    • sur Mappery: Redlining

      Publié: 12 December 2024, 11:00am CET

      I spotted this map in Franklin Delano Roosevelt Museum, which had a special exhibition on FDR and Black African Americans.

      Redlining Map of Poughkeepsie, New York and its Suburbs, March 1938
      This redlining map of Poughkeepsie was among the hundreds of “Residential Security Maps” of urban areas created by the Home Owners’ Loan Corporation.

      The maps indicated mortgage lending risk by neighborhood type, including residential, commercial, and industrial areas. Residential districts were marked with different colors to indicate the level of risk in mortgage lending. Streets and neighborhoods that included minority (especially African American) and immigrant populations were often marked in RED as “Fourth Grade” or “Hazardous”— the riskiest category for federally insured homeowner loans. For example, in the BLUE area marked B3 on this map there is a small sliver of RED along Glenwood Avenue. Notes that accompany the map explain why: “Glenwood Avenue, which is shown in red, was an old Negro settlement before this area was built up.” Similarly, in the BLUE area marked B2 Pershing Avenue appears in RED. The mapmaker’s notes indicate: “Pershing Avenue (marked in red) has a number of negro families. Houses on this street are very poor and of little value.”

      Not a lot seems to have changed!

      Cet article concerne des fonctionnalités en cours de développement et sujettes à évolution.

      Dans le cadre du développement du mode globe de Giro3D (voir notre article à ce sujet), voyons de plus près les effets atmosphériques proposés en complément de la nouvelle entité Globe: Glow, Atmosphere et SkyDome.

      ? Ces trois entités sont totalement indépendantes de l’entité Globe (et de toutes les autres entités de Giro3D) et peuvent donc être utilisées dans des scènes ne comportant aucun globe (par exemple en remplaçant les globes par de simples sphères colorées).

      L’entité Glow

      Cette entité permet de représenter un simple halo lumineux sphérique. Il permet de représenter un objets émettant de la lumière (comme le Soleil), ou bien une atmosphère très simplifiée (en terme de puissance de calcul graphique requise). Elle n’est pas sensible à l’éclairage de la scène.

      const SUN_RADIUS = 696_340_000;

const glow = new Glow({
    color: '#ff7800',
    ellipsoid: Ellipsoid.sphere(SUN_RADIUS),
});

      Le globe du soleil seul

      Le halo du soleil seul

      Le halo du soleil seul

      Globe et halo combinés

      L’entité Atmosphere

      Cette entité permet de représenter fidèlement une atmosphère vue de l’espace. Elle requiert une position du soleil pour fonctionner, via la méthode Atmosphere.setSunPosition().

      const atmosphere = new Atmosphere({ ellipsoid: Ellipsoid.WGS84 });

const sunLatitude = 5;
const sunLongitude = 45;

const sunPosition = Ellipsoid.WGS84.toCartesian(
    sunLatitude,
    sunLongitude,
    50_000_000,
);

atmosphere.setSunPosition(sunPosition);
      Création d'une atmosphère autour de la terre L'entité Atmosphere combinée à une simple sphère bleue

      Une fois combiné avec un Globe paramétré avec des couches images appropriées, voici le résultat:

      Globe terrestre et atmosphère combinés

      Globe terrestre et atmosphère combinés

      L’entité SkyDome

      Cette dernière entité est le pendant de l’entité Atmosphere, mais vu depuis l’intérieur. Elle permet de représenter la diffusion Rayleigh, c’est à dire la diffusion des rayons du soleil dans le ciel (ce qui donne sa couleur au ciel). Le disque solaire est également représenté avec fidélité selon la position apparente du soleil par rapport à l’horizon.

      const skyDome = new SkyDome();
instance.add(skyDome);

atmosphere.setSunPosition(sunPosition);

      Conclusion

      Combinées aux éclairages dynamiques et aux ombres portées, ces trois nouvelles entités permettront aux utilisateurs de créer de belles scènes réalistes, de l’échelle locale à celle du système solaire.

      Publié: 10 December 2024, 1:00pm CET

      WebGIS é uma tecnologia usada para exibir e analisar dados espaciais na Internet. Ele combina as vantagens da Internet e do GIS oferecendo um novo meio de acessar informações espaciais sem a necessidade de você possuir ou instalar um software GIS.

      A necessidade de divulgação de dados geoespaciais têm estimulado cada vez mais o uso de ferramentas WebGIS para apresentações interativas de mapas e de informações relacionadas por meio da internet.

      As soluções adotadas na apresentação destes mapas devem apresentar um equilíbrio entre facilidade de uso, riqueza de recursos para visualização e navegação entre os dados, e funcionalidades geoespaciais para pós processamento, características que devem ser adequadas para cada perfil de usuário que acessará o WebGIS.

      Se você e sua empresa possuem dados geoespaciais e querem disponibilizá-las na Web, o caminho natural para isso é o desenvolvimento de um WebGIS. Mas, se você não tiver uma equipe de TI, ou um especialista em desenvolvimento GIS, não se preocupe, a Geocursos pode te ajudar.

      Nossa experiência em GIS nos habilita a entregar soluções baseadas nessa tecnologia utilizando ferramentas open source de visualização geográfica aliada a soluções criativas para o seu negócio.

    • sur Sean Gillies: Late fall biking

      Publié: 8 December 2024, 4:55am CET

      I've decided to try to ride a bike for exercise more in 2025. Run harder, but run less, with more active recovery and low-intensity outings on a bike. At least until June, when I need to start building the running and hiking endurance that I will need in September.

      I got a new bike to make this more fun. It's a Rocky Mountain Solo C50 and I bought it from my favorite local bike shop, Drake Cycles, last Saturday. The first thing I did was pedal it from home up Spring Creek Trail to Pineridge Open Space and ride some laps around the pond. It sure beats riding my commuter bike on dirt and gravel. I haven't bought a new bike or any new bike components in 10 years. Electronic shifters feel like magic to me.

      A dark blue-green bike with wide drop handlebars leaning on an interpretive sign in a dry valley under and overcast sky.

      So far this week I've done two rides from the barn where we keep our horses while Bea has been doing her equestrian stuff. One at sunset and one at sunrise. I've been three miles east of the barn and seven miles north of the barn, following roads on the PLSS section grid.

      https://live.staticflickr.com/65535/54189616674_92bf31726f_b.jpg

      A dirt road at dusk, headlights of an approaching truck, and orange sunset glow behind the Rocky Mountains.

      In the neighborhood of the barn, the ground is completely free of snow and quite dry. Passing trucks raise medium density clouds of dust. There are scattered homes out here, and vehicles going to and fro periodically. There are large construction sites, too, which can mean a wave of large rigs pulling trailers.

      A rolling dirt road and brown grassland with snow-dusted mountains in the background.

      I've got a lot to learn about this kind of riding. The right tire pressure for road and trail conditions, for example, and how to get in and out of the drops smoothly. How to descend and corner safely, and how to survive washboard surfaces. Dressing, too. I'm riding at a low intensity and don't generate as much heat as I do when I run.

      One of my favorite things about riding further east is the panoramic views of the Front Range peaks. I can see Pikes Peak, Mount Evans, Longs Peak, and the Mummy Range, a span of 200 kilometers, from the top of every rise.

    • sur Sean Gillies: Productive running

      Publié: 7 December 2024, 9:53pm CET

      At last, I'm less than 1% injured and am getting back into regular and productive running. We've had a long stretch of mild and dry weather here, which makes it easy to just lace up and go. I ran four times last week, including a nice hilly run in Lory State Park, and will run three times this week. Thursday I did some harder running and a bunch of strides for the first time since June.

      Some faint numbness lingers on my left quad, but my hip, butt, and leg are otherwise just fine. My doctor prescribed a course of prednisolone in early November to calm down my pinched nerve and that seemed to banish the last of my Achilles tendonitis as well. My right heel and calf haven't been pain-free in a long time. It's really nice to feel good.

    • sur Fernando Quadro: 10 aplicações GIS em Energias Renováveis

      Publié: 5 December 2024, 1:00pm CET

      À medida que o mundo transita para um futuro energético mais limpo e sustentável, o papel dos Sistemas de Informação Geográfica (GIS) se tornou indispensável.

      O GIS nos permite enfrentar os desafios complexos do desenvolvimento de energia renovável com precisão e eficiência.

      Seja identificando os principais locais para fazendas solares, avaliando o potencial de energia eólica ou planejando infraestrutura hidrelétrica, o GIS fornece os insights espaciais necessários para tomar decisões informadas.

      Além do planejamento de projetos, o GIS oferece suporte a avaliações ambientais, mitiga riscos e ajuda a integrar energia renovável em redes elétricas, garantindo que esses desenvolvimentos sejam sustentáveis e resilientes.

      Ele também capacita provedores de energia e formuladores de políticas a envolver comunidades, reduzir emissões e enfrentar as mudanças climáticas de frente.

      Aqui estão 10 maneiras principais pelas quais o GIS está moldando o setor de energia renovável, promovendo inovação e impulsionando mudanças impactantes:

      ?Integração da Rede
      ?Avaliação de Recursos
      ?Avaliação de Impacto Ambiental
      ?Engajamento da Comunidade
      ?Análise de Risco
      ?Monitoramento e Manutenção
      ?Análise de Uso do Solo
      ?Planejamento de Infraestrutura Energética
      ?Mitigação de Mudanças Climáticas
      ?Mapeamento de Demanda Energética

      Deixe-me poupar algum tempo da sua frustração, pois você pode estar cometendo alguns erros comuns:

      ? Pular direto para a codificação sem um roteiro
      ? Seguir tutoriais que só fazem sentido se você já tiver conhecimento dos termos do WebGIS
      ? Tentar construir ferramentas sem entender o fluxo de dados no WebGIS
      ? Perder tempo “ajustando” ferramentas sem ter a mínima ideia de onde o código deveria ficar

      Parece familiar?

      Vou te contar alguns “segredos” para o desenvolvimento do seu WebGIS:

      ? Entenda o fluxo de dados e os termos essenciais
      ? Saiba exatamente quais elementos de programação são essenciais
      ? Domine o uso das bibliotecas WebGIS para obter exatamente o que precisava

    • sur Eclairez vos terrains avec Giro3D

      Publié: 28 November 2024, 6:47am CET par Sébastien Guimmara
      Pièce jointe: [télécharger]

      Cet article concerne des fonctionnalités en cours de développement et sujettes à évolution.

      L’éclairage dans Giro3D

      L’éclairage est un élément déterminant dans une scène 3D, et permet d’améliorer la lisibilité des volumes et du relief, notamment du terrain.

      Giro3D dispose de deux modes d’éclairage pour les terrains: simplifié et réaliste.

      L’éclairage simplifié (hillshading)

      ? Ce mode d’éclairage n’est compatible qu’avec l’entité Map dans un système de coordonnées projeté.

      Il s’exprime par un couple de valeurs (azimut, zénith) décrivant la position du soleil telle que perçue depuis le centre de la scène. C’est un mécanisme très similaire à celui proposé par QGIS par exemple.

      L’avantage de ce système est qu’il est très simple d’emploi, et familier des utilisateurs d’outils cartographiques.

      Son inconvénient majeur, en revanche, est qu’il ne fonctionne pas avec le mode globe, puisque l’axe des rayons du soleil n’est pas le même en tout point du globe (alors qu’il l’est en tout point d’une carte plane).

      Son autre inconvénient est l’absence de support de multiples sources lumineuses ainsi que les ombres portées.

      Une couche d'élévation sans éclairage actif

      Une couche d’élévation sans éclairage actif

      La même couche éclairé par l'éclairage simplifié

      La même couche éclairé par l’éclairage simplifié

      L’éclairage réaliste

      ? Ce mode d’éclairage n’était jusqu’ici pas supporté par l’entité Map.

      Le mode d’éclairage réaliste utilise les mécanismes du moteur three.js comme l’éclairage physiquement réaliste et les ombres portées pour produire une scène plus réaliste.

      Ce système permet d’utiliser un nombre arbitraire de sources lumineuses représentées par des objets 3D:

      La même couche d'élévation éclairée par une lumière directionnelle, une lumière d'ambiance et des ombres portées

      La même couche d’élévation éclairée par une lumière directionnelle, une lumière d’ambiance et des ombres portées

      Les ombres portées

      Le système d’éclairage réaliste permet également de visualiser des ombres portées ouvrant la voie à de nombreux cas d’usage, comme par exemple:

      • visualisation de l’ensoleillement d’une vallée à une heure donnée,
      • visualisation des ombres portées par des bâtiments sur une rue
      Les ombres portées par le Grand Canyon se combinent à celle de la sphère

      Les ombres portées par le Grand Canyon se combinent à celle de la sphère

      Conclusion

      Le support complet de l’éclairage three.js pour l’entité Map s’inscrit dans la philosophie de Giro3D de s’intégrer de façon aussi transparente que possible à l’écosystème three.js.

      Les ombres portées représentent une addition intéressante pour améliorer la qualité visuelle des scènes et aider à la prise de décision lors des analyses d’ensoleillement.

      Vous retrouverez toutes les fonctionnalités de Giro3D sur le site web et sur la page d’exemples interactifs.

      Si vous souhaitez en savoir plus, intégrer Giro3D dans votre système d’information, utiliser ces fonctionnalités pour de nouveaux usages, n’hésitez pas à contacter notre équipe à infos+3d@oslandia.com ! Nous serons ravis d’échanger avec vous.

      Oslandia sera présent à OSXP les 4 et 5 décembre 2024 à Paris. Le salon OpenSource eXperience est la grande rencontre annuelle des acteurs de l’open source.

      Retrouvez Vincent et Bertrand sur le stand de notre partenaire et client Orange E14 pour échanger sur vos projets ! Nous pourrons également vous présenter nos dernières réalisations.

      Le Groupe Orange a d’abord été utilisateur de produits open source, puis contributeur et éditeur. L’opensource est désormais une direction stratégique du groupe, avec un réel engagement pour être un acteur moteur de l’écosystème. En tant que premier partenaire OpenSource d’Orange, Oslandia est fière d’accompagner ce mouvement !

    • sur [Story] Oslandia x QWC : épisode 6 / 8

      Publié: 26 November 2024, 7:18am CET par Benoît Blanc

      Nous avons détaillé précédemment notre activité de développement fonctionnel autour de QWC, et les ajouts que nous avons pu réaliser. Aujourd’hui, nous évoquons la maintenance !

      En plus de ces fonctionnalités, nous sommes confrontés lors des développements ou via des remontées de clients à des anomalies dans QWC. Oslandia réalise donc un travail continu de maintenance corrective sur la solution, pour améliorer sa qualité et sa robustesse.

      Nous avons résolu ces dernières années plusieurs problèmes dont:

      • l’amélioration du plugin de Ligne de temps (qui permet d’utiliser les données temporelles) où beaucoup de petits problèmes cumulés faisaient crasher l’application
      • certains bugs dans la fonctionnalité de recherche
      • Divers soucis sur les services QWC ont été corrigés
        • problèmes de génération de la configuration
        • problèmes de permissions pour l’édition de données

      La maintenance des produits OpenSource est un sujet critique, et souvent plus difficile à financer que les développements fonctionnels. Concernant QWC, la maintenance est possible grâce à :

      • la collaboration et la mutualisation de la maintenance entre les différents contributeurs ( e.g. SourcePole )
      • l’auto-investissement OpenSource d’Oslandia, dont une partie est dédiée à la maintenance des composants clef de nos infrastructure SIG
      • les contrats de maintenance QWC attribués à Oslandia

      Si vous souhaitez garantir la pérennité de vos applicatifs QGIS web, le meilleur moyen est d’opter pour un contrat de maintenance. Vous aurez ainsi une assurance contre toute mauvaise surprise. Contactez-nous ( infos+qgis@oslandia.com ) !

    • sur Free and Open Source GIS Ramblings: GeoParquet in QGIS – smaller & faster files for the win!

      Publié: 23 November 2024, 10:23pm CET

      tldr; Tired of working with large CSV files? Give GeoParquet a try!

      “Parquet is a powerful column-oriented data format, built from the ground up to as a modern alternative to CSV files.” [https:]]

      (Geo)Parquet is both smaller and faster than CSV. Additionally, (Geo)Parquet columns are typed. Text, numeric values, dates, geometries retain their data types. GeoParquet also stores CRS information and support in GIS solutions is growing.

      I’ll be giving a quick overview using AIS data in GeoPandas 1.0.1 (with pyarrow) and QGIS 3.38 (with GDAL 3.9.2).

      File size

      The example AIS dataset for this demo contains ~10 million rows with 22 columns. I’ve converted the original zipped CSV into GeoPackage and GeoParquet using GeoPandas to illustrate the huge difference in file size: ~470 MB for GeoParquet and zipped CSV, 1.6 GB for CSV, and a whopping 2.6 GB for GeoPackage:

      Reading performance

      Pandas and GeoPandas both support selective reading of files, i.e. we can specify the specific columns to be loaded. This does speed up reading, even from CSV files:

      Whole fileSelected columns
      CSV27.9 s13.1 s
      Geopackage2min 12s ?20.2 s
      GeoParquet7.2 s4.1 s

      Indeed, reading the whole GeoPackage is getting quite painful.

      Here’s the code I used for timing the read times:

      As you can see, these times include the creation of the GeoPandas.GeoDataFrame.

      If we don’t need a GeoDataFrame, we can read the files even faster:

      Non-spatial DataFrames

      GeoParquet files can be read by non-GIS tools, such as Pandas. This makes it easier to collaborate with people who may not be familiar with geospatial data stacks.

      And reading plain DataFrames is much faster than creating GeoDataFrames:

      But back to GIS …

      GeoParquet in QGIS

      In QGIS, GeoParquet files can be loaded like any other vector layer, thanks to GDAL:

      Loading the GeoParquet and GeoPackage files is pretty quick, especially if we zoom into a small region of interest (even though, unfortunately, it doesn’t seem possible to restrict the columns to further speed up loading). Loading the CSV, however, is pretty painful due to the lack of spatial indexing, which becomes apparent very quickly in the direct comparison:

      (You can see how slowly the red CSV points are rendering. I didn’t have the patience to include the whole process in the GIF.)

      As far as I can tell, my QGIS 3.38 ‘Grenoble’ does not support writing to or editing of GeoParquet files. So I’m limited to reading GeoParquet for now.

      However, seeing how much smaller GeoParquets are compared to GeoPackages (and also faster to write), I hope that we will soon get the option to export to GeoParquet.

      For now, I’ll start by converting my large CSV files to GeoParquet using GeoPandas.

    • sur Ajout du support de géométries 3D complexes dans QGIS 3.40

      Publié: 19 November 2024, 7:10am CET par Jean Felder

      [Un PolyhedralSurface de la forme d’un lapin dans le canvas 2D de QGIS]

      Initialement conçu pour la cartographie 2D, QGIS a vu apparaitre des capacités 3D ces dernières années. Suite aux efforts continus de développement portés par Oslandia depuis 3 ans sur cette composante de l’application, QGIS supporte désormais dans sa version 3.40 l’affichage et la manipulation de géométries 3D complètes, comme les surfaces polyhédrales et les réseaux triangulés irréguliers (TIN). Cela permet de visualiser des formes en 3D bien plus réalistes et complexes que de simples polygones.

      Pour mieux comprendre, voici une définition simple de ces géométries :

      • Une surface polyhédrale est une surface 3D composée de multiples facettes planes (des polygones ou des triangles) qui sont assemblées pour créer une forme en volume, avec un rendu réaliste de courbes et de reliefs.
      • Un réseau triangulé irrégulier (TIN) est une surface polyhédrale dont le maillage est constitué exclusivement de triangles de taille et d’angle variables.

      Ce nouveau support offre désormais la possibilité d’effectuer des traitements 3D (comme découper, fusionner, déplacer, etc.) via le plugin QSFCGAL. Ces avancées élargissent les perspectives pour les projets nécessitant une analyse 3D.

      Ces développements ont été rendus possible grâce au financement du CEA ainsi qu’à nos travaux de R&D financés par l’Union européenne – Next Generation EU dans le cadre du plan France Relance et du projet Cloud Platform for Smart Cities.

      Ces évolutions permettent ainsi de répondre aux besoins concrets de nos clients, par exemple en représentant des couches géologiques et en permettant de réaliser des coupes afin de connaitre la nature du sous-sol.

      I want a "start over" tool for type annotating a Python library. I started with Flask as untyped code, then added annotations until mypy stopped complaining. But this didn't mean the annotations were _correct_. Over time I've fixed various reported issues. I feel like if I could start from scratch again, I'd probably get closer to correct with the experience I've gained. But removing all existing annotations and ignores is too time consuming on its own. #python

    • sur Sean Gillies: Let's fucking go

      Publié: 13 November 2024, 3:16am CET

      I saw a physical therapist yesterday. I had a virtual visit with my physician today. I had a 2 mile hike in the sun around a local reservoir. Now I'm listening to the Glenn Branca Orchestra on The Frow Show and my take on my health is: let's go!

      The expert consensus is that I did not injure my spine, but that muscles in the left side of my hip have clamped down on a nerve. I'm going to proceed as if that is true, foam rolling, walking, and running through the pain, and not worrying about my spine cracking in pieces. I do have a little bit of numbness in my upper left leg and so I will not directly dive into long technical downhill runs. I expect that I'll resolve that soon.

      Publié: 12 November 2024, 2:46pm CET

      I've taken a momentary break from our (admittedly) glacial pace of MapGuide development to put out another release of mapguide-rest 

      This release includes the following changes:

      • Fix missing reverse routing on selection overview
      • Fix bad feature query preparation when querying against watermarked layers
      • Relax strict-typing on MgReaderToGeoJsonWriter::FeatureToGeoJson() so that it can work with MgPaginatedFeatureReader allowing pagination to work again
      • Added missing properties parameter to swagger defn for session-based feature selection route
      Download
      We now return to regularly-scheduled programming of trying to get MapGuide Open Source 4.0 to the finish line.
      As for mapguide-rest, I envision at least once more major RC *after* the final release of MapGuide Open Source 4.0 before finally wrapping things up on development work and pulling the trigger on the mapguide-rest 1.0 final release. Enough of this RC-after-RC business!

    • sur Nick Bearman: FOSS4G:UK South West 2024 - Bristol

      Publié: 12 November 2024, 1:00am CET

      It was great to attend FOSS4G:UK South West 2024 in Bristol on 12th Nov, at OSGeo:UK’s now regular Bristol Venue, The Engine Shed. The event was a sell out and we had 62 people in the Engine Shed’s main room.

      This was the first time in a while that I have been to a FOSS4G:UK as an attendee rather than as an organiser - and it made a nice difference! We had 14 great presentations, covering a whole range of topics including digitalization of railways, reproducible science, real time vessel monitoring, landscape heritage, open source funding, cloud native web apps and a whole variety of useful open source tools.

      Unfortunately I missed the first presentation - thanks Great Western Railways! - but one common theme that cropped up a lot was how social media as a tool for open source projects has changed dramatically. James Milner said that social media used to be a great way to promote his program, Terra Draw, but know he gets no where near the same impact from using social media. It’s now a bit of a big unknown, and I particularly liked how he summarised this:

      Interestingly, I sent out a number of social media posts to Twitter (X), Mastodon and LinkedIn, and LinkedIn got the most response, so make of that what you will! Although I think it’s fair to say LinkedIn is not universally loved, as it was memorably described as “Grindr for Business” by Andrew Bailey!

      The presenters have also mastered the use of memes, with Matt Travis hitting home with some of the perils of waiting for large data sets to load:

      and of course also

      It was also fantastic to get FAIR Open Science and FAIR workflows mentioned in the presentation by Richard Conway & Garin Smith from Telespazio, who are in the process of developing an exploration platform that allows researchers both to share their data, code and their methods in a reproducible form.

      I also had the opportunity to speak about GoFundGeo and talk about how OSGeo:UK is funding a range of open source geospatial projects that will have an impact in the UK. Join the OSGeo:UK mailing list or check the website to find out more.

      Finally, as ever, it was great to meet new people and network again with old friends at these events. I know of at least one contract opportunity, as well a number of potential ones and also I think some new volunteers for OSGeo:UK!

      Thanks very much to all the organisers - Pascal Coulon, Alastair Graham, Sam Franklin, Dan Ormsby, Illya Sparkes-Santos, Ant Scott, as well as everyone who came along and took part.

      Exploring CQL and ECQL Filtering in GeoServer

      In this session, we want to talk about the Using CQL/ECQL Filters in GeoServer in detail. If you want to access the complete tutorial, click on the link.

      Introduction

      Contextual Query Language (CQL) is a text-based query for search/retrieval adopted by the OGC for the Catalogue Web Services specification. Unlike the XML-based Filter Encoding language, CQL is more readable and easier for manual authoring. However, it has limitations, such as not being able to encode ID filters and requiring the attribute to be on the left side of comparison operators.

      To overcome these limitations, GeoServer offers an extended version called ECQL, which closely resembles SQL and provides greater flexibility. ECQL allows users to define filters for querying data in GeoServer using attribute comparisons, logical operators, and spatial predicates. It is compatible with GeoServer’s REST API and can be used for WMS and WFS requests to retrieve filtered data.

      Note. This video was recorded on GeoServer 2.22.4, which is not the most up-to-date version. Currently, versions 2.25.x and 2.26.x are supported. To ensure you have the latest release, please visit this link and avoid using older versions of GeoServer.

      Note. Future version of GeoServer will include support for CQL2 which provides both a text and a JSON representation.

      Comparison operators

      To compare attribute values or other numeric and text values in your CQL / ECQL (Extended Common Query Language) expressions, you can utilize comparison operators.

      In the Layer Preview section, first click on the OpenLayers option for the topp:states layer. Next, locate and click on the Toggle options toolbar in the top left corner to access the advanced options.

      In the CQL filter box within this toolbar, enter the filter expression STATE_NAME = 'Texas', and then press the Apply button. This filter will retrieve and display the data for the state of Texas.

      By reviewing the following examples using the Toggle options toolbar from the LayerPreview page, you will learn how to effectively understand and apply comparison operators using CQL/ECQL expressions:

      • ‘PropertyIsGreaterThanOrEqualTo’ filter

      This filter shows the states that have more than or equal to 5 million inhabitants.

      PERSONS >= 5000000
      • ‘PropertyIsLike’ filter

      This filter shows the states whose names, contain the letters ‘ing’ like Washington and Wyoming.

      STATE_NAME like '%ing%'
      • ‘PropertyIsBetween’ filter

      This filter shows the states with a population of 5 million to 10 million.

      PERSONS between 5000000 and 10000000
      Spatial operators

      These operators enable you to perform spatial queries and filter data, based on various relationships between geometries. Here are the explanations for some commonly used spatial operators:

      • ‘Intersect’ filter

      This filter allows you to query spatial data in GeoServer based on geometric intersection relationships. This filter returns all features that have any spatial intersection or overlap.

      The syntax for the Intersect filter in CQL is as follows:

      Intersects(the_geom,Point(-90 40))
      • ‘Within’ filter

      The Within filter checks if a spatial object is completely within another spatial object. This filter retrieves all features that are located within the boundaries of a specified geometric shape, using spatial relationships.

      Within(the_geom,Polygon((-100 30,-100 45,-80 45,-80 30,-100 30)))
      • ‘Contains’ filter

      This filter is the inverse of the “Within” filter. It checks if a spatial object completely contains another spatial object and helps you retrieve features that fully enclose the specified geometry.

      CONTAINS(the_geom,LINESTRING(-73.9 43.5,-77.76 42.56))
      Bounding Box operators

      The Bounding Box operator is used to filter data based on a specified bounding box. The “bbox” filter in CQL allows you to query spatial data in GeoServer based on a bounding box or a rectangular area.

      CQL filters can also be utilized with the GET method. To use the bbox filter using the GET method, enter the following code in the URL address bar of your browser:

      http://localhost:8080/geoserver/topp/wms?service=WMS&version=1.1.0&request=GetMap&layers=topp:states&bbox=-124.73142200000001,24.955967,-66.969849,49.371735&width=768&height=330&srs=EPSG:4326&format=application/openlayers&CQL_FILTER=BBOX(the_geom,-110,41,-95,45)

      This filter enables you to retrieve all features that intersect, or are contained within the specified bounding box.

      In this session, we took a brief journey through the “CQL filtering in GeoServer”. If you want to access the complete tutorial, click on the link.

    • sur Sean Gillies: A new CLI for GDAL

      Publié: 9 November 2024, 5:54pm CET

      Even Rouault has proposed a new, modern, and more coherent command line interface (CLI) for the GDAL/OGR project. I think it's a good idea and a good time to do it. I've wanted a better one for about 15 years. Even credits Rasterio for inspiration, and that's gratifying to see. I started writing Rasterio 10 years ago in part because I wanted a better CLI for GDAL.

      What I wanted in a GDAL CLI were the following features:

      • A root command and a few subcommands, one namespace for everything.

      • Uniform arguments and options with predictable ordering and naming.

      • Good documentation of arguments and options.

      • More subcommands with fewer options each. Making gdal_translate into 3-4 commands, for example.

      • Input and output that favor stdin/stdout and JSON.

      • Ease of installation. For example, with pip instead of an OS package manager.

      I estimated in 2013-2014 that it was not feasible for me to achieve those goals within the GDAL project itself. GDAL and its community had no funding for this kind of work at the time. I found the GDAL project's tests somewhat inscrutable and frustrating. A hefty legacy of documentation and folk wisdom about the old ways would have to be updated. Mostly by me, certainly. And the GDAL user community largely did not care. Free software that was fast and effective (and, most of all, free!) was already more than most people had dreamed of. A GIS analyst had so many business and organizational problems to deal with already that the rough edges of gdalinfo and gdal_translate didn't even crack her top 20. Software polish wasn't a big concern in the second decade of FOSS4G. I think it's still a hard thing to sell. Individual consumers will pay money for slick, well-designed software that makes them feel good. Organizations value polish less. And neither GDAL nor Rasterio sell anything to individual consumers.

      Overhauling gdal_translate, ogr2ogr, and friends within the GDAL project looked like a non-starter to me. Pushing a herd of boulders up a hill, by myself, for free, for a community that was largely content with working around and stepping over these boulders. I think I made the right choice for myself. I got to start from scratch, move fast, and use a modern CLI framework. I made a command line interface for Rasterio that, while not perfect, met most of my goals. And I didn't go broke or burn out while doing it.

      Today, thanks to years of fundraising work by Howard Butler, Paul Ramsey, Kristian Evers, and Even, the GDAL project does have funding to overhaul its command line interface as an aspect of overall project health and maintenance. Multiple developers can be paid to work on it. They won't have to donate their time to it as I would have. Rasterio's command line interface can't be adopted by GDAL, or be forked to become GDAL's because it doesn't have all the features of existing GDAL programs (or even of gdal_translate and ogr2ogr for that matter), and my decision to have more subcommands with fewer options is kind of against the grain of GDAL. But the new GDAL CLI can adopt the demonstrably useful features and design of Rasterio's. JSON output, for example, is something that GDAL has already picked up from Rasterio.

      Rasterio will certainly fade a little if the new GDAL CLI is designed and executed well. But that's in the nature of software and software communities. Rasterio has always depended on GDAL and benefited from being built on a technically solid and well loved foundation. And I didn't invent CLI subcommands and JSON output, not at all. It's not unfair. If you succeed in open source, if you move the needle, you will be emulated. In this case, I think we can call it progress. I'm content.

      In the long run, I stand to get half of what I originally wanted from a GDAL CLI, the first three of the six features I listed above. And there's probably still room for a suite of Unix style programs with different opinions and design decisions, especially if it and GDAL agree on basic concepts, arguments, options, and flags.

      Nous avons récemment détaillé les ajouts fonctionnels génériques qui ont été intégrés directement dans le cœur de QWC.

      Mais parfois, certains développements ne sont pas publiés !

      En effet, en plus de ces ajouts aux dépôts de QWC, nous avons également développé certaines fonctionnalités spécifiques pour nos clients, qui n’ont pas forcément leur place dans ces dépôts, étant donné qu’elles ne peuvent être applicables à n’importe quel utilisateur de QWC.

      De façon générale, lorsque nous analysons une demande client, nous distinguons parmi les fonctionnalités à développer, celles qui sont génériques et celles qui sont spécifiques. Oslandia veille à contribuer “upstream” toutes les fonctionnalités génériques, afin qu’elles participent à l’enrichissement du bien commun, et qu’elles favorisent la dynamique opensource de mutualisation des projets.

      À l’inverse, les fonctionnalités spécifiques sont gardées sur des dépôts privés pour le client, même si elles sont opensource : il n’y a pas d’intérêt à les publier, et elles ont souvent une adhérence à un SI particulier, ou une structure de données particulière.

      C’est ainsi que nous avons développé un service de parcours de réseau d’eau potable pour détecter des fuites d’eau ou des incidents, un service de recherche utilisant PostgreSQL Full Text Search, ou une recherche sur des données cadastrales. Ces fonctionnalités sont intégrées dans les applications pour nos clients, et bénéficient des apports précédemment réalisés dans le cœur de QWC.

    • sur Fernando Quadro: Etapas básicas para criar seu WebGIS

      Publié: 30 October 2024, 1:00pm CET

      A melhor prática para criar um sistema WebGIS é armazenar todos os seus dados espaciais em um servidor PostgreSQL habilitado para PostGIS. Garanta que a indexação espacial seja aplicada para recuperação de dados mais rápida.

      Você pode facilmente construir uma interface intuitiva e amigável usando HTML básico, CSS, Bootstrap e JavaScript.

      Use Leaflet ou OpenLayers como sua biblioteca de mapeamento padrão!

      Para filtrar dados ou executar consultas, siga estas etapas:
      ? Colete a entrada do usuário e envie-a para seu script de backend por meio de uma solicitação AJAX.
      ? Valide a entrada no backend e busque os dados necessários do banco de dados PostgreSQL usando consultas SQL.
      ? Prepare os dados no backend e envie-os de volta para o cliente (interface do usuário).
      ? O cliente receberá os dados por meio da mesma chamada AJAX e os formatará em camadas Leaflet. AJAX é assíncrono.
      ? Estilize suas camadas de forma eficaz usando funções JavaScript.
      ? Exiba as camadas no mapa.
      ? Ajuste automaticamente a visualização do mapa para se ajustar à extensão do recurso pesquisado.
      ? Adicione-os a um controle de camada para alternar a visibilidade entre ligado e desligado.
      ? Crie dicas de ferramentas ou pop-ups para exibir informações detalhadas.
      ? Se o usuário pesquisar por um único recurso, desenhe um círculo, linha ou polígono ao redor dele e amplie o recurso.

      Estas são as etapas básicas para exibir dados em um sistema WebGIS.

    • sur Fernando Quadro: Por que utilizar um WebGIS?

      Publié: 29 October 2024, 1:00pm CET

      Porque mais e mais empresas estão migrando para publicar seus produtos e serviços como WebGIS ou disponibilizando seus dados e funcionalidades pela web.

      Essa mudança faz parte da tendência mais ampla conhecida como “GIS moderno”.

      A mudança para o WebGIS oferece benefícios significativos.

      ? Aqui estão as principais vantagens do WebGIS:

      1. Alcance um público mais amplo: os aplicativos WebGIS podem ser acessados ??globalmente por qualquer pessoa com uma conexão de internet, simplesmente usando uma URL.

      2. Nenhuma instalação necessária: como o WebGIS é baseado em navegador e os navegadores geralmente são pré-instalados na maioria dos dispositivos, os usuários podem acessar os aplicativos instantaneamente sem a necessidade de instalação complexa de software.

      3. Compatibilidade entre plataformas: o WebGIS funciona perfeitamente em todos os sistemas operacionais (Windows, Mac, Linux, etc.) usando navegadores da web padrão.

      4. Custos mais baixos: as empresas podem reduzir despesas usando infraestrutura de nuvem e evitando ou reduzindo a necessidade de licenças de software caras.

      5. Colaboração em tempo real: vários usuários podem interagir com os mesmos dados simultaneamente, permitindo colaboração em tempo real de diferentes locais.

      6. Atualizações instantâneas: quaisquer atualizações ou alterações nos aplicativos podem ser disponibilizadas imediatamente para todos os usuários, sem exigir atualizações manuais ou reinstalações — basta atualizar o navegador.

      7. Mais fácil para usuários não técnicos/não GIS: os aplicativos WebGIS geralmente oferecem interfaces intuitivas, tornando-os acessíveis até mesmo para especialistas não GIS que precisam executar tarefas específicas.

      8. Escalabilidade: as soluções WebGIS podem ser dimensionadas facilmente para lidar com cargas de dados crescentes e demandas do usuário, fornecendo flexibilidade para empresas em crescimento.

      O WebGIS ajuda as empresas a fornecer serviços e aplicativos com tecnologia GIS de forma mais eficaz, tornando-os acessíveis, eficientes e fáceis de usar para seus clientes e empresas.

    • sur Fernando Quadro: Interação entre Temperatura e Fluxos oceânicos com IA e GIS

      Publié: 28 October 2024, 1:00pm CET

      A combinação de Inteligência Artificial (IA) e Sistemas de Informação Geográfica (GIS) pode transformar nossa compreensão dos oceanos e suas dinâmicas. Aqui estão algumas formas de como essa interação entre temperatura e fluxos oceânicos pode ser otimizada com essas tecnologias:

      ? Monitoramento em Tempo Real: Usando sensores e dados via satélite, o GIS pode mapear padrões de temperatura oceânica e fluxos em tempo real, enquanto a IA analisa grandes volumes de dados para prever mudanças futuras.

      ? Previsões Climáticas Precisas: A IA é capaz de identificar padrões históricos de temperatura e fluxo oceânico para criar modelos preditivos, ajudando a antecipar fenômenos como o El Niño ou a La Niña, além de mudanças em correntes oceânicas.

      ? Gestão de Riscos e Desastres: Previsões aprimoradas permitem uma melhor gestão de riscos para eventos climáticos extremos, como tempestades ou inundações, dando tempo para se preparar e minimizar impactos.

      ? Otimização de Rotas Marítimas: Com o uso de GIS e IA, é possível otimizar rotas de transporte marítimo, aproveitando correntes oceânicas e temperaturas favoráveis, economizando combustível e reduzindo emissões.

      ? Conclusão: A combinação de IA e GIS na análise de temperatura e fluxos oceânicos oferece uma visão mais profunda e preditiva do comportamento dos oceanos, essencial para a gestão ambiental, segurança e planejamento climático.
