. He isn’t ad libbing, he’s performing a prepared text. See what he does to make that sound spontaneous and interesting.
  • Visuals as complements, not copies. Your slides should complement and amplify your content, not recapitulate it. In the limit, you could do all-text slides, which just give the three-word summary of your current main point. (This classic Lessig talk is my favourite example.)
  • Visuals as extra channel. Keep changing up the visual. Use the slide notes space to get a feel for how long each slide should be up. (Hint, about 50 words on average.) Keeping slide duration low also helps in terms of using the per-slide speaker notes as low-end teleprompter (increase notes font size! reduce slide preview size!) from which you deliver your performance.

  I originally started scripting talks because it allowed me to smooth out the quality of my talks. With a script, it wasn’t a crapshoot whether I had a good ad lib delivery or a bad one, I had a nice consistent level. From there, leveraging up to take advantage of the format to increase the talk quality was a natural step. Speakers like Lessig and Damian Conway remain my guide posts.

  Con enorme alegría anunciamos el cierre de una edición más (la sexta) del Curso–Concurso Geoalfabetización mediante la utilización de Tecnologías de la Información Geográfica.

  ¿De qué se trata todo esto? Es la culminación de una iniciativa que nace en 2010 para desarrollar gvSIG Batoví.

  

  ¿Y qué es gvSIG Batoví? Es un SIG (Sistema de Información Geográfica) aplicado a entornos educativos, con destino al Ceibal (proyecto para Uruguay de la iniciativa OLPC/OneLaptopPerChild), y en base al software libre de origen español gvSIG

  estudiantes utilizando gvSIG Batoví en las aulas

  ¿Por qué hacer ésto? Se trata de una iniciativa de la Dirección Nacional de Topografía (Ministerio de Transporte y Obras Públicas/MTOP-Uruguay) como aporte a la enseñanza desde un área de su conocimiento. La Dir. Nac. de Topografía promueve y es parte de la IDEuy (Infraestructura de Datos Espaciales de Uruguay), a la vez que desarrolla y es responsable del Geoportal del MTOP.

  

  ¿Cómo nace? Se firma un convenio entre el MTOP, Ceibal y la Asociación gvSIG (año 2011) para adaptar gvSIG a los dispositivos de Ceibal, obteniendo una primera versión en agosto de 2012.

  

  A partir de ahí se plantea una amplia Estrategia de Sostenibilidad:

  • espacio dentro del Portal Ceibal

  

  • blog del proyecto dentro de Ceibal

  

  • lista de correo

  

  • difusión internacional: presentaciones en numerosos congresos, artículos en publicaciones extranjeras, participación en proyectos académicos mundiales, exposición en hall de sede de las Naciones Unidas (Nueva York), invitación a ser parte de GeoForAll (Comité de divulgación educativa de la Open Source Geospatial Foundation/OSGeo)

  exposición de posters en las Naciones Unidas (Nueva York) en ocasión del International Map Year

  • talleres nacionales a maestros, profesores, estudiantes de profesorado, estudiantes liceales

• sur Free and Open Source GIS Ramblings: Mapping relationships between Neo4j spatial nodes with GeoPandas

  Publié: 9 December 2023, 10:33pm CET

  Previously, we mapped neo4j spatial nodes. This time, we want to take it one step further and map relationships.

  A prime example, are the relationships between GTFS StopTime and Trip nodes. For example, this is the Cypher query to get all StopTime nodes of Trip 17:

  MATCH 
      (t:Trip  {id: "17"})
      <-[:BELONGS_TO]-
      (st:StopTime) 
  RETURN st
  

  

  To get the stop locations, we also need to get the stop nodes:

  MATCH 
      (t:Trip {id: "17"})
      <-[:BELONGS_TO]-
      (st:StopTime)
      -[:STOPS_AT]->
      (s:Stop)
  RETURN st ,s
  

  

  Adapting our code from the previous post, we can plot the stops:

  from shapely.geometry import Point
  
  QUERY = """MATCH (
      t:Trip {id: "17"})
      <-[:BELONGS_TO]-
      (st:StopTime)
      -[:STOPS_AT]->
      (s:Stop)
  RETURN st ,s
  ORDER BY st.stopSequence
  """
  
  with driver.session(database="neo4j") as session:
      tx = session.begin_transaction()
      results = tx.run(QUERY)
      df = results.to_df(expand=True)
      gdf = gpd.GeoDataFrame(
          df[['s().prop.name']], crs=4326,
          geometry=df["s().prop.location"].apply(Point)
      )
  
  tx.close() 
  m = gdf.explore()
  m
  

  

  Ordering by stop sequence is actually completely optional. Technically, we could use the sorted GeoDataFrame, and aggregate all the points into a linestring to plot the route. But I want to try something different: we’ll use the NEXT_STOP relationships to get a DataFrame of the start and end stops for each segment:

  QUERY = """
  MATCH (t:Trip {id: "17"})
     <-[:BELONGS_TO]-
     (st1:StopTime)
     -[:NEXT_STOP]->
     (st2:StopTime)
  MATCH (st1)-[:STOPS_AT]->(s1:Stop)
  MATCH (st2)-[:STOPS_AT]->(s2:Stop)
  RETURN st1, st2, s1, s2
  """
  
  from shapely.geometry import Point, LineString
  
  def make_line(row):
      s1 = Point(row["s1().prop.location"])
      s2 = Point(row["s2().prop.location"])
      return LineString([s1,s2])
  
  with driver.session(database="neo4j") as session:
      tx = session.begin_transaction()
      results = tx.run(QUERY)
      df = results.to_df(expand=True)
      gdf = gpd.GeoDataFrame(
          df[['s1().prop.name']], crs=4326,
          geometry=df.apply(make_line, axis=1)
      )
  
  tx.close() 
  gdf.explore(m=m)
  

  

  Finally, we can also use Cypher to calculate the travel time between two stops:

  MATCH (t:Trip {id: "17"})
     <-[:BELONGS_TO]-
     (st1:StopTime)
     -[:NEXT_STOP]->
     (st2:StopTime)
  MATCH (st1)-[:STOPS_AT]->(s1:Stop)
  MATCH (st2)-[:STOPS_AT]->(s2:Stop)
  RETURN st1.departureTime AS time1, 
     st2.arrivalTime AS time2, 
     s1.location AS geom1, 
     s2.location AS geom2, 
     duration.inSeconds(
        time(st1.departureTime), 
        time(st2.arrivalTime)
     ).seconds AS traveltime
  

  

  As always, here’s the notebook: [https:]]

  PostGIS Day 2023 videos came out recently. PostGIS Day conference is always my favorite conference of the year because you get to see what people are doing all over the world, and it always has many many new tricks for using PostgreSQL and PostGIS family of extensions you had never thought of. Most importantly it's virtual, which makes it much easier for people to fit in their schedules than an on site conference. We really need more virtual conferences in the PostgreSQL community. Many many thanks to Crunchy Data for putting this together again, in particular to Elizabeth Christensen who did the hard behind the scenes work of corraling all the presenters and stepping in to give a talk herself, and my PostGIS partner in development Paul Ramsey who did the MC'ing probably with very little sleep, but still managed to be very energetic. Check out Elizabeth's summary of the event. Many of her highlights would have been mine too, so I'm going to skip those.

• sur Jackie Ng: Announcing: mapguide-rest 1.0 RC6

  Publié: 4 December 2023, 11:30am CET

  6 years later, I have finally put out another release of mapguide-rest!

  The reason for finally putting out a new release (besides being long overdue!), is that I needed a solid verification of the vanilla SWIG API binding work for MapGuide Open Source 4.0 and mapguide-rest was just the ideal project that touches almost every nook and cranny of the MapGuide API. So if mapguide-rest still works with the PHP binding in MapGuide Open Source 4.0, that is as good of an endorsement to the reliability and readiness of these bindings.

  For this release of mapguide-rest, it is compatible with the version of PHP that comes with:

  • MapGuide Open Source 3.1.2 (PHP 5.6)
  • MapGuide Open Source 4.0 Beta 1 (PHP 8.1)

  Besides being compatible with the upcoming MapGuide Open Source release (and the current stable one), this release also adds a new series of APIs to perform various geo-processing tasks. All of which are available to try out in the interactive swagger API reference.
  
  
  Download
  Special thanks to Gordon Luckett and Scott Hamiester for assistance in internal testing of many internal builds of mapguide-rest that finally culminated in this long-overdue release.
  Now that this is out of the way, it is back to MapGuide development proper and getting closer to the 4.0 release.

• sur From GIS to Remote Sensing: Tutorial: Using Remotior Sensus in Copernicus JupyterLab

  Publié: 3 December 2023, 3:50pm CET

  This is a tutorial about Remotior Sensus, a Python package that allows for the processing of remote sensing images and GIS data.
  In particular, this tutorial describes the use of Remotior Sensus in Copernicus JupyterLab, which is a Jupyter Notebook service in a web-based environment, offering several tools for working with the Copernicus Data Space.This service can be accessed at this link [https:]]  after a free registration to the Copernicus Data Space Ecosystem (CDSE).
  The Jupyter Notebooks are available in 3 flavors: Small (2 CPU cores and 4GB RAM), Medium (2 CPU cores and 8GB RAM) and Large (4 CPU cores and 16GB RAM). As stated in the documentation, to ensure the fair use of resources by the CDSE users, it is recommended to start with the Small flavor and switch to a bigger only in case of issues with kernel crashing due to the lack of available memory.
  Therefore, the Copernicus JupyterLab offers a great opportunity to use Copernicus data in a cloud environment. In this tutorial, we are going to see how to:

  • Download and preprocess Sentinel-2 images.
  • Create a BandSet and prepare a training input
  • Run a Random Forest classification

  All the above steps are performed in the cloud. The classification output is saved in a persistent storage with 10GB of space and can be downloaded later. Read more »

• sur Free and Open Source GIS Ramblings: Mapping Neo4j spatial nodes with GeoPandas

  Publié: 3 December 2023, 2:31pm CET

  In the recent post Setting up a graph db using GTFS data & Neo4J, we noted that — unfortunately — Neomap is not an option to visualize spatial nodes anymore.

  GeoPandas to the rescue!

  But first we need the neo4j Python driver:

  pip install neo4j
  

  Then we can connect to our database. The default user name is neo4j and you get to pick the password when creating the database:

  from neo4j import GraphDatabase
  
  URI = "neo4j://localhost"
  AUTH = ("neo4j", "password")
  
  with GraphDatabase.driver(URI, auth=AUTH) as driver:
      driver.verify_connectivity()
  

  Once we have confirmed that the connection works as expected, we can run a query:

  QUERY = "MATCH (p:Stop) RETURN p.name AS name, p.location AS geom"
  
  records, summary, keys = driver.execute_query(
      QUERY, database_="neo4j",
  )
  
  for rec in records:
      print(rec)
  

  

  Nice. There we have our GTFS stops, their names and their locations. But how to put them on a map?

  Conveniently, there is a to_db() function in the Neo4j driver:

  import geopandas as gpd
  import numpy as np
  
  with driver.session(database="neo4j") as session:
      tx = session.begin_transaction()
      results = tx.run(QUERY)
      df = results.to_df(expand=True)
      df = df[df["geom[].0"]>0]
      gdf = gpd.GeoDataFrame(
          df['name'], crs=4326,
          geometry=gpd.points_from_xy(df['geom[].0'], df['geom[].1']))
      print(gdf)
  
  tx.close() 
  

  Since some of the nodes lack geometries, I added a quick and dirty hack to get rid of these nodes because — otherwise — gdf.explore() will complain about None geometries.

  

  You can find this notebook at: [https:]]

  Next step will have to be the relationships. Stay posted.

• sur How OGC Contributes to FAIR Geospatial Data

  Publié: 30 November 2023, 6:39pm CET par Simon Chester

  Standards are a key element of the FAIR Principles of Findability, Accessibility, Interoperability, and Reusability. As such, the Open Geospatial Consortium (OGC) has been supporting the FAIR Principles for geospatial information since its formation 30 years ago.

  Following the more recent codification of the FAIR principles, the growing recognition of their potential to improve data production, storage, exchange, and processing is seeing them being used to support and enhance recent technological developments such as artificial intelligence, crowdsourcing, data spaces, digital twins, cloud computing, and beyond. This blog post, therefore, offers an overview of select OGC standards and components that support FAIRness in geospatial data.

  Within the whole OGC Standards suite, we can broadly distinguish two types of Standards: data format and transfer standards that facilitate data exchange between systems; and semantic interoperability standards that support a common understanding of the meaning of data. For example, OGC Standards that define interoperable geometrical information formats, such as 3D Tiles, GML, GeoPackage, GeoTiff, or KML, support FAIRness by facilitating data Access and Reuse.

  Communication Standards

  Starting with OGC Web Map Service (WMS) 1.0 in 2000, the suite of OGC Web Services Standards grew to become OGC’s most popular and successful suite of Standards. Services that implement OGC Web Services Standards give access to different kinds of data through the web. Most OGC Web Services provide instructions on how to post a message or build a query URL that gives access to the data behind the service. The URL contains an action to perform and parameters to modify the action and specify the form of the result.

  While perfectly functional, the OGC Web Services Standards do not completely follow modern practices on the Web. In particular they do not focus on resources but on operations. To correct that issue, the OGC is evolving the OGC Web Services into the OGC APIs – open web APIs that define resources and use HTTP methods to retrieve them. OGC APIs have diverse functionalities, as explained below.

  Communication Standards for Finding Data

  The Catalog Service for the Web (CSW) is an OGC Web Service that provides the capacity to query a collection of metadata and find the data or the services that the user requires. Deploying a CSW (e.g. a GeoNetwork instance) is a way to comply with the FAIR sub-principle “F4. (Meta)data are registered or indexed in a searchable resource.” CSW is compatible with Dublin Core and ISO 19115 metadata documents. An interesting characteristic of the GeoNetwork is its capability to store attachments to the metadata. This provides a way to store the actual data as an attachment and link it to the distribution section of an ISO 19115. This ensures not only Findability of the metadata but also Findability of the data. In the Open Earth Monitor (OEMC) project, CSW can be effectively used to store metadata about the in-situ data and some of the results of the pilots, making them Findable on the web. The original Remote Sensing data is offered through a SpatioTemporal Asset Catalog (STAC).

  The OGC API – Records Standard is an alternative to CSW that uses the aforementioned resource-oriented architecture. It gives a URL to each and every metadata/data record stored in the catalog, making it compliant with the FAIR sub-principle “F1. (Meta)data are assigned a globally unique and persistent identifier.” The OGC API – Records Standard is still in its draft phase and the authors are making efforts to exploit STAC good practices and make the two compatible. 

  For flexibility, in the CSW and OGC API – Records Standards, a metadata record is not obligatory, though it is desirable in many cases. This is useful for improved findability, but also for preservation purposes when the dataset may no longer be available. This ensures compatibility with the FAIR sub-principle “A2. Metadata are accessible, even when the data are no longer available.”

  Communication Standards for Accessing Data

  The OGC Web Feature Service (WFS) and the Web Coverage Service (WCS) give access to feature or coverage data independently of the data’s data model or schema. Implementations of these services are based on Open Standards that can be implemented for free. This complies with the FAIR sub-principle “A1.1 The protocol is open, free, and universally implementable.” It is possible to get the whole resource or a subset of it based on spatial or thematic queries. However, these services are based on a service-oriented architecture and do not necessarily provide a URI for each resource. 

  The newer OGC API – Features and OGC API – Coverages Standards, though, provide similar functionality with a resource-oriented architecture. They provide a URI for each resource they expose. This makes the OGC API Standards, as well as the SensorThings API, compliant to the FAIR sub-principle “A1. (Meta)data are retrievable by their identifier using a standardized communications protocol.” OGC Web Services and OGC APIs both use the HTTP protocol over the Internet and can make use of the current standards and practices for authentication and authorization, such as OpenID Connect. 

  However, the resource-oriented architecture of the OGC API Standards means they are better positioned to adopt best practices for authentication and authorization. In this paradigm, authorization on geospatial resources can be fine-tuned for each resource URI in the same way as any other resource on the Web. As such, OGC API – Features, OGC API – Coverages, and The Sensor Things API comply with the FAIR sub-principle “A1.2 The protocol allows for an authentication and authorization procedure, where necessary.”

  Semantic Interoperability Standards The OGC RAINBOW

  To better support the “Interoperable” FAIR principle as it applies semantic interoperability, OGC is implementing the OGC RAINBOW (formerly the OGC Definitions Server) as a Web accessible source of information about concepts and vocabularies that OGC defines or that communities ask the OGC to host on their behalf. It applies FAIR principles to the key concepts that underpin interoperability in systems using OGC specifications.

  The OGC Registry for Accessible Identifiers of Names and Basic Ontologies for the Web (RAINBOW) is a linked-data server, published and maintained by OGC, used to manage and publish reference vocabularies, standard definitions with profiles, ontologies, and resources. It is intended to be a node in an interoperable ecosystem of resources published by different communities. It supports a wide spectrum of resources and allows more value to be realized from data. It can be accessed at opengis.net/def.

  OGC RAINBOW is implemented using Linked Data principles that provide enhanced findability, making it compliant with the FAIR sub-principles “F1. (Meta)data are assigned a globally unique and persistent identifier” and “F4: (Meta)data are registered or indexed in a searchable resource.”  It is accessed using the HTTP protocols over the Internet, so is also compliant with “A1. (Meta)data are retrievable by their identifier using a standardised communication protocol” and “A1.1 The protocol is open, free, and universally implementable.”

  The set of concepts stored in the RAINBOW or in other vocabularies can be used by data and metadata to comply with the FAIR sub-principles “I1. (Meta)data use a formal, accessible, shared, and broadly applicable language for knowledge representation” and “I2. (Meta)data use vocabularies that follow FAIR principles.” 

  The OGC SensorThings API

  The OGC SensorThings API is an open and free standard that complies to the FAIR sub-principle “A1.1 The protocol is open, free, and universally implementable.” It incorporates a data model that includes two properties that allow for linking to URLs for “units of measurement” and “observed properties” (e.g. references to variable definitions) that makes it compliant with the FAIR sub-principle “I2. (Meta)data use vocabularies that follow FAIR principles.” However, other services and APIs, such as OGC API – Features and OGC API – Coverages, do not specify how this could be done in practice, so more work needs to be done in that respect. 

  On the other hand, the new OGC APIs use link mechanisms to connect datasets, resources, and resource collections to other resources for different purposes, making them compliant with the FAIR sub-principle “I3 (Meta)data include qualified references to other (meta)data.” 

  Similarly, the new OGC SensorThings API plus (STAplus) Standard includes an additional element called “Relation” that allows for relating an observation to other internal or external observations. It also adds an element called “License” associated with the datastream or observation group that complies with the FAIR sub-principle “R1.1. (Meta)data are released with a clear and accessible data usage license.” Further, the STA data model can be extended to domain-specific areas by subclassing some of the entities, such as “Thing” and “Observation,” allowing it to meet the FAIR sub-principle “R1.3. (Meta)data meet domain-relevant community standards.” 

  STAplus includes many considerations for secure operations and can support authentication and authorization through the implementation of business logic, making it compliant with the FAIR sub-principle “A1.2. The protocol allows for an authentication and authorization procedure where necessary.”

  Other Standard Thematic Data Models

  OGC also offers Standards that define thematic data models and knowledge representations. For example, WaterML is an information model for the representation of water observations data. In addition, PipelineML defines concepts supporting the interoperable interchange of data pertaining to oil and gas pipeline systems. The PipelineML Core addresses two critical business use-cases that are specific to the pipeline industry: new construction surveys and pipeline rehabilitation. 

  Another example is the Land and Infrastructure Conceptual Model (LandInfra) for land and civil engineering infrastructure facilities. Subject areas include facilities, projects, alignment, road, railway, survey, land features, land division, and “wet” infrastructure (storm drainage, wastewater, and water distribution systems). CityGML is intended to represent city objects in 3D city models. The (upcoming) Model for Underground Data Definition and Integration (MUDDI) represents information about underground utilities. IndoorGML offers a data model to represent indoor building features. Finally, GeoSciML is a model of geological features commonly described and portrayed in geological maps, cross sections, geological reports and databases. This standard describes a logical model for the exchange of geological map data, geological time scales, boreholes, and metadata for laboratory analyses. 

  The existence of these Standards can help each thematic sector to comply with the FAIR Interoperability sub-principle “I1. (Meta)data use a formal, accessible, shared, and broadly applicable language for knowledge representation.” As well as these standards, connecting their vocabularies to information systems or databases would significantly increase their usefulness and encourage the principle of Reusability “R1.(Meta)data are richly described with a plurality of accurate and relevant attributes” and sub-principle “R1.3 (Meta)data meet domain-relevant community standards.”

  FAIR in Everything We Do

  OGC’s Mission, to “Make location information Findable, Accessible, Interoperable, and Reusable (FAIR),” places the FAIR Principles at the heart of everything we do. This post has shown how OGC Standards explicitly address the FAIR Principles to contribute to FAIR geospatial data. 

  The Standards shown here were chosen due to their popularity and utility, but represent only a small portion of what’s available from OGC. You can see the full suite of OGC Standards at ogc.org/standards.

  GeoServer installation methods: “Windows Installer” and “Web Archive”

  GeoServer installation methods: “Windows Installer” and “Web Archive” In this session, we will talk about how to install GeoServer software by two common methods in Windows. If you want to access the complete tutorial, simply click on the link.

  

  Introduction

  GeoServer can be installed on different operating systems, since it’s a Java based application. You can run it on any kind of operating system for which exists a Java virtual machine. GeoServer’s speed depends a lot on the chosen Java Runtime Environment (JRE). The latest versions of GeoServer are tested with both OracleJRE and OpenJDK. These versions are:

  • Java 17 for GeoServer 2.23 and above
  • Java 11 for GeoServer 2.15 and above
  • Java 8 for GeoServer 2.9 to GeoServer 2.22
  • Java 7 for GeoServer 2.6 to GeoServer 2.8
  • Java 6 for GeoServer 2.3 to GeoServer 2.5
  • Java 5 for GeoServer 2.2 and earlier

  But remember that the older versions are unsupported and won’t receive fixes nor security updates, and contain well-known security vulnerabilities that have not been patched, so use at own risk. That is true for both GeoServer and Java itself.

  There are many ways to install GeoServer on your system. This tutorial will cover the two most commonly used installation methods on Windows.

  • Windows Installer
  • Web Archive

  Windows installer

  The Windows installer provides an easy way to set up GeoServer on your system, as it requires no configuration files to be edited or command line settings.

  Installation

  • GeoServer requires a Java environment (JRE) to be installed on your system, available from Adoptium for Windows Installer, or provided by your OS distribution. For more information, please refer to this link: [https:]

  Consider the operating system architecture and memory requirements when selecting a JRE installer. 32-bit Java version is restricted to 2 GB memory, while the 64-bit version is recommended for optimal server memory. Utilizing JAI with the 32-bit JRE can enhance performance for WMS output generation and raster operations.

  • Install JRE by following the default settings and successfully complete the installation.
  • Navigate to the GeoServer.org and download the desired version of GeoServer.
  • Launch the GeoServer installer and agree to the license.
  • Enter the path to the JRE installation and proceed with the installation. The installer will attempt to automatically populate this box with a JRE if it is found, but otherwise you will have to enter this path manually.
  • Provide necessary details like the GeoServer data directory, administration credentials, and port configuration.
  • Review the selections, install GeoServer, and start it either manually or as a service.
  • Finally, navigate to localhost:8080/geoserver (or wherever you installed GeoServer) to access the GeoServer Web administration interface.

  Uninstallation

  GeoServer can be uninstalled in two ways:

  • By running the uninstall.exe file in the directory where GeoServer was installed
  • By standard Windows program removal

  Web Archive

  GeoServer is packaged as a web-archive (WAR) for use with an application server such as Apache Tomcat or Jetty. It has been mostly tested using Tomcat, and so is the recommended application server. There are reasons for installing it such as it is widely used, well-documented, and relatively simple to configure. GeoServer requires a newer version of Tomcat (7.0.65 or later) that implements Servlet 3 and annotation processing. Other application servers have been known to work, but are not guaranteed.

  Installation

  • Make sure you have a JRE installed on your system, then download Apache Tomcat from its website [https:] For the Windows installation package, scroll down and choose the 32bit/64bit Windows Service Installer option.
  • Configure Tomcat by selecting components, setting up a username and password, and specifying memory settings. So, before start the Tomcat service, you have to configure the memory settings that will use for Java VM. To do it, open the Tomcat9w from the bin folder, then click on the Java tab. This tab allows for configuration of memory settings, including initial and maximum memory pool sizes. Recommended values are 512MB for the initial memory pool and 1024MB for the maximum memory pool.
  • Start Tomcat service and verify its functionality, then navigate to localhost:8080, and get the Tomcat9 web page.
  • Navigate to the GeoServer.org and Download page. Select Web Archive on the download page from the version of GeoServer that you wish to download.
  • Deploy the GeoServer web archive as you would normally. Often, all that is necessary is to copy the GeoServer.war file to the Tomcat’s webapps directory, then the application will be deployed automatically.
  • Now to access the Web administration interface, open a browser and navigate to localhost:8080 and press Manager App button. Enter the username and password of apache tomcat. Click on the start button for the GeoServer. Once it has started, click the GeoServer link. This will take you to the GeoServer web page.

  Uninstallation

  Stop the container application. Remove the GeoServer webapp from the container application’s webapps directory. This will usually include the GeoServer.war file as well as a GeoServer directory.

  Difference between GEOSERVER.war and GEOSERVER.exe?

  • The ‘GeoServer.exe’ NSIS installer registers GeoServer as a Windows Service, which uses the Jetty application server to run GeoServer. The ‘GeoServer.war’ is a platform independent web-archive package to be deployed in your own application server (we recommend Apache Tomcat). Using the ‘GeoServer.exe’ installer is a reliable way to setup GeoServer as a windows background service. The downside is the included Jetty application server is managed using text files (jetty.ini) once installed.
  • Use of ‘GeoServer.war’ web-archive is provided to install into your own application server (we recommend Apache Tomcat as the market leader, with excellent documentation and integration options). A single application server may support several web application allowing GeoServer to be run alongside your own java web application.

• sur gvSIG Team: Free workshop on ‘Introduction to gvSIG,’ using version 2.6 and its new icon set at 19th gvSIG Conference

  Publié: 28 November 2023, 3:47pm CET

  On November 30, 2023, during the 19th International gvSIG Conference, a free workshop will be held to learn to use version 2.6 of gvSIG, showcasing the new icon set.

  To participate in the workshop, simply register using the following link: Workshop Registration.

  

  Version 2.6 comes with an improved default icon set, replacing the one used since its initial versions.

  This workshop will cover the main tools of the application, creating views, loading vector and raster layers, both locally and remotely, editing them graphically and alphanumeric, applying geoprocessing, and creating maps. All of this will be done using the new icon set, providing a refreshed version of gvSIG.

  Whether you’ve used gvSIG before or it’s your first time, you won’t want to miss this workshop.

  To follow it, you’ll need to download the portable version 2.6 of gvSIG for your operating system: Windows 64 – Windows 32 – Linux 64 – Linux 32

  You’ll have to extract it to a folder without spaces. For example, you can create a folder called ‘gvSIG’ in C:\ (on Windows) or in the user’s home directory (on Linux), place the zip file inside, and extract it there.

  You’ll also need to download the cartography to be used: Workshop Cartography ‘Introduction to gvSIG 2.6’
