    • sur Sean Gillies: Bear training week ~6 recap

      Publié: 20 August 2023, 8:14pm CEST

      For fun I'm using the bitwise complement operator ~ in the title of this post. Race week is week ~0. On Monday, it was 6 weeks to race week. I'm starting to feel fit, close to my 2020-2021 form.

      The numbers for the week:

      • 16 hours, 54 minutes

      • 71 miles

      • 12,165 feet D+

      I've run six days in a row and my shortest run was today's: an hour and 20 minutes. I went out for five hours in Rocky Mountain National Park on Wednesday, two hours in Lory State Park on Friday, and five and a half hours at Horsetooth Open Space on Saturday.

      Towers trail tailgating

      A bear was active around Towers Trail yesterday, but successfully avoided me. According to some bikers, it crossed the trail behind my back near the top during my first lap. If I'd turned when I heard them shouting, I might have seen it. I know there are bears up there, but have never seen one while I've been on the trail. It's a good time to be filling up on chokecherries, that's for sure.

      Next week I'm going to increase my training volume a little more. Instead of two 5.5 hour runs, I'll aim for 3 x 4 hours.

    • sur Free and Open Source GIS Ramblings: I’ve archived my Tweets: Goodbye Twitter, Hello Mastodon

      Publié: 20 August 2023, 4:38pm CEST

      Today, Jeff Sikes @box464@firefish.social, alerted me to the fact that “Twitter has removed all media attachments from 2014 and prior” (source: [https:]] ). So far, it seems unclear whether this was intentional or a system failure (source: [https:]] ).

      Since I’ve been on Twitter since 2011, this means that some media files are now lost. While the loss of a few low-res images is probably not a major loss for humanity, I would prefer to have some control over when and how content I created vanishes. So, to avoid losing more content, I have followed Jeff’s recommendation to create a proper archival page:

      [https:]]

      It is based on an export I pulled in October 2022 when I started to use Mastodon as my primary social media account. Unfortunately, this export did not include media files.

      Btw, a recent study published on Nature News shows that Mastodon is the top-ranking Twitter replacement for scientists.

    • 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.

      Participe do State of the Map Curitiba 2023

      Faça Parte do State of the Map Brasil 2023: Conectando-se ao Futuro do Mapeamento Geoespacial!

    • 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.

      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.

    • sur Jackie Ng: Announcing: MapGuide Maestro 6.0m12

      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 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.

      Publié: 26 July 2023, 5:18pm CEST

      We are happy to announce that OSGeo kindly extended an invitation to have a QGIS contributor meeting joining the OSGeo Community Sprint 2023 during the Big Data from Space 2023 conference in Vienna.

      The 26th QGIS Contributor Meeting will be held from Monday, November 6th to Thursday, 11th.

      • Where: Austria Center Vienna [https:]]
      • When:  Mon 2023-??11-06 09:00 -?? Thu 2023-11-09 12:00

      For more details and to sign up, please visit the corresponding OSGeo announcement page.

      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.

    • sur Jackie Ng: Announcing: mapguide-react-layout 0.14.9

      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.

    • sur Ian Turton's Blog: How much fun was FOSS4g 2023?

      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.

      Si queréis optimizar vuestro trabajo a la hora de trabajar con información geográfica… no os perdáis este vídeo, sobretodo si manejáis capas de información grandes, con cientos de miles o millones de registros, lo que siempre da problemas de velocidad a la hora de hacer zooms, desplazamientos, etc.

      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.

      Last month I got to record a couple podcast episodes with the MapScaping Podcast’s Daniel O’Donohue. One of them was on the benefits and many pitfalls of putting rasters into a relational database, and the other was about real-time events and pushing data change information out to web clients!

      TL;DR: geospatial data tends to be more “visible” to end user clients, so communicating change to multiple clients in real time can be useful for “common operating” situations.

    • sur gvSIG Team: Working with Enumerations in gvSIG Online (and gvSIG Mapps)

      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.

      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!

      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.

      Open Source Geospatial Foundation

      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:

      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!

      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.

      Para dar solución a estas necesidades se ha implementado gvSIG Online, como plataforma para gestionar todas la información georreferenciada relativa al PITCAN y que, por ejemplo, incluye funcionalidades para generar informes automáticos en distintos formatos. Por otro lado, se ha desarrollado una app integrada con gvSIG Online y basada en gvSIG Mapps con herramientas orientadas a facilitar las consultas a los ciudadanos y visitantes interesados en el Plan de Infraestructuras Turísticas de Canarias.

      Por si queréis echarle un vistazo, la app la tenéis disponible tanto para iOS como para Android.

    • sur gvSIG Team: Planes locales de quemas (PLQ) con gvSIG Online

      Publié: 28 June 2023, 8:00am CEST

      El Plan Local de Quemas (PLQ) es una normativa reguladora fundamental en la gestión del uso cultural del fuego que se aplica en la Comunidad Valenciana, existiendo normativas similares en otras comunidades autónomas.

      Los PLQ están orientados, principalmente, a minimizar los riesgos de incendios forestales. Regulan actividades tradicionales que requieren el uso del fuego como la quema de restos de poda, quema de matorrales, quema de márgenes de cultivo, uso del ahumador en actividades apícolas, etc.

      Estos Planes Locales de Quemas tienen una clara componente territorial, estableciendo zonas de riesgos que establecen las limitaciones para realizar quemas en las distintas parcelas de un municipio.

      Cada vez son más los municipios que implantan gvSIG Online como su solución para gestionar toda la información territorial. Con gvSIG Online es extremadamente sencillo generar un geoportal con el Plan Local de Quemas.

      Os traemos 3 ejemplos de 3 municipios que tienen un geoportal público con el PLQ:

    • sur QGIS Blog: QGIS Grant Programme 2023 Results

      Publié: 26 June 2023, 8:32pm CEST

      We are extremely pleased to announce the 4 winning proposals for our 2023 QGIS.ORG grant programme:

      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!

    • sur gvSIG Team: Geocoder of gvSIG Online. Versatility and power in address searches.

      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.

    • sur gvSIG Team: Geocoder de gvSIG Online. Versatilidad y potencia en las búsquedas de direcciones.

      Publié: 26 June 2023, 8:14am CEST

      El plugin de geocodificación (geocoder) de gvSIG Online es una herramienta potente y versátil que nos permite buscar lugares y ubicarlos en el mapa. 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.

    • 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 iCarto Blog: Creating a Shareable QGIS Project with PostgreSQL/PostGIS Connections

      Publié: 19 June 2023, 5:41pm CEST

      One of the numerous features offered by QGIS is the ability to save our projects. We can store all the specific configurations, layers, styles, analyses, and other aspects in a file, allowing us to return to that point at any time. This is particularly useful when dealing with complex project organization. This functionality is also very helpful for collaborative work, as we can exchange projects with other team members.

      However, when creating a project for sharing, certain aspects need to be taken into account, such as including connections to a database. In this article, we will discuss some interesting key points for accomplishing this.

      Database Connections in QGIS Projects: The Recommended Approach

      Most of the time, when creating a QGIS project with PostgreSQL/PostGIS layers, the data connection details are directly written, including storing the password in plain text within the project.

      When done this way, within the project file created by QGIS with .qgz/.qgs extension, there will be a line like this:

      <datasource>dbname='test' host=localhost port=5439 user='test_user' password='test_user' sslmode=disable key='id' srid=4326 type=Point checkPrimaryKeyUnicity='0' table="public"."cities" (geom)</datasource>

      This approach creates several problems when it comes to deploying the project or sharing it with others:

      • Usernames and passwords need to be shared among several people, making it impossible to establish logical individual or group permissions.
      • If we don’t hardcode the username and password, every person using the project will have to enter the data each time.
      • Passwords are stored in plain text.
      • If the server needs to be changed, for example, from a testing environment to a production one, the project needs to be modified.
      • …

      Although there are some ways to improve this situation, such as using .pgpass, using the Authentication Manager, or using custom embedded scripts within the project, they are not the best options and have issues.

      The best approach, or at least the one we can recommend based on our experience, is to associate the connection details with an identifier (a pre-agreed name) and establish the connection in QGIS using the same identifier.

      PostgreSQL allows achieving this through the Connection Service File. It is a text file located in Linux at ~/.pg_service.conf and in Windows at %APPDATA%\postgresql\.pg_service.conf, and it would look like this:

      
[test]
host=localhost
port=5439
dbname=test
user=test_user
password=test_user
sslmode=disable

# Avoid hardcode the password in prod
[production]
host=my.production.server
port=5432
dbname=my_project
user=my_user

      In QGIS, the connection would be established like this:

      Here, you only need to fill in the connection name and the service name, which will be our identifier (the text within the brackets) in the .pg_service.conf file. This is explained in more detail in the QGIS documentation.

      The advantages of using connections with an identifier are clear and solve the aforementioned problems. One person can prepare the project locally, and then, when moving to production, they only need to send the project and indicate the connection name and parameters that the rest of the team should fill in the .pg_service.conf file.

      Furthermore, since this file is directly managed by libpq, the standard PostgreSQL client library used by 99% of applications, this strategy will work with any other client that needs to use that database connection, not just QGIS.

      For example, in console commands:

      ogrinfo PG:"service=test" cities
psql service=test

      or in QGIS scripts:

      layer = QgsVectorLayer("service=test table=cities (geom)", "Cities", "postgres")
QgsProject.instance().addMapLayer(layer)

      The Service File allows defining numerous parameters, and few of them are mandatory. For instance, if we don’t define the password, any application using libpq will execute a normal workflow to try to discover it: searching in the PGPASSWORD variable, checking the existence of the .pgpass file, or directly prompting us to provide it.

    • sur gvSIG Team: Un vistazo a la Infraestructura de Datos Espaciales de Cullera (IDE)

      Publié: 14 June 2023, 8:21am CEST

      La IDE de Cullera se inició en el área de urbanismo, pero rápidamente se ha extendido a todas las áreas y departamentos municipales. En la actualidad cuenta con decenas de geoportales internos y una serie de visores de mapas públicos, donde consultar información relevante para los ciudadanos y visitantes del municipio.

      Con este post vamos a iniciar una serie de artículos en los que os iremos presentando distintas Infraestructuras de Datos Espaciales implantadas con gvSIG Online, que se está convirtiendo en la solución de referencia para IDEs con software libre.

      Vamos a repasar solo algunos de los geoportales públicos:

      • Turismo: Es el geoportal principal que recopila información relativa al turismo. Agrupa un extenso conjunto de información como oferta hotelera, puntos y zona de Wi-Fi, gastronomía, museos, rutas y sendas turísticas, playas,…
      • Movilidad y transporte: Permite consultar información relativa a movilidad como estacionamientos, carriles bici, líneas de autobús, puntos de carga eléctrica,…
      • Deportes: Este geoportal está orientado a mostrar los recorridos de diferentes eventos deportivos como la Volta a peu a Cullera, el triatlón, la San Silvestre,…
      • Agricultura y actividades cinegéticas: Contiene información de usos del suelo, bancos de tierras,…
      • Servicios municipales: Visor de mapas con información de dotaciones municipales como centros sanitarios, bibliotecas, instalaciones deportivas, centros de enseñanza,…
      • Playas: ahora que se acerca la temporada estival aquí se puede encontrar información tan interesante como playas accesibles, infraestructuras, banderas azules…
      • Urbanismo: el inicio de la IDE, con toda la información típica de este tipo de geoportales relativa al urbanismo (calificación y clasificación) y catastro. Es interesante destacar que tiene normativa urbanística asociada a los elementos geográficos.
      • Y más geoportales públicos: infraestructuras, medio ambiente y cambio climático, gestión de residuos, ciudadanía, arqueología, sanidad, fiestas y comercio. Y siguen creciendo…

      La dirección de la página principal de la IDE de Cullera es:

      [https:]]

      El principal contenido de la IDE, además de los servicios de mapas, son sus geoportales. En el siguiente enlace se pueden visualizar todos los visores de mapas actualmente disponibles:

      [https:]]

      También es interesante hacer referencia a que gvSIG Online permite generar “Vistas compartidas” que no son más que URLs que permiten compartir una configuración concreta de un geoportal, en la que hay una serie de capas visibles o invisibles por defecto e, incluso, un determinado encuadre (zona o territorio del municipio visible al entrar).

      Desde la web de turismo del Ayuntamiento de Cullera, accesible en el enlace [https:]] hay vistas compartidas en distintas secciones de esta web: playas, rutas naturales, monumentos… todas estas vistas compartidas enlazan con distintas configuraciones del geoportal de Turismo que forma parte de la IDE.

      Por último, para acabar, indicar que entre las mejoras previstas para los próximos meses está la integración con el gestor de expedientes (SEGEX de Sedipualba) y la incorporación de gvSIG Mapps como app para toma de datos en campo.

    • sur OPENGIS.ch: Unterstützung für WMTS im QGIS Swiss Locator

      Publié: 13 June 2023, 7:42am CEST

      Das QGIS swiss locator Plugin erleichtert in der Schweiz vielen Anwendern das Leben dadurch, dass es die umfangreichen Geodaten von swisstopo und opendata.swiss zugänglich macht. Darunter ein breites Angebot an GIS Layern, aber auch Objektinformationen und eine Ortsnamensuche.

      Dank eines Förderprojektes der Anwendergruppe Schweiz durfte OPENGIS.ch ihr Plugin um eine zusätzliche Funktionalität erweitern. Dieses Mal mit der Integration von WMTS als Datenquelle, eine ziemlich coole Sache. Doch was ist eigentlich der Unterschied zwischen WMS und WMTS?

      WMS vs. WMTS

      Zuerst zu den Gemeinsamkeiten: Beide Protokolle – WMS und WMTS – sind dazu geeignet, Kartenbilder von einem Server zu einem Client zu übertragen. Dabei werden Rasterdaten, also Pixel, übertragen. Ausserdem werden dabei gerenderte Bilder übertragen, also keine Rohdaten. Diese sind dadurch für die Präsentation geeignet, im Browser, im Desktop GIS oder für einen PDF Export.

      Der Unterschied liegt im T. Das T steht für “Tiled”, oder auf Deutsch “gekachelt”. Bei einem WMS (ohne Kachelung) können beliebige Bildausschnitte angefragt werden. Bei einem WMTS werden die Daten in einem genau vordefinierten Gitternetz — als Kacheln — ausgeliefert. 

      Der Hauptvorteil von WMTS liegt in dieser Standardisierung auf einem Gitternetz. Dadurch können diese Kacheln zwischengespeichert (also gecached) werden. Dies kann auf dem Server geschehen, der bereits alle Kacheln vorberechnen kann und bei einer Anfrage direkt eine Datei zurückschicken kann, ohne ein Bild neu berechnen zu müssen. Es erlaubt aber auch ein clientseitiges Caching, das heisst der Browser – oder im Fall von Swiss Locator QGIS – kann jede Kachel einfach wiederverwenden, ganz ohne den Server nochmals zu kontaktieren. Dadurch kann die Reaktionszeit enorm gesteigert werden und flott mit Applikationen gearbeitet werden.

      Warum also noch WMS verwenden?

      Auch das hat natürlich seine Vorteile. Der WMS kann optimierte Bilder ausliefern für genau eine Abfrage. Er kann Beispielsweise alle Beschriftungen optimal platzieren, so dass diese nicht am Kartenrand abgeschnitten sind, bei Kacheln mit den vielen Rändern ist das schwieriger. Ein WMS kann auch verschiedene abgefragte Layer mit Effekten kombinieren, Blending-Modi sind eine mächtige Möglichkeit, um visuell ansprechende Karten zu erzeugen. Weiter kann ein WMS auch in beliebigen Auflösungen arbeiten (DPI), was dazu führt, dass Schriften und Symbole auf jedem Display in einer angenehmen Grösse angezeigt werden, währenddem das Kartenbild selber scharf bleibt. Dasselbe gilt natürlich auch für einen PDF Export.

      Ein WMS hat zudem auch die Eigenschaft, dass im Normalfall kein Caching geschieht. Bei einer dahinterliegenden Datenbank wird immer der aktuelle Datenstand ausgeliefert. Das kann auch gewünscht sein, zum Beispiel soll nicht zufälligerweise noch der AV-Datensatz von gestern ausgeliefert werden.

      Dies bedingt jedoch immer, dass der Server das auch entsprechend umsetzt. Bei den von swisstopo via map.geo.admin.ch publizierten Karten ist die Schriftgrösse auch bei WMS fix ins Kartenbild integriert und kann nicht vom Server noch angepasst werden.

      Im Falle von QGIS Swiss Locator geht es oft darum, Hintergrundkarten zu laden, z.B. Orthofotos oder Landeskarten zur Orientierung. Daneben natürlich oft auch auch weitere Daten, von eher statischer Natur. In diesem Szenario kommen die Vorteile von WMTS bestmöglich zum tragen. Und deshalb möchten wir der QGIS Anwendergruppe Schweiz im Namen von allen Schweizer QGIS Anwender dafür danken, diese Umsetzung ermöglicht zu haben!

      Der QGIS Swiss Locator ist das schweizer Taschenmesser von QGIS. Fehlt dir ein Werkzeug, das du gerne integrieren würdest? Schreib uns einen Kommentar!

      Publié: 12 June 2023, 11:00am CEST

      Join this webinar to learn more about the new features in QGIS to process LiDAR data:

      Date: Monday, June 26, 2023 at 14:00 GMT

      Duration: 30 minutes + 15 minutes Q&A session

      Speaker: Martin Dobias, CTO at Lutra Consulting with more than 15 years of QGIS development experience

      Martin Dobias

      Description

      Point clouds are an increasingly popular data type thanks to the decreasing cost of their acquisition through lidar surveys and photogrammetry. On top of that, more and more national mapping agencies release high resolution point cloud data (spanning large areas and consisting of billions of points), unlocking many new use cases.

      This webinar will summarize the latest QGIS release 3.32 and the addition of tools for point cloud analysis right from QGIS Processing toolbox: clip, filter, merge, export to raster, extract boundaries and more - all backed by PDAL library that already ships with QGIS, without having to rely on third party proprietary software.

      This work was made possible by the generous donations to our crowdfunding.

    • sur Lutra consulting: Virtual Point Clouds (VPC)

      Publié: 8 June 2023, 4:00pm CEST

      As a part of our crowdfunding campaign we have introduced a new method to handle a large number of point cloud files. In this article, we delve into the technical details of the new format, rationale behind our choice and how you can create, view and process virtual point cloud files.

      Rationale

      Lidar surveys of larger areas are often multi-terabyte datasets with many billions of points. Having such large datasets represented as a single point cloud file is not practical due to the difficulties of storage, transfer, display and analysis. Point cloud data are therefore typically stored and distributed split into square tiles (e.g. 1km x 1km), each tile having a more manageable file size (e.g. ~200 MB when compressed).

      Tiling of data solves the problems with size of data, but it introduces issues when processing or viewing an area of interest that does not fit entirely into a single tile. Users need to develop workflows that take into account multiple tiles and special care needs to be taken to deal with data near edges of tiles to avoid unwanted artefacts in outputs. Similarly, when viewing point cloud data, it becomes cumbersome to load many individual files and apply the same symbology.

      Here is an example of several point cloud tiles loaded in QGIS. Each tile is styled based on min/max Z values of the tile, creating visible artefacts on tile edges. The styling has to be adjusted for each layer separately:

      An example of individual point cloud tiles loaded in QGIS, each styled differently

      Virtual Point Clouds

      In the GIS world, many users are familiar with the concept of virtual rasters. A virtual raster is a file that simply references other raster files with actual data. In this way, GIS software then treats the whole dataset comprising many files as a single raster layer, making the display and analysis of all the rasters listed in the virtual file much easier.

      Borrowing the concept of virtual rasters from GDAL, we have introduced a new file format that references other point cloud files - and we started to call it virtual point cloud (VPC). Software supporting virtual point clouds handles the whole tiled dataset as a single data source.

      At the core, a virtual point cloud file is a simple JSON file with .vpc extension, containing references to actual data files (e.g. LAS/LAZ or COPC files) and additional metadata extracted from the files. Even though it is possible to write VPC files by hand, it is strongly recommended to create them using an automated tool as described later in this post.

      On a more technical level, a virtual point cloud file is based on the increasingly popular STAC specification (the whole file is a STAC API ItemCollection). For more details, please refer to the VPC specification that also contains best practices and optional extensions (such as overviews).

      Virtual Point Clouds in QGIS

      We have added support for virtual point clouds in QGIS 3.32 (released in June 2023) thanks to the many organisations and individuals who contributed to our last year’s joint crowdfunding with North Road and Hobu. The support in QGIS consists of three parts:

      1. Create virtual point clouds from a list of individual files
      2. Load virtual point clouds as a single map layer
      3. Run processing algorithms using virtual point clouds

      Those who prefer using command line tools, PDAL wrench includes a build_vpc command to create virtual point clouds, and all the other PDAL wrench commands support virtual point clouds as the input.

      Using Virtual Point Clouds

      In this tutorial, we are going to generate a VPC using the new Processing algorithm, load it in QGIS and then generate a DTM from terrain class. You will need QGIS 3.32 or later for this. For the purpose of this example, we are using the LiDAR data provided by the IGN France data hub.

      In QGIS, open the Processing toolbox panel, search for the Build virtual point cloud (VPC) algorithm ((located in the Point cloud data management group):

      VPC in the Processing toolbox

      VPC algorithm in the Processing toolbox

      In the algorithm’s window, you can add point cloud layers already loaded in QGIS or alternatively point it to a folder containing your LAZ/LAS files. It is recommended to also check the optional parameters:

      • Calculate boundary polygons - QGIS will be able to show the exact boundaries of data (rather than just rectangular extent)

      • Calculate statistics - will help QGIS to understand ranges of values of various attributes

      • Build overview point cloud - will also generate a single “thinned” point cloud of all your input data (using only every 1000th point from original data). The overview point cloud will be created next to the VPC file - for example, for mydata.vpc, the overview point cloud would be named mydata-overview.copc.laz

      VPC algorithm inputs, outputs and options

      VPC algorithm inputs, outputs and options

      After you set the output file and start the process, you should end up with a single VPC file referencing all your data. If you leave the optional parameters unchecked, the VPC file will be built very quickly as the algorithm will only read metadata of input files. With any of the optional parameters set, the algorithm will read all points which can take some time.

      Now you can load the VPC file in QGIS as any other layer - using QGIS browser, Data sources dialog in QGIS or by doing drag&drop from a file browser. After loading a VPC in QGIS, the 2D canvas will show boundaries of individual files - and as you zoom in, the actual point cloud data will be shown. Here, a VPC loaded together with the overview point cloud:

      Zooming in QGIS in 2D map with elevation shading - initially showing just the overview point, later replaced by the actual dense point cloud:

      VPC algorithm output in 2D maps

      VPC output on 2D: displaying details when zooming in

      In addition to 2D maps, you can view the VPC in a 3D map windows too:

      If the input files for VPCs are not COPC files, QGIS will currently only show their boundaries in 2D and 3D views, but processing algorithms will work fine. It is however possible to use the Create COPC algorithm to batch convert LAS/LAZ files to COPC files, and then load VPC with COPC files.

      It is also worth noting that VPCs also work with input data that is not tiled - for example, in some cases the data are distributed as flightlines (with lots of overlaps between files). While this is handled fine by QGIS, for the best performance it is generally recommended to first tile such datasets (using the Tile algorithm) before doing further display and analysis.

      Processing Data with Virtual Point Clouds

      Now that we have the VPC generated, we can run other processing algorithms. For this example, we are going to convert the ground class of the point cloud to a digital terrain model (DTM) raster. In the QGIS Processing toolbox, search for Export to raster algorithm (in the Point cloud conversion group):

      VPC as an input to processing algorithms

      VPC layer can be used as an input to the point cloud processing algorithm

      This will use the Z values from the VPC layer and generate a terrain raster based on a user defined resolution. The algorithm will process the tiles in parallel, taking care of edge artefacts (at the edges, it will read data also from the neighbouring tiles). The output of this algorithm will look like this:

      Converting a VPC layer to a raster

      Converting a VPC layer to a DTM

      The output raster contains holes where there were no points classified as ground. If needed for your use case, you can fill the holes using Fill nodata algorithm from GDAL in the Processing toolbox and create a smooth terrain model for your input Virtual Point Cloud layer:

      Filling the holes in the DTM

      Filling the holes in the DTM

      Virtual point clouds can be used also for any other algorithms in the point cloud processing toolbox. For more information about the newly introduced algorithms, please see our previous blog post.

      All of the point cloud algorithms also allow setting filtering extent, so even with a very large VPC, it is possible to run algorithms directly on a small region of interest without having to create temporary point cloud files. Our recommendation is to have input data ready in COPC format, as this format provides more efficient access to data when spatial filtering is used.

      Streaming Data from Remote Sources with VPCs

      One of the very useful features of VPCs is that they work not only with local files, but they can also reference data hosted on remote HTTP servers. Paired with COPCs, point cloud data can be streamed to QGIS for viewing and/or processing - that means QGIS will only download small portions of data of a virtual point cloud, rather than having to download all data before they could be viewed or analysed.

      Using IGN’s lidar data provided as COPC files, we have built a small virtual point cloud ign-chambery.vpc referencing 16 km2 of data (nearly 700 million points). This VPC file can be loaded in QGIS and used for 2D/3D visualisation, elevation profiles and processing, with QGIS handling data requests to the server as necessary. Processing algorithms only take a couple of seconds if the selected area of interest is small (make sure to set the “Cropping extent” parameter of algorithms).

      All this greatly simplifies data access to point clouds:

      • Data producers can use very simple infrastructure - a server hosting static COPC files together with a single VPC file referencing those COPC files.

      • Users can use QGIS to view and process point cloud data as a single map layer, with no need to download large amounts of data, QGIS (and PDAL) taking care of streaming data as needed.

      We are very excited about the opportunities that virtual point clouds are bringing to users, especially when combined with COPC format and access from remote servers!

      Thanks again to all contributors to our crowdfunding campaign - without their generous support, this work would not have been possible.
