      This week's OSM Weekly links to a new interactive chatbot which allows you to interact with OpenStreetMap data. Rohit Gautam's OSM GPT allows you to use natural language queries to search OpenStreetMap. For example the screenshot above shows the results of 'Get all bars' in New York. It also shows the results of a query to 'Get all McDonald's restaurants'.I don't know how OSM GPT works but I

    • sur Jackie Ng: Where's the new Maestro API nuget packages?

      Publié: 7 August 2023, 1:34am CEST

      There were a few things I left out of the previous announcement that I'll use this post to address.

      Firstly, the 6.0m12 release of MapGuide Maestro formally drops all Fusion editor support for integration with Google Maps tiles and services. We no longer support Google Maps integration in Fusion and the editor in previous releases gave the false impression that this is still possible. That is no longer the case with this release.

      Secondly, the more important thing (and the subject of this post) is that if you are using the Maestro API and consume this through nuget packages from nuget.org you may be wondering why there are no new versions?

      The answer to that one is simply: My nuget package publishing keys have expired and something in the nuget.org website or something with my nuget.org account is preventing me from regenerating these keys or to generate a fresh set. As a result, I currently cannot upload any new nuget packages to nuget.org

      But do not fret, because there is an alternative solution.

      As part of the MapGuide Maestro release on GitHub, the nuget .nupkg files are also included


      From here, you can set up a local directory-based nuget package source, drop the .nupkg files into it and the this version of the package is available to install in your Visual Studio solution.

      If/when I get a resolution on this publishing key matter, I will upload the .nupkg files for this release and make another announcement. Until then, this local package source is a suitable workaround.

    • sur Narcélio de Sá: A Importância das Conferências do State of the Map para o OpenStreetMap

      Publié: 6 August 2023, 7:46pm CEST

      Se você teve a sorte de participar de uma conferência do State of the Map (SotM), já sabe que elas oferecem alguns dos melhores conhecimentos, habilidades e treinamentos em SIG (Sistemas de Informações Geográficas) e geoespaciais disponíveis. Isso é além de ser um evento de networking fantástico, com muito tempo social divertido e envolvente. Se você é novo na comunidade do OpenStreetMap e ainda não participou de um SotM, ou faz parte de uma empresa pensando em patrocinar um SotM, juntamente com o envio de uma equipe para participar, este post é para você.

      Image credit: Parker Michels-Boyce Photography. Please tag @OpenStreetMapUS in social media posts when using these photos. O que é um State of the Map – SotM?

      Os membros da comunidade do OpenStreetMap (OSM) organizam encontros anuais do State of the Map como uma forma de construir comunidade, compartilhar ferramentas e pesquisas, e estabelecer contatos entre si com o objetivo comum de melhorar o mapa. Esses encontros têm diversos tamanhos e são organizados local, regional e globalmente, mas o objetivo é sempre o mesmo: se reunir para discutir pesquisas sobre a criação de mapas, ferramentas, iniciativas e outros tópicos da comunidade. Os SotMs locais e regionais são organizados por comunidades locais, e o SotM global é organizado pela Fundação OSM.

      As conferências do Estado do Mapa estabelecem pontes entre os mapeadores do OSM e ativistas comunitários, desenvolvedores de código aberto, pesquisadores de universidades e instituições acadêmicas, designers, cartógrafos, bem como profissionais de tecnologia de empresas privadas e instituições públicas.

      Quais Tipos de Tópicos são Discutidos?

      A variedade de tópicos é tão diversa quanto a comunidade. As apresentações variam desde “palestras relâmpago” de 5 minutos até apresentações de 15-20 minutos e workshops de 75 minutos. Eles abordam temas como desenvolvimento de plataformas e ferramentas, análise de dados, mapeamento humanitário e muitos outros. Os apresentadores estão afiliados a comunidades locais, Youthmappers, HOTOSM, maplibre, FOSS4G, academia, outras organizações sem fins lucrativos e empresas pequenas e grandes.

      A conferência global SotM de 2022 em Firenze, Itália, fornece um bom exemplo da variedade de informações e habilidades representadas em um SotM. Aqui estão apenas alguns títulos de sessões: “OSM Carto as Vector tiles; Innovating on Derivative OpenStreetMap Datasets”, Mapping a Small Town”,  “maplibre-rs: Cross-platform Map Rendering using Rust”, “Ten Years iD Editor—The Road Ahead”, “Women Leadership in Mapping Riverside Communities in the Amazon Forest Using OSM.”

      Esses exemplos mal arranham a superfície. Aqui está o programa completo e as gravações das apresentações. Há também uma exposição de pôsteres – sim, até as paredes do SotM de 2022 eram educacionais! E há um resumo dos procedimentos acadêmicos.

      Portanto, como você pode ver, um SotM oferece inspiração e conhecimento para qualquer pessoa interessada no futuro da tecnologia geoespacial, OpenStreetMap e software e dados livres e de código aberto.

    • sur Sean Gillies: Never Summer training weekend recap

      Publié: 5 August 2023, 4:15am CEST

      Thursday, July 27, I drove west on CO-14 up the long Poudre River canyon and over Cameron Pass to Gould, the base for the Never Summer 60K and 100K races, for three days of camping and running in the mountains. Friday I would run the 60K race, Saturday I would go out for a few hours in the morning, and Sunday I would run a few more hours before driving home. Back-to-back-to-back easy long runs at high elevation to help me get in shape for the Bear 100 in September.

      I had completely fair weather for the drive and for setting up my tent. I tossed a drop bag with spare shoes and socks in the truck bound for the Bockman aid station, caught up with other runners who I haven't seen in a while, cooked some quinoa for dinner, and tucked myself in.

      https://live.staticflickr.com/65535/53093597086_c49bd699cf_b.jpg

      Thunderstorms passed over Gould almost all night long. I slept fitfully, and struggled to get my act together before the 5:30 a.m. start. I tied my shoes in the last 30 seconds before race director Nick Clark let us go. Not being a morning person, getting to the start on time is always a challenge for me.

      After two miles of rolling along the margin of the valley floor, the course climbs steeply up Seven Utes Mountain. I stopped feeling groggy and started feeling the effort. I hiked the whole thing, comfortable at the back of the pack, and in a little over an hour, I was on top of the first alpine summit.

      Runners heading down from the summit of Seven Utes Mountain, mile 6

      My plan for the day was to go at an average pace of 20 minutes per mile. At the Bear 100, this would equate to a 33 hour finish, comfortably within the 36 hour cut off. I got to the Michigan Ditch aid station (11 miles) ahead of schedule and reached the Diamond Peak aid station (19 miles) 45 minutes ahead of schedule. The segment between them climbs 1000 feet, then becomes a highly runnable downhill. I ate solid food at the aid station, filled some pockets with cookies, and took 3 soft bottles of VFuel (race sponsor) solution to get me through the Diamond Peak climb and the ridge connection to Montgomery Pass.

      Sweltering conditions made the first part of the Diamond Peak climb tough. A steady breeze above treeline helped make the slow, steep slog up the ridge more comfortable. The last unforgettable mile of the climb has a vertical gain of 1370 feet.

      The ridge between North Diamond Peak and Montgomery Pass, mile 21

      I took it easy on top, taking lots of pictures with my phone, and texting them to my family. News from the course always makes my mom happy. I reached the Montgomery Pass aid station a little less than three hours after leaving the Diamond Peak aid station.

      I've been recovering from a back injury, perhaps from my crash at Kettle Moraine, and by the time I reached Montgomery Pass it had seized up. I wasn't able to do any consistent downhill running after this point. Still, seven hours of pain free running and hiking felt like major progress. I hope I'll be close to 100 percent by the Bear. I hiked down to Bockman aid station, did not change shoes and socks, grabbed more drinks and cookies, and hiked and jogged intermittently to the finish. I was just seven minutes over my goal.

      Fort Collins runners Clint Anders and Jenna Bensko won the men's and women's divisions. Full results are here on OpenSplitTime.

      Saturday morning I woke early to the sounds of the 100K race starting, dozed for another two hours, then drove 45 minutes to the Bockman aid station. It was dormant at 9. It is the 100K race's 50 mile mark and the first runner wouldn't be arriving before 2 p.m. From Bockman, I hiked the course in reverse to the Ruby Jewel aid station, then went forward on the course to the pass overlooking Kelly Lake, roughly mile 35. The lead runner and eventual winner, Zachary Russell, caught up to me just before the top. I stuck around to see the next ten runners come over, then headed back to Ruby Jewel. Saturday was warm, and the closer I got to Ruby Jewel, the more suffering I saw on faces. I heard later that 50 runners dropped out there at mile 31.

      Pass above Kelly Lake, mile 35

      I returned to Bockman, hung out there chatting with the aid station crew for a bit, then went for a swim in North Michigan Reservoir, a place where I've camped with my family, and which is full of water again after being drained for maintenance of the dam in 2021. After cooling and washing off, I returned to my camp at the race finish to change and get ready to work at the kitchen. From 6 p.m. until midnight I washed dishes and served food to runners. The kitchen group was a lot of fun and was lead by an actual chef who does the same duty at Hardrock 100 and a few other serious races. People are super grateful for a hot meal after a long day on the trail or at an aid station, and there isn't anywhere to eat in Gould. I would do this again.

      100K finish line

      I slept very little Saturday night. Runners trickled in until 6 a.m., and Brad Bishop (volunteer coordinator and finish line announcer among many roles) read every name and number over the PA system. On the bright side, I did hear names I knew, and was glad for them. My friend Ivan became the 100K race's first 70 year old finisher at 3:50 a.m.

      After breaking camp and packing my car, I said good-bye to people, and drove homewards, stopping at the American Lakes trailhead for one more trip to that beautiful alpine basin. This time I went all the way to Thunder Pass for the view into Rocky Mountain National Park.

      https://live.staticflickr.com/65535/53093994330_7f4a58b3e6_b.jpg

      American Lakes basin from Thunder Pass

      Over the weekend, I spent 20 hours on trails, covered 100 kilometers distance, and climbed over 4,000 meters. A successful mountain training camp, for sure. I got signs that my back is healing, did some volunteering, hung out with my favorite runners, and met some fun folks for the first time. I don't know if I'll run this next year, but I'll be back to be a part of it.

      My position evaporated on Monday, one of many layoffs at my job. This is a first for me. If you've got advice, I'm all ears. If you're a former coworker and looking for help finding a new job, hit me up. I'm good at reviewing resumes and enjoy telling hiring managers good things about good people.

      I'm fortunate to be in a good position right now. My family is healthy, we are insured through Ruth's position at CSU, and have some savings. This is not the case for everyone who gets laid off, I know.

      Am I going to let this derail my attempt to finish a 100 miler in September? No way. Looking for work will take time, and I'm picking up more family duties, but it looks like I'll also have more free time to spend on the trail this summer.

      Publié: 1 August 2023, 10:41pm CEST

      Next stop on the tour: A new release of MapGuide Maestro

      This release includes the following notable changes.

      Improved MapGuide Open Source 4.0 authoring support

      This release improves the MapGuide Open Source 4.0 authoring experience with support for the new label justification setting for basic stylization labels.


      This setting is part of the new v4.0.0 Layer Definition XML schema, whose .xsd file is now also included with this release (so XML validation against this schema will work)

      Fusion editor enhancements for mapguide-react-layout features

      This release includes several enhancements to the Fusion Flexible Layout editor to support various features that can be taken advantage of when loaded into a mapguide-react-layout viewer. These new enhancements are accessible from the layout settings panel and require the latest release of mapguide-react-layout to leverage these new features.


      The Manage Custom Projections button opens up a new dialog that lets you manage and pre-register custom proj4 definitions for your application. By pre-registering these definitions in the Flexible Layout document itself, you can avoid needing to perform a epsg.io lookup for any projections found in the viewer init process that is not EPSG:4326 or EPSG:3857

      The Manage Settings button opens up a different dialog that lets you managed the app settings in the Flexible Layout document. These are arbitrary key/value pairs that your mapguide-react-layout viewer will be initialized with and your viewer code can read such settings at runtime to control and drive whatever custom functionality you may have.

      Other Changes

      • Improved layer editor UI responsiveness when layer points to a feature source with a really large schema
      • Increased schema walk/describe timeout to handle really large schemas
      • Fix: Connection error dialog buttons are no longer cut off
      • Fix: Transactional package drag-and-drop loading works again
      • Fix: Broken rest addin due to missing RestSharp dependency
      • Fix: Fill/line pattern dropdowns in layer editor are working again
      • Fix: MgTileSeeder will now accept bounding boxes outside the [-90, -180, 90, 180] lat/long domain by clamping any outside coordinates to be within this domain.
      Now onto the next stop: Finally giving mapguide-rest some long deserved attention!

    • sur Developers invited to the 2023 OGC API – Processes Virtual Code Sprint

      Publié: 31 July 2023, 3:00pm CEST par Simon Chester

      The Open Geospatial Consortium (OGC) invites developers to the 2023 OGC API – Processes Virtual Code Sprint to be held September 18-20, 2023, on Gitter. Registration for the code sprint is free and open to the public.

      Button for registration

      The Sprint will focus on refining the next version of the OGC API – Processes Standard and associated extensions. 

      The OGC API – Processes Standard supports the wrapping of computational tasks into executable processes that can be offered by a server through a Web API and be invoked by a client application. Typically, these processes combine raster, vector, coverage, and/or point cloud data with well-defined algorithms to produce new information. 

      Examples of computational processes that can be supported by implementations of OGC API – Processes include vector data analysis, imagery analysis, and various types of Artificial Intelligence (AI) enhanced analysis.

      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 new applications and candidate 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. The virtual code sprint will run from 9:00am to 5:30pm US Eastern Time each day.

      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.

      Registration for the 2023 OGC API – Processes Virtual Code Sprint is here. The Sprint will take place in the ogc-developer/Sprints Gitter room from 9:00am to 5:30pm (US Eastern) each day from September 18-20, 2023.

    • sur OGC adopts CityGML 3.0 Part 2: GML Encoding as an official OGC Standard

      Publié: 28 July 2023, 3:00pm CEST par Simon Chester

      The Open Geospatial Consortium (OGC) is excited to announce that the OGC Membership have approved the OGC City Geography Markup Language (CityGML) Part 2: GML Encoding Standard for adoption as an official OGC Standard.

      The CityGML 3.0 GML Encoding Standard presents the GML encoding of the concepts defined by the CityGML 3.0 Part 1: Conceptual Model (CM) Standard, which was approved as an OGC Standard in 2021. The GML encoding is compliant to OGC GML versions 3.2 and 3.3 (thus also ISO 19136). This encoding can be used to store and exchange 3D city models in the GML format as data sets or via web services.

      Since its first publication by OGC in 2008, CityGML has been an open standard used for the storage and exchange of virtual 3D city models. CityGML allows the integration of urban geodata for use across a variety of applications, including urban and landscape planning; Urban Digital Twins for Smart Cities; the Metaverse; Building Information Modeling (BIM); mobile telecommunication; disaster management; 3D cadastre; tourism; vehicle & pedestrian navigation; autonomous driving and driving assistance; facility management; and energy, traffic, and environmental simulations.

      CityGML defines a “City” in a broad fashion to comprise not just built structures, but also the land surface, vegetation, water bodies, city furniture, and more. Despite its name, CityGML is useful for large areas and small regions, not just cities, and can represent real-world terrain and 3D objects at different Levels Of Detail (LOD) simultaneously. CityGML enables the consistent representation of 3D urban objects across different Geographic Information Systems and users.

      CityGML 3.0 is an evolution of the previous versions 1.0 and 2.0 of CityGML that further enables the cost-effective sustainable maintenance of 3D city models. While previous versions standardized a GML exchange format, CityGML 3.0 standardizes the underlying information model and can thus be implemented in a variety of technologies beyond GML. As a result, governments and companies can increase the Return On Investment (ROI) of their 3D city models by being able to put the same models into play across different technology platforms and application fields. 

      This Part 2 of the Standard defines how the concepts developed in Part 1 are realized using XML and GML technologies. The CityGML 3.0 GML encoding represents a full mapping of the Conceptual Model. The encoding is derived fully automatically from the UML model following the UML-to-GML encoding rules as defined by ISO 19136.

      A collection of example data sets for the CityGML 3.0 GML Encoding is available from the OGC CityGML-3.0 Encodings Public GitHub Repository.

      OGC Members interested in staying up to date on the progress of this standard, or contributing to its future development, are encouraged to join the CityGML Standards Working Group (SWG) 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.

      As with any OGC Standard, the open CityGML Part 2: GML Encoding Standard is free to download and implement. Interested parties can learn more about, view, and download the Standard from OGC’s CityGML Standard Page.

      The post OGC adopts CityGML 3.0 Part 2: GML Encoding as an official OGC Standard appeared first on Open Geospatial Consortium.

    • sur Stefano Costa: Sono vegetariano da due anni

      Publié: 27 July 2023, 9:07pm CEST

      In questi giorni di fine luglio, due anni fa, ho deciso di smettere di mangiare carne e pesce e animali. Per un po’ di tempo, mi sono detto, ci provo. E sono passati due anni. Perché?

      Non è stata una decisione improvvisa e penso che siano anni che mi porto dietro l’idea di non nutrirmi più di altri animali, ma l’ho sempre considerata molto difficile da attuare, molto faticosa da spiegare. E invece è stato piuttosto semplice.

      Sono arrivato a questa decisione da due strade, il rispetto per gli animali e la convinzione che non esista un futuro per l’umanità carnivora.

      Il rispetto per gli animali mi porta a rimanere inquieto sul consumo di prodotti di origine animale, in particolare latticini e uova, poiché la loro produzione su larga scala richiede necessariamente quegli allevamenti intensivi disumani da cui provengono gli animali destinati alla macellazione. Ho quindi grande rispetto per chi pratica una alimentazione vegana e non capisco perché la prima domanda che mi viene rivolta quando dico di essere vegetariano è se io non sia mica vegano, nemmeno fosse una malattia infettiva. Ho ridotto il consumo di latticini, soprattutto lo yogurt che ho sostituito con prodotti alternativi che sono in prevalenza a base di soia. La coltivazione di soia non distrugge le foreste amazzoniche, per inciso.

      Le considerazioni planetarie sono le stesse che vengono ripetute da anni nell’ambito del discorso sulla crisi climatica globale. L’allevamento consuma una quantità di suolo enormemente superiore alla superficie richiesta per coltivare le piante in grado di fornire lo stesso apporto nutritivo. L’allevamento produce gas serra. Non cedo ai finti fondamentalismi eco-fascisti e credo che le popolazioni che praticano allevamento tradizionale debbano poter continuare a praticarlo. La stessa cosa non può essere detta per l’allevamento industriale tipico dei paesi occidentali. Queste sono convinzioni personali, che vorrei trovassero sponda in ambito politico.

      Sono un archeologo, conosco abbastanza bene la storia della cultura materiale dell’umanità e credo che i cambiamenti culturali che continuamente avvengono siano ben più significativi di qualunque “tradizione” a cui si vuole rimanere aggrappati. La lista delle pratiche oggi ritenute incivili e inconcepibili che “abbiamo sempre fatto” è lunghissima, quindi non c’è nessun ostacolo concettuale ad aggiungerci anche il consumo di carne.

      Ora sono un po’ più tranquillo quando mi siedo a tavola.

      About QGIS contributor meetings

      QGIS Contributors Meetings are volunteer-driven events where contributors to the QGIS project from around the world get together in a common space – usually a university campus. During these events, contributors to the QGIS project take the opportunity to plan their work, hold face-to-face discussions and present new improvements to the QGIS project that they have been working on. Everybody attending the event donates their time to the project for the days of the event. As a project that is built primarily through online collaboration, these meetings provide a crucial ingredient to the future development of the QGIS project. The event is planned largely as an ‘unconference’ with minimal structured programme planning. We do this to allow attendees the freedom to meet dynamically with those they encounter at the event. Those sessions that are planned are advertised on the event web page, and we try to enable remote participation through video conferencing software. Although our hosts are not funded and donate the working space to us, we show our appreciation by making one of our software release’s splash screens in honour of that host, which is a great way to gain exposure of your institution and country to the hundreds of thousands of users that make use of QGIS.

      About OSGeo

      The Open Source Geospatial Foundation (OSGeo) has a long tradition of organizing code sprints for developers of Free and Open Source GIS software.

      Since 2009, the Open Source Geospatial Foundation (OSGeo) has been organizing a yearly Code Sprint of the “C Tribe” OSGeo projects, which has evolved into a full OSGeo Community Sprint and all “Tribes” are included/welcome. Leading developers of projects like GDAL, PostGIS,
      MapServer, GeoServer, GRASS, QGIS, PDAL, pygeoapi and many more get together to discuss new ideas, hack, decide, tackle large geospatial problems and have fun.

      The OSGeo Community Sprint is open to all who wish to participate in one or more projects. There is always plenty to do – it’s not all about programming. Translation, documentation, feedback, discussions, testing – all this is also important for projects so everyone is cordially invited to attend the code sprint!

    • sur Volker Mische: FOSS4G 2023

      Publié: 22 July 2023, 9:50pm CEST

      Finally, after missing one virtual and one in person global FOSS4G I had again the chance to attend a global in-person FOSS4G conference. Thanks Protocol Labs for sending me. This year it was in Prizren, Kosovo. I’m a bit late with that post, but that’s due to doing some hiking in Albania right after the conference.

      The organization and venue

      Wow. It’s been my favourite venue of all FOSS4Gs I’ve been to so far. The exhibition hall was a great place to hang out, combined with the excellent idea of a 24h bar. I’m not sure if it was used at all times, but definitely for more than 20h a day. Outside, there was plenty of space and tables to hang out, and very close by another set of tables that formed the “work area”. Which was another great place to hang out, with enough power sockets and shade for the hot days.

      The main stage was an open air stage with enough seating for everyone. It was converted for the gala dinner to a stage with an excellent live band and the usual big round tables.

      For me, the best part was that even the accommodation was on-site. The barracks of the former military basis, which now serve as student dorms, were our home for a week. Pretty spartan, but at a conference I don’t really spend much time in my room, I mostly need just some place to sleep.

      Having everything, the talks, exhibition, social events and accommodations on-site makes it easy to maximize the time for socializing, which for me is the number one reason to attend a conference.

      Everything was well organized, and it was great to see so many volunteers around.

      The talks

      I haven’t really selected the talks I went to. I rather joined others where they were going, or listened to recommendations. Often, I just stayed in the rest of the slot to see what else is there. My favourite talks were:

      • Smart Maps for the UN and All - keeping web maps open: For me, it was the first time I saw someone speaking at a FOSS4G about using IPFS that wasn’t me. It’s great to see that it gains traction for the offline use case, where it just makes a lot of sense. UN Smart Maps is part of the UN OpenGIS initiative, it features a wide range of things, even an AI chatbot called TRIDENT that transforms the text into Overpass API calls. Try TRIDENT it out yourself, when you open the developer console, you can see the resulting Overpass API calls.
      • Offline web map server “UNVT Portable”: This talk got into more detail about using Raspberry Pis to have map data stored in IPFS for offline use. It’s very similar to what I envision, the only difference is that I’d also like to keep the storage in the browser. But I surely see a future, where those efforts are combined, to have a small easy server you can deploy, with in browser copies of subsets of the data to be able to work completely offline in the field. The original UNVT Portable repository doesn’t use IPFS, but Smart Maps Bazaar does, which seems to be its successor.
      • B6, Diagonal’s open source geospatial analysis engine: A presentation of the B6 tool for geospatial analysis for urban planning. It has a beautiful interface. I really like the idea of doing things directly on the map in a notebook-style way, where you perform certain steps after each other.
      • Elephant in the room: A talk about how many resources to computations take? Do we always need it? It’s very hard, often impossible, to find out how environmentally friendly some cloud services are. One of the conclusions was that cheaper providers likely use less power, hence are harming the environment less. I would like if there would be better ways (e.g. it misses things like economies of scale of large providers), but I agree that this might be the best metric we currently have. And I also hope there will be more economic pressure to save resources.
      • There was a closing keynote from Kyoung-Soo Eom, who was talking about his long journey in open source GIS, but also his history with Kosovo, where he was also on a mission in 1999. Quite inspiring.
      My talk

      My talk about Collaborative mapping without internet connectivity was about a browser based offline-first prototype that uses IPFS to enable replication to other peers. The project is called Colleemap and is dual-licensed under the MIT and Apache 2.0 license. Although I tried the demo bazillion times before my talk, it sadly didn’t work during my talk. Though, trying it later with various people, I was able to get 4 peers connected once. I even saw it working on a Windows machine. So it really works cross-platform.

      For the future I hope to work closer with the people from the UN OpenGIS initiative, it would be great to combine it with their Raspberry Pi based prototype.

      Things I’ve learnt

      The Sentinel-2 satellite imagery is available from multiple sources, directly from Copernicus Open Access Hub or through cloud providers like AWS, Azure of Google Cloud. From the cloud providers you only get the level-2 data. They might use the original level-2 data or do their own atmospheric correction based on the level-1 data. Or even re-encode the data. So it’s hard to tell which kind of data you actually get.

      As far as I know (please let me know if I’m wrong), there isn’t any mirror of the full level-1c data. You can only get it through the Copernicus Open Access Hub and there the older images are stored in the long term archive on tape, where it can take up to 24h for the data to be available for download (if it works).

      Ideally, there would be a mirror of the full level-1c data (where the ESA would provide checksums of their files) and a level-2 version, where the exact process is openly published, so that you can verify how it was created. The problem is the storage cost. The current level-2 data is about 25 PiB, which leads to storage costs of over $500k USD a month if you would store it on AWS S3 Standard at the current pricing (I used the $0.021 per GB).

      Final thoughts

      It was great to meet Gresa and Valmir from the local organizing committee before the FOSS4G in March at the OSGeo German language chapter conference FOSSGIS in Berlin. That made it easy for me to connect to the event right from the start. If there’s one thing future FOSS4Gs should adapt, it’s the cheap on-site (or close by) accommodation. I think that shared bathrooms is also much smoother to have, if you know that everyone in the accommodation is from the conference. We had something similar with the BaseCamp in Bonn during the FOSS4G 2016 and the international code spring in 2018 during the FOSSGIS conference, where the whole place was rented for the time of the events.

      Though, of course, I also missed some of my longtime FOSS4G friends I hadn’t seen in a long time. I hope you’re all doing well and will meet again soon.

      Publié: 19 July 2023, 12:50pm CEST

      Our journey needed to make a temporary detour, with another release of mapguide-react-layout.

      This release has the following notable changes

      Legend layer and group customization supportThis release provides a new viewer init option to allow layer and group elements of the Legend component to be augmented with additional HTML content. For example, we can use this to add a download link for specific layers (how to actually implement the download link is an exercise left to you the reader)


      See this comment for an example of how to customize the layer and group elements.Reduced excessive re-renderingIn the process of implementing the above feature, we discovered that some components (the Legend component in particular) did a lot of pointless re-rendering which contributes to sluggishness in viewer performance.
      For this release, great efforts were made to ensure that component re-rendering is the result of legitimate changes to component state and not from pointless re-rendering from bogus shallow state "changes"
      Removed IE-specific polyfills and workaroundsInternet Explorer ceased to be a supported browser by Microsoft for some time now. This release formally removes our various IE-specific workarounds and polyfills that were only there to support this ancient browser.
      Other changes
      • The urlPropsIgnore setting is now considered when the viewer updates the URL state
      • The viewer bundle patches OpenLayers to log a console warning and abort rendering when attempting to render a map overlay image with a width/height/scale/dpi of 0
      • Fixed an issue where no map images are rendered if the browser zoom is below 100%

      Publié: 18 July 2023, 2:00am CEST
      Review of FOSS4G 2023 Introduction

      FOSS4G 2023 was held in Prizren, Kosovo and there were 800+ attendees from 120+ countries. This was a great attendance despite Kosovo not being the easiest place to get to, especially if you were me. I had booked flights to and from Belgrade, Serbia because they were a relatively good times for me (I am missing being only 1 hour from a London airport). It looked like an easy 4 hour drive from the airport to Prizren. Then about a fortnight before the conference Kosovo closed it border to Serbian registered cars! A subsequent check all showed that most of the hire companies wouldn’t let you drive one of their cars over a border (and apparently despite the Serbian Government’s claims they considered Kosovo a separate country). So I fell back on the 9 hour overnight bus trip, which wasn’t as bad as it could have been but did mean I started the conference already somewhat sleep deprived.

      Sort of Historical Side Note

      When I was at school learning Geography all of this area was called Yugoslavia and it was behind an “iron curtain” so we knew little about it and cared even less (it was not on the exam). In history it was covered by the break up of the Ottoman Empire and the meddling of Bismarck as an “honest broker” at the 1878 Congress of Berlin (as I recall he rigged the Balkans in such a way as to start World War I, but history O-Level was a long time ago). So you can already see that there is a long a complex history and geography in the region. It became more complex in the 1990s when Yugoslavia broke up in a series of bloody conflicts, which I remember from the evening news. Kosovo only really came to my attention in 2008 when I was walking through New York with James Macgill and his kids and we saw a large group of cars flying large red flags with double headed eagles on them (and the one thing I retained from my history lessons is the ability to spot a double headed eagle at 200 metres). These were Kosovans celebrating the declaration of independence being proclaimed.

      A man holding a red flag

      So squabbling about car number plates was pretty peaceful really. Fortunately, for us most of KFOR (the UN/Nato peace keeping force) had gone home, except for some in the Northern predominately Serb areas where they were out keeping the piece over disputed elections for city mayors. This meant we could use their old base as a conference venue, which was great except for the lack of lifts.

      Cool talks

      This is a list of talks I found particularly interesting or fun and that stuck in my mind long enough to remember for this post. There were lots of great talks that I either failed to see because the room was too full or was too hot for my brain to have taken in the details, so I’m looking forward to the videos coming out so I can refresh my memory later.

      • Neiene Boeijen Let’s put it on the map!
        • Interesting discussion on why graphic designers shouldn’t make maps and geographers shouldn’t design user interfaces
      • Benjamin Trigona-Harany Aircraft trajectory analysis using PostGIS
        • Explains how PostGIS handles trajectories which are really just a Linestring with MZ values on the points where M increases along the line
        • We can create a foreign table based on a foreign “server” that converts to a REST API call in the background this allows real time mapping filtered by the bounds of the map and any other filters the API can handle.
      • Jody Garnett and Andrea Aime GeoServer used in fun and interesting ways & State of GeoServer
        • As usual Andrea and Jody were presenting way too many talks including this useful review of what GeoServer is capable of in production and a review of new features in GeoServer for this year.
      • Iván Sánchez Ortega Gleo
        • I was going to say this is a new WebGL mapping library, but apparently Iván has been going on about this for 8+ years now. Any way there is lots of object orientated style javascript code in there so you can extend your semi-transparent markers with bouncing. I don’t think it’s quite cool enough for me to start learning JavaScript or WebGL but the demo with 10,000 randomly coloured bouncing map markers is fun in a <blink> sort of way.
      • Sanghee Shin Let’s defense my country using FOSS4G!
        • Discussed how South Korea is modernising its military mapping with GeoServer, PostGIS, Cesium and OpenLayers, which makes me feel better about knowing North Korea is using GeoServer and PostGIS too.
      • Andrea Aime Processing and publishing Maritime AIS data with GeoServer and Databricks in Azure
        • Andrea standing in for Nuno discussed how to handle 1.5 Billion records in GeoServer. Looking at the AIS ship location data over 7 years at second intervals (I think) and how you could get GeoServer to display the relevant data in a fast way.
      • Logan Williams Investigating war crimes, animal trafficking, and more with open source geospatial data
        • Logan is a Bellingcat reporter who uses open source tools to look at open source data to help confirm stories. For example he described how they looked at tracking a GRAD missile launcher from Russia to Ukraine before Malaysian Airliner was shoot down. This included spotting scuffs on the road and distinctive power lines in posted dash camera footage of the convoy.

      Lo que os vamos a mostrar es cómo cambia de manera exponencial la velocidad de trabajo de tener nuestros datos en un formato como el shapefile a hacerlo con una base de datos espacial. H2 es una base de datos ligera, muy fácil de usar y que en nuestro caso va directamente incluida en gvSIG Desktop, por lo que no requiere ninguna instalación. Se basa en ficheros, por lo que distribuir una base de datos de H2 es tan sencillo como compartir un determinado fichero.

      En el ejemplo que se muestra en el vídeo vamos a trabajar con una capa del denominado SIGPAC (una especie de Catastro agrícola) de la provincia de Valencia y que contiene aproximadamente 2 millones de registros.

      Hemos decidido no cortar el vídeo para que veáis que lo único que demora es el paso inicial de exportar el shapefile a la base de datos, por lo que podéis ver hasta el minuto 2:20 y luego pasar al minuto 17, donde ya tenemos la misma información en ambos formatos y se realiza la comparativa en sí. Vuestros problemas para manejar volúmenes de datos grandes, sin requerir instalar nada adicional a vuestro SIG de escritorio… ya se han resuelto.

      Publié: 7 July 2023, 7:21am CEST

      Among the many tools available to gvSIG Online users, there are those related to enumerations. These types of functionalities are extremely useful for data maintenance, as they allow us to define the possible values for a field. They become even more useful when using gvSIG Mapps integrated with gvSIG Online, as when capturing or updating information using the mobile application, these fields will display dropdown menus for easily selecting the corresponding value for each recorded element.

      Enumeration lists can be added, modified, or deleted from the administration area of gvSIG Online. We can create a list from scratch or instruct gvSIG Online to automatically generate it based on the unique values available in that field. Interesting, right?

      Once an enumeration is created, we can also assign it to other fields in other layers. Even more interesting, isn’t it?

      When editing a published layer in a project, these fields will display a dropdown menu with the elements that make up the list, and one of them can be selected to assign it as an attribute of a map element, if it is of type “enumeration,” or multiple elements if it is of type “multiple enumeration.”

      And, as we mentioned earlier, in gvSIG Mapps, we would automatically have our dropdown menus ready to facilitate data collection in the field.

    • sur OGC Compliance Certification Available for v1.0 of the OGC API – Processes Standard

      Publié: 6 July 2023, 3:00pm CEST par Simon Chester

      The Open Geospatial Consortium (OGC) is excited to announce that the Executable Test Suite (ETS) for version 1.0 of the OGC API – Processes – Part 1: Core Standard has been approved by the OGC Membership. Products that implement the Standard and pass the tests in the ETS can now be certified as OGC Compliant.

      The OGC API – Processes Standard supports the wrapping of computational tasks into executable processes that can be offered by a server through a Web API and be invoked by a client application. Typically, these processes combine raster, vector, coverage, and/or point cloud data with well-defined algorithms to produce new information. Examples of computational processes that can be supported by implementations of this Standard include vector data analysis, imagery analysis, and various types of Artificial Intelligence (AI) enhanced analysis. 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.

      Implementers are invited to validate their products using the new test suite, which is available on the OGC validator tool. Testing involves submitting the endpoint of an OGC API – Processes implementation to be assessed. The validator tool sends the appropriate requests to the endpoint of the implementation and then evaluates the responses. These tests typically take only 5-10 minutes to complete. Once a product has passed the tests, the implementer can submit an application to OGC for use of the OGC Compliant trademark on their product. 

      To support developers with implementation of the standard, GeoLabs ZOO-Project 2.0 and Ecere GNOSIS Map Server 1.0 have been designated as reference implementations of the standard after the software products successfully passed the compliance tests. 

      The OGC Compliance Program offers a certification process that ensures organizations’ solutions are compliant with OGC Standards. It is a universal credential that allows agencies, industry, and academia to better integrate their solutions. OGC compliance provides confidence that a product will seamlessly integrate with other compliant solutions regardless of the vendor that created them. 

      More information about the OGC compliance process is available at ogc.org/compliance. Implementers of version 1.0 of the OGC API – Processes – Part 1: Core Standard – or other OGC Standards – are welcomed to validate their products using the OGC validator tool.

      Entre las muchas herramientas que los usuarios de gvSIG Online tienen disponibles se encuentran las relacionadas con enumeraciones. Este tipo de funcionalidades son extremadamente útiles para el mantenimiento de los datos, ya que nos permiten definir los valores posibles de un campo. Doblemente útil si utilizamos gvSIG Mapps integrado con gvSIG Online, ya que a la hora de capturar o actualizar información con la aplicación móvil, en esos campos se nos mostrarán desplegables para elegir fácilmente el valor que corresponde a cada elemento relevado.
      Los listados de enumeraciones se pueden añadir, modificar o eliminar desde el área de administración de gvSIG Online. Podemos crear un listado desde cero o bien decirle a gvSIG Online que lo genere automáticamente a partir de los valores únicos disponibles en ese campo. ¿Interesante, verdad?.
      Una vez creada una enumeración también podemos asignársela a otros campos de otras capas. ¿Más interesante aún, no?
      Cuando se inicie la edición de una capa publicada en un proyecto, en estos campos se desplegarán el listado con los elementos que conforman el listado y se podrá seleccionar uno de ellos para asignarlo como atributo de un elemento del mapa,si es del tipo «enumeración», o varios si es de tipo «enumeración múltiple».
      Y, como ya hemos comentado, en gvSIG Mapps tendríamos automáticamente nuestros desplegables listos para facilitar la toma de datos en campo.

      Vicente, Pedro-Juan, and me started this blog in 2006. Back then blogs were the best way to create content and share knowledge. It was the times of RSS, Google Reader, social bookmarking through del.icio.us, and pictures on Flickr. Very different from these days of micro-blogging, quick videos, influencers moving from one platform to another chasing their viewers' attention and money, newsletters under paywalls, etc.

      We stayed for a few months in a self-hosted Drupal CMS but maintaining it was a pain, so we moved to a managed Wordpress where we lived most of the time. Wordpress offered an excellent balance to get us writing without much hassle, keeping our domain, and very infrequent ads. Finally, last year I migrated the content to Hugo, a static generator, to save some costs, but the decline in writing started in 2018, so it is OK to close this project formally.

      I will keep the blog code and content on a GitHub repository at [https:]] where we have posts in Markdown since 2007, and everything is hopefully for ever available in the web archive at [https:]] . I will probably copy my posts to my website.

      Needless to say that we are forever grateful to those that encouraged us to write here. I had a lot of fun maintaining the website and writing content for everyone else. We are easy to find on the Internet, so please contact us anytime!

      Publié: 5 July 2023, 4:39pm CEST par Simon Chester

      From June 5-9, almost 200 geospatial innovators, influencers, and leaders from across the globe attended OGC’s 126th Member Meeting – with 100 more attending virtually. Hosted by GEOHuntsville at the beautiful Huntsville Botanical Garden in Alabama, USA, meeting attendees spent the week discussing the latest geospatial innovations and hearing how geospatial is transforming organizations and industries across the globe.

      The meeting was additionally sponsored by Hexagon, OpenSensorHub (Botts Innovative Research and GeoRobotix), Ethar, Womble Bond Dickinson, and Compass-HSV.

      The week saw the usual abundance of Standards Working Group (SWG) and Domain Working Group (DWG) meetings, networking & social events (including a fantastic Sunday pre-meeting gathering at the Signals Museum, hosted by Ethar), two award presentations – a Lifetime Achievement Award as well as the new Community Impact Award – and several special sessions, including a Space Standards ad hoc, an Open Science Summit, a Portrayal Workshop, a Connected Systems track, a Defense and Intelligence Track, and a Climate Workshop.

      The full agenda for the 126th OGC Member Meeting is available here. Read on for an overview of the best bits, below.

      OGC CEO, Dr. Nadine Alameh (L), OGC CSO, Scott Simmons (M), and Stan Tillman from meeting sponsor, Hexagon. Opening Session

      Opening the meetings on Monday morning was David Lucas, the Executive Director of host GEOHuntsville, who welcomed attendees and provided event context. This was followed by a welcome from the City of Huntsville Mayor, Tommy Battle.

      Next, we heard from Stan Tillman, of meeting sponsor Hexagon, who provided information on the company with specific information regarding Hexagon Digital Reality capabilities. Dr. Chris Tucker, representing additional meeting sponsors OpenSensorHub participants Botts Innovative Research and GeoRobotix, then highlighted the upcoming session on Tuesday for Connected Systems.

      OGC CEO Dr. Nadine Alameh then provided a CEO Welcome and described the value of recent organizational changes in OGC. Prashant Shukle, Chair of the OGC Board of Directors then gave a greeting from the Board and highlighted a commitment by the Board to more actively participate in OGC activities.

      OGC CEO, Dr. Nadine Alameh (L), with Patty Mims, Director of Global National Government, Esri

      Nadine’s regular fireside chat followed, this time with Patty Mims, Director of Global National Government, Esri. As has become the trend for these chats, they discussed the motivation for joining the geospatial industry as well as provided advice for others to join and succeed in the community.

      Trevor Taylor, Senior Director, Member Success and Development of OGC, welcomed new members and refreshed attendees on the new OGC membership model that’s now in place for new members.

      I, Scott Simmons, Chief Standards Officer of OGC, then wrapped up the session by providing some logistics information for the week and describing the process to be followed in the coming weeks-to-months to roll out of the new Technical Committee Policies and Procedures. I also described the new tools in place for submitting presentation requests and special sessions for meetings.

      Special Sessions

      The Space Standards ad hoc continued the discussion from the 125th Member Meeting concerning where OGC should work in Space Standards, which identified a number of topical areas for Standardization as well as existing Standards covering some portions of those areas. Participants at this session identified areas of focus and proposed a new Domain Working Group (DWG) that will begin the chartering process in the coming weeks. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      The Open Science Summit focused on a proposal for a new OGC Pilot project for an Open Science Persistent Demonstrator. NASA, Google, and the European Space Agency (ESA) each presented information on their own platforms. The Summit then followed with an open discussion on which other platforms might exist and what should be included. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      Marge Cole, Director, Collaborative Solutions and Innovation Programs, OGC, speaking at the Open Science Summit

      The Portrayal Workshop: OGC has been modernizing its Standards for the portrayal of geospatial data. Numerous other communities have dependencies on the OGC Standards portfolio and need to understand the applicability of these newer Standards and how they replace the functionality of legacy Standards. The Portrayal Workshop was organized jointly with the International Cartographic Association (ICA) and was run to develop an OGC Technical Paper for “Standards supporting cartographic best practices.” OGC Members can access the presentations and a recording on this page in the OGC Portal.

      The Connected Systems track: OGC has chartered new working groups to update and create a RESTful implementation of sensor-related Standards. The Autonomy, Sensors, Things, Robots, and Observations (ASTRO) Domain Working Group (DWG) investigates requirements and standardization targets and the Connected Systems Standards Working Group (SWG) is building the new Standards. These groups held a full-afternoon track to describe the intent of the Connected Systems API, the relationship of the work to other OGC APIs and the Sensor Web Enablement (SWE) Standards, and to demonstrate how the new Standards work in practice. OGC Members can access the presentations and a recording on this page in the OGC Portal, as well as the Demonstration here.

      The Defense and Intelligence Track: The Defense and Intelligence DWG takes a broad look at the use of Standards in defense/intelligence operations as well as the requirements for interoperability that can be solved, in part, by Standards. The DWG held a full-afternoon track to explore the fundamental concepts and thus bring participants to a baseline of understanding. The session also explored where OGC members could contribute to new Standards in imagery & motion imagery as well as Space. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      The Climate Workshop: OGC’s Climate Resilience DWG organized a Climate Workshop for Friday where the DWG defined the nature of its mission for resilience as the “ability of a system to compensate for impacts.” The session highlighted numerous initiatives underway in OGC and other organizations, framing them in terms of opportunities for impact. The workshop also expressed a proposed timeline for the next OGC Climate Resilience Pilot. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      Today’s Innovation/Tomorrow’s Technology and Future Directions

      The popular Today’s Innovation/Tomorrow’s Technology and Future Directions session focused on ongoing OGC research and deployment of the nascent OGC Rainbow (borne from the OGC Definitions Server), which represents the state-of-the-art in enabling semantic interoperability. 

      OGC Rainbow is a web-accessible source of information about things (“Concepts”) that the OGC defines or that communities ask the OGC to host on their behalf. OGC Rainbow comprises several registries linked to common access for both human- and machine-readable representation of the data. 

      The OGC Definitions Server has long provided Coordinate Reference System (CRS) definitions, terminology definitions used in OGC Standards, and code lists for various domains of interest. As the capability of the OGC Rainbow increases, OGC will be registering requirements from Standards, representation of the OGC Building Blocks, and linkages to other authoritative registries. OGC Rainbow will improve consistency in the geospatial standards community and allow for expedited development of new capabilities.

      Dr. Ingo Simonis and Dr. Rob Atkinson of the OGC COSI Program explained the capabilities and use cases of the OGC Rainbow and moderated open discussion amongst participants regarding the use of OGC Rainbow. OGC Members can access the presentations and a recording on this page in the OGC Portal. Stay tuned to the OGC Blog for more on the OGC Rainbow soon.

      Dinner & Awards

      Attendees of the Executive Dinner had the unforgettable experience of dining under an actual Saturn V Rocket

      At the dinner, two awards were presented: Dr. Jeff de La Beaujardiere received the OGC Lifetime Achievement Award; and Natural Resources Canada received the inaugural OGC Community Impact Award.

      Dr. Jeff de La Beaujardiere was selected for the Lifetime Achievement award due to his long standing leadership, commitment, and support for the advancement and uptake of standards used for the dissemination of Earth Science information. In the OGC community, Jeff is best known as the Editor of the OGC Web Map Service (WMS) Specification: a joint OGC/ISO Standard that now supports access to millions of datasets worldwide. OGC WMS was the first in the OGC Web Services suite of Standards and is the most downloaded Standard from OGC. But most importantly, the OGC WMS Standard truly revolutionized how geospatial data is shared and accessed over the web. Jeff was also a major contributor to other OGC Standards, including the OGC Web Services Architecture, the OGC Web Map Context, OGC Web Terrain Service, and OGC Web Services Common. 

      The new OGC Community Impact award highlights the importance of collaboration, volunteering time and energy, advancing technologies and standards, raising awareness, and helping solve critical issues across the geospatial community. Natural Resources Canada exemplifies all of these qualities through their championing of innovation and standards. They consistently go above and beyond as both an OGC Member, and as a member of the wider geospatial community.

      Wrapping up the week, I opened the Important Things session with a rapid, 15-minute summary of the entire meeting week that included slides and content from a large number of Working Group sessions. OGC Members can access the presentations and a recording on this page in the OGC Portal. 

      The Important Things session then featured a discussion on how much OGC SWGs should accommodate developer interests and existing applications vs. optimizing their Standards work to meet the Standard requirements. OGC Members then discussed the issue and provided numerous examples of the conflict in current work. OGC Members can read the notes from the session in the Etherpad “Important-Things-2023-06”.

      The Closing Plenary, though mostly focused on presentations and voting, also saw several presentations. Carsten Rönsdorf of Ordnance Survey provided a summary of the effectiveness of the model-driven standard authoring that was used for CityGML 3.0 and is now underway with MUDDI. Ali Al’Awaji highlighted the success of recent cooperation between his organization, the General Authority for Survey and Geospatial Information (GASGI) and OGC. The remainder of the session advanced a number of Standards, SWGs, and documents toward vote or publication.

      Wow what an adventure, Jody Garnett here returning from visiting FOSS4G conference and the GeoCat offices. 

      FOSS4G for the People

      The Free and Open Source Software for Geospatial conference was very much a community affair this year. FOSS4G 2023 was a chance to meet and speak with peers from the GeoNetwork and GeoServer projects and connect with companies and the B2B activity.

      Indeed GeoCat attended with a booth, and a few things to hand out, and conversation. Our booth was near the speakers, so we would sneak over and turn down the music so we could talk. And we talked a lot – so many nice people! With all the talking I do not beleive I opened my laptop to show off our products once the entire week.

      It was a pleasure seeing Jeroen and Florent comfortable on the massive stage providing an 1:250k scale overview of GeoNetwork activities.

      I had a good workshop on GeoServer with Ian Turton to start, and some entertaining presentations with Andrea over the course of the week. The GeoServer Feature Frenzy and GeoServer used in fun and interesting ways were real highlights with great audience response.

      This year I only had one outreach presentation, on the topic of OSGeo values, with Tom.

      With the conference hosted by OSGeo and the FLOSSK regional open source group it appeared attendees were already comfortable with open source as a concept.  However OSGeo values go a bit further than just a license – looking at a project’s sustainability and other risk factors also.

      Presentation:

      GeoCat Bennekom

      It is always a pleasure to visit the GeoCat office, and customers, in the Netherlands. Everyone was full of ideas and opportunities, and pushing hard on GeoCat Bridge for ArcGIS.

      The office garden is amazing, exploring outside of the village showed a landscape surprisingly dry from a regional drought.

      The next activity GeoCat is attending is the Bolsena Code Sprint. Please consider yourself invited!

      There are number of regional foss4g events coming up and we look forward to more opportunities for advocacy and meeting new customers.

      Publié: 4 July 2023, 7:57am CEST

      Como parte de uno de los proyectos que estamos abordando con la Suite gvSIG, la IDE turística de la Mancomunidad del Pla de Mallorca, hemos realizado un inventario turístico en el que se ha partido de datos existentes y se ha realizado labor de toma de datos en campo (con gvSIG Mapps). La novedad de dicho inventario es que es pionero en la adopción de la Norma UNE 178503 para representar las distintas capas de datos georrefenciados.

      La UNE 178503:2022 “Semántica aplicada a destinos turísticos inteligentes”, define una semántica base que permite representar la información relevante en la que se conforma el destino turístico (destino turístico, recursos turísticos dentro del destino, experiencias de viaje), asegurando la interoperabilidad de sus plataformas turísticas y de la ciudad y el territorio entre sí y con desarrollos de terceros.

      Esta adopción de la Norma ha conllevado un trabajo previo de análisis de datos existentes y de la propia Norma permitiendo, entre otras cosas, identificar posibles términos que no están incluidos en la norma UNE 178503:2022 o campos que no aplican a las características de la Mancomunidad. De este modo se ha conseguido una adopción y adaptación a la realidad particular del destino del Pla de Mallorca que ha acabado reflejado en el modelo de datos de la Infraestructura de Datos Espaciales.

      Por tanto, este proyecto ha conllevado llevar la interoperabilidad de datos geográficos turísticos un paso más allá, tanto en servicios de acceso (WMS, WMTS. WFS) como en semántica y modelo de datos.

      En breve os contaremos más sobre el proyecto y compartiremos la IDE/Geoportal resultante, donde podréis consultar el inventario. Todo ello desarrollado con gvSIG Online para la publicación de datos, gvSIG Mapps para la toma de datos y gvSIG Desktop para el tratamiento de datos.

    • sur Marco Bernasocchi: QField background tracking

      Publié: 29 June 2023, 11:54am CEST

      Years ago, the QField community and its users showed their love for their favourite field app by supporting a successful crowdfunding to improve camera handling.

      Since then, OPENGIS.ch has continued to lead the development of QField with the regular support of sponsors. We couldn’t be prouder of the progress we have made, with plenty of new features added in every major release. This includes major improvements to positioning including location tracking, integration of external GNSS receivers through not only Bluetooth but TCP/UDP and serial port connections, accuracy indicator and constraints, and most recently sensors reading to list a few.

      We are now calling for the community to help further better QField and unlock an important milestone: background location tracking service.

      Pledge now

      Main goal: background location tracking on Android – 25’000€

      Currently, QField requires users to keep their devices’ screen on and have the app in the foreground to keep track of the device’s positioning location. On mobile devices, this can drain batteries faster than many would want to, in environments where charging options are limited.

      This crowdfunding aims at removing this constraint and allow QField – via a background service – to constantly keep tracking location even while the device is suspended (i.e., when the screen is turned off / locked). 

      To achieve this, a significant amount of work is required as the positioning framework on Android will need to be relocated to a dedicated background service. Recent work we’ve done adding a background service to synchronize captured image attachments in QFieldCloud projects armed us with the assurances that we can achieve our goal while giving us an appreciation of the large amount of work needed.

      Some of the benefits

      Running out of battery is the nightmare of most field surveyors. By moving location tracking to a background service, users will be able to improve their battery life considerably and keep focusing on their tasks even if it involves switching to a different app.

      Furthermore, while OPENGIS.ch ninjas remain busy squashing reported QField crashes all year long, there will always be unexpected scenarios leading to abrupt app shutdowns, such as third-party apps, systems running out of battery, etc. To address this, the background service framework will also act as a safeguard to avoid location data loss when QField unexpectedly shuts down and offer users means to recover that data upon re-opening QField.

      Stretch goal 1: background navigation audio feedback 5’000€

      The second stretch goal builds onto QField’s nice fly-to-point navigation system. If the QField community meets this threshold, a new background navigation audio feedback informing users in the field of their proximity to their target will be implemented. 

      The audio feedback will use text-to-speech technology to state the distance to target in meters for a given time or distance interval.

      Stretch goal 2: iOS 15’000€

      The main goal will cover the Android implementation only. Due to being a very low level work we will have to replicate the work for each platform we support. If we reach stretch goal 2 we will also implement this for iOS.

      Pledge now:

      In case you do not see the embedded form you can open it directly here.

      Thanks for supporting our crowdfunding and keep an eye on our blog for updates on the status.

      Funding for the programme was sourced by you, our project donors and sponsors! Note: For more context surrounding our grant programme, please see: QGIS Grants #8: Call for Grant Proposals 2023.

      The QGIS.ORG Grant Programme aims to support work from our community that would typically not be funded by client/contractor agreements. This means that we did not accept proposals for the development of new features. Instead proposals focus on infrastructure improvements and polishing of existing features.

      Voting to select the successful projects was carried out by our QGIS Voting Members. Each voting member was allowed to select up to 6 proposals. The full list of votes are available here (on the first sheet). The following sheets contain the calculations used to determine the winner (for full transparency). The table below summarizes the voting tallies for the proposals:

      A couple of extra notes about the voting process:

      • Voting was carried out based on the technical merits of the proposals and the competency of the applicants to execute on these proposals.
      • No restrictions were in place in terms of how many proposals could be submitted per person / organization, or how many proposals could be awarded to each proposing person / organization.
      • Voting was ‘blind’ (voters could not see the existing votes that had been placed).

      We received 35 votes from 20 community representatives and 15 user group representatives.

      On behalf of the QGIS.ORG project, I would like to thank everyone who submitted proposals for this call!

      Publié: 26 June 2023, 8:20am CEST

      The geocoding plugin of gvSIG Online is a powerful and versatile tool that allows us to search for places and locate them on the map. At the user level, its operation is extremely simple. Once the search string is entered, a list of possible candidates is displayed. At the administration level, the most interesting feature is that we can configure and add as many providers/geocoders as we need.

      Of course, the plugin offers functionality for both forward geocoding (locating a place based on a search string) and reverse geocoding (finding the address by marking a position on the map).

      From the administration panel, in the list of search providers, you can assign a category (to group the results of that provider under a separator) and assign an icon that will mark each of the suggested locations. Then, depending on the characteristics of each provider, different parameters may be required for them to function. Examples of providers include Nominatim from OpenStreetMap, Google Maps, custom layers such as points of interest or street data, etc.

      The plugin has very interesting options, such as configuring and establishing the priority order in which the results obtained from each of the providers used in the searches will be displayed.

      And, of course, it is possible to configure custom providers for each territory, as we have done in various projects. Examples include Cartociudad in Spain or the Geocoder of the IDE in Uruguay.

A nivel de usuario su funcionamiento es extremadamente simple, una vez introducida la cadena de búsqueda nos aparece un listado con los posibles candidatos. A nivel de administración, lo más interesante, es que podemos configurarlo y agregar tantos proveedores/geocodificadores como necesitemos.

      Por supuesto el plugin dispone de funcionalidad tanto de geocodificación directa (la localización de una ubicación mediante una cadena de búsqueda) como geocodificación inversa (averiguar la dirección marcando una posición en el mapa).

      Desde la parte de administración, en la lista de proveedores de búsqueda se les puede indicar una categoría (para englobar los resultados de ese proveedor bajo un separador) y se les puede asignar un icono que marcará cada una de las sugerencias propuestas . Luego, según las características de cada uno, se requerirán unos parámetros u otros para que puedan funcionar. Ejemplos de proveedores: Nominatim de OpenStreetMap, Google Maps, capas propias de – por ejemplo – puntos de interés o callejero, etc.

      El plugin tiene opciones muy interesantes, como configurar y establecer el orden de prioridad en el que se mostrarán los resultados obtenidos de cada uno de los proveedores utilizados en las búsquedas.

      Y, por supuesto, se pueden configurar proveedores propios de cada territorio, como así hemos realizado en diversos proyectos. Ejemplos: Cartociudad en España o el Geocoder de la IDE de Uruguay.

      On June 12-14, 2023, OGC held its 2023 Tiling Interfaces Code Sprint at OGC Strategic Member NGA’s Moonshot Labs in St. Louis, Missouri. The code sprint focused on a select set of Application Programming Interface (API), database, and encoding standards related to map tiles. An API is a standard set of documented functions that expose the capabilities supported or data offered by an application, or service to other applications. 

      OGC code sprints are collaborative and inclusive events that support the development and refinement of open standards by providing software developers the time and space to focus on projects that implement the standards. 

      By experimenting with emerging ideas in the context of geospatial standards, OGC code sprints help improve interoperability of existing standards by experimenting with new extensions or profiles, and building or enhancing software products to implement the standards. 

      In addition, the sprints’ mentor streams provide developers with a helping hand when learning how to use the standards and projects so that they can build a working understanding of them that will last beyond the duration of the sprint.

      The mentor stream at the Tiling Interfaces Code Sprint included three entry-level tutorials that used practical use-cases to introduce participants to the standards. One tutorial focused on how to serve vector tiles using the OGC API – Tiles standard, while another focused on compliance testing, and the third provided an overview of a web-based product that implements several OGC standards.

      The 2023 OGC Tiling Interfaces Code Sprint focused on the following Standards and specifications:

      Results

      At its peak, the code sprint had 50 concurrent active users participating remotely across multiple channels on the code sprint’s online platform. In-person participation saw a dozen participants from NGA, OGC, US Army Geospatial Center, UK Defence Science & Technology Laboratory (Dstl), Universitat Autònoma de Barcelona (CREAF), Pixalytics Ltd., Compass, FlightSafety International, and University of Maryland. 

      Screenshots of a selection of applications deployed for the code sprint are shown below.

      During the code sprint, personnel from the US Army Geospatial Center (AGC) presented the Releasable Basemap Tiles (RBT) product which has been in development at AGC (Figure 6). The presentation enabled participants to identify an approach for how QGIS and GDAL could support workflows that involve the downloading of vector tiles and map tiles from an OGC API and the storage of the tiles in a GeoPackage.

      What did we learn?

      The following are some of the lessons learned during the code sprint, and recorded by participants on the final day of the code sprint. 

      There is a need for further developer guidance documents for implementing OGC API – Tiles, particularly with regard to the placement on tileset resources. Such guidance should include clarification on the handling of relation types such as ‘conformance’ that can be represented as simple string literals and also as URLs.

      There is a need to make sure there exists a well-documented user journey for people that want to use OGC API – Tiles through QGIS. For example, documentation to take a beginner from their first line of code to a more advanced stage.

      Although some work has been done on vector tiles within OGC, more work is needed to advance the specification towards becoming an OGC Standard. Some of the work that could be carried out includes, for example, development of a Best Practice document. RBT could provide a foundation for such a Best Practice.

      For future code sprints, it may be necessary to introduce participants to the basics of the specifications that are in focus for the code sprint ahead of the event. Further, it would be helpful to participants such as students to have specific instructions to help participants prepare for the code sprint.

      Conclusions and Recommendations

      The code sprint met all of its objectives and achieved its goal of supporting the implementation of open geospatial standards within the developer community. Furthermore, the code sprint provided an environment for development and testing of prototype implementations of open standards and a starting point for developers to learn about the draft and approved standards, as well as their implementations.

      The participants identified the following recommendations at the conclusion of the code sprint:

      • A future code sprint that includes the OGC CDB Standard should examine how vector tiles could be embedded in such a data store.
      • AGC is interested in how the World Mercator coordinate reference system (reference EPSG:3395) could support vector tiles in a GeoPackage. The question for future experimentation is whether this could be specified so that it can be implemented by any developer.
      • The application of OGC API – Tiles in partitioning and indexing content from an implementation of the OGC SensorThings API standard and the OGC API – Connected Systems candidate standard could be explored in a future code sprint.
      • An initiative to develop content for the OGC e-learning resource and the OGC Compliance Program could help improve interoperability between implementations of OGC Standards.
      • Although OGC API – Tiles is an approved standard, there is some work to do around addressing interoperability issues in the different implementations (see for instance this Issue on the OSGeo gdal GitHub.

If you are within the path of totality, you will see the Sun completely blocked out by the Moon for about two minutes. If you want to preview what the solar eclipse might look like for different locations then

    • sur gvSIG Team: Inventario de empresas y vertidos en áreas industriales con gvSIG Online

      Publié: 23 June 2023, 7:57am CEST

      Para el Ayuntamiento de Náquera se ha desarrollado un conjunto de herramientas, integradas con gvSIG Online con el objetivo de llevar a cabo la creación y gestión del inventario georreferenciado de las empresas ubicadas en las áreas industriales del municipio.

      La herramienta web sirve para la captación de información de empresas (sector de actividad, volumen de negocio, número de empleados, características de los residuos, tomas de agua, salidas de emergencias…) situadas en los polígonos industriales y para su integración en un visor de mapas de gvSIG Online con la geolocalización de dichas empresas.

      Parte de la información es introducida por las propias empresas mediante diversas herramientas desarrolladas con este objetivo. Por otro lado, el sistema dispone de opciones de validación de la información para los técnicos municipales. Además, la solución desarrollada también posee funcionalidad para gestionar el registro de empresas, de forma que puedan acceder al sistema y modificar sus datos.

      Después de la introducción de los datos y validación por parte del Ayuntamiento la herramienta genera una capa que permite consultar las fichas de empresas registradas en la herramienta web desde el geoportal de áreas industriales de Nàquera. Al pulsar en el mapa, se muestra la información básica de la empresa, teniendo la opción de consultar la ficha completa de cada una de las empresas.

      Por otro lado, la herramienta permite consultar los diferentes sectores de empresas por actividad, activando o no la visibilidad de cada sector, de todos los sectores o de aquellos que se seleccionen.

      Del mismo modo que se rellenan los datos de la ficha de empresa, existe la opción de rellenar la información correspondiente a una ficha de control de vertidos. Estas fichas de control de vertidos pueden ser consultadas desde el geoportal de áreas industriales, siempre con acceso restringido. Cada empresa está asignada a Estaciones de Muestreo, de forma que cuando se detecta una incidencia en una estación de muestreo se pueden listar todas las empresas vinculadas a dicha estación de muestreo.

      Un ejemplo más de como gvSIG Online se ha convertido en una solución idónea para gestionar la información de un municipio, en este caso de sus áreas industriales.

    • sur gvSIG Team: Infraestructura de Datos Espaciales de Albacete. La Suite gvSIG como solución a la gestión integral de la información geográfica municipal

      Publié: 22 June 2023, 8:08am CEST

      El proyecto de implantación de la IDE de Albacete merece más de un post, por su ambición y resultados. De momento comenzamos compartiendo una presentación del alcance y trabajo desarrollado para convertir la Suite gvSIG en la solución a la gestión integral de la información geográfica municipal.

      Algunos apuntes antes de dejaros con la presentación… se ha utilizado el control de versiones de gvSIG Desktop para las actividades de edición multiusuario de la información cartográfica, se ha incorporado gvSIG Mapps como herramienta de toma de datos en campo integrada con gvSIG Online, se ha realizado la integración con el gestor de expedientes SEGEX de SEDIPUALBA, se ha desarrollado una herramienta de localización y ruteo para el cementerio municipal, plantillas varias para impresión, integración con el padrón – ahora georreferenciado -, adaptación a RT de Inspire, un completo y versátil geocoder, acceso a Catastro con datos protegidos a nivel interno,…

      El proyecto de implantación de la IDE de Albacete es un ejemplo para cualquier administración local que quiera poner en marcha una solución similar. Un ejemplo, también, de por qué la tecnología gvSIG se ha convertido en un referente en el sector de la geomática.

    • sur gvSIG Team: Implantación de la Infraestructura de Datos Espaciales de Alzira. Proyectos en gvSIG Online

      Publié: 21 June 2023, 8:01am CEST

      El Ayuntamiento de Alzira es otra más de la administraciones locales que ha apostado por la Suite gvSIG como la tecnología base para poner en marcha su Infraestructura de Datos Espaciales. Un proyecto que, más allá de todos los visores de mapas internos, en poco tiempo ha permitido publicar diversos geoportales como los de planeamiento, infraestructuras, plan local de quemas, etc.

      Es interesante reseñar que además de la propia IDE montada con gvSIG Online, se ha integrado gvSIG Mapps para la toma de datos en campo y el gestor de expedientes de Indenova. Entre los desarrollos a medida, destaca el proceso que permite generar de forma automática la cédula urbanística.
