      Yesterday's election in Spain has resulted in no clear winner. Going into the election the opinion polls had suggested that the conservative People’s party (PP) would secure a comfortable win and would likely form a coalition government with the far-right Vox party. After all the votes were counted however PP had won only 136 seats to the ruling left-wing PSOE’s 122 seats. The far-right Vox

    • 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.
      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%

    • 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!

        • 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 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 is a Bellingcat reporter who uses open source tools to look at open source data to help confirm stories.

      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.

    • 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.

    • 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!

    • sur A recap of the 126th OGC Member Meeting, Huntsville, AL, USA

      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

      The always wonderful Executive Dinner was held on Wednesday night at the U.S. Space & Rocket Center – Davidson Center for Space Exploration, where attendees had the unforgettable experience of dining under an actual Saturn V rocket – one of only three in the world!

      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. 

      My well-deserved congratulations go out to both recipients!

      Ryan Ahola (R) accepts the inaugural OGC Community Impact Award, on behalf of Natural Resources Canada, from OGC CEO Dr. Nadine Alameh (L) Important Things and the Closing Plenary

      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.

      Thank you to our community

      The GEOHuntsville Member Meeting was not only one of our most attended, but also one of our most memorable – with the beautiful grounds and the unforgettable Saturn V Rocket. As always it was a pleasure seeing our Members interacting, collaborating, and driving technology and standards development forward. It’s the vibrancy and enthusiasm of our community that makes OGC truly special – and my job so enjoyable. So I thank you all, once again, for your time & energy and your dedication to making OGC the world’s leading and most comprehensive community of location experts.

      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.

      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.

Desde cualquier geoportal (de uso interno, claro) que tenga habilitada esta herramienta, una persona con permisos de acceso podrá consultar cualquier parcela – urbana o rústica – y acceder no solo a los datos públicos que proporciona la Sede Electrónica del Catastro sino también a los datos protegidos. Este tipo de consultas son necesarias y habituales en determinados procesos de gestión municipal, especialmente en algunos departamentos como Patrimonio.

      Los que nos vais siguiendo ya tendréis claro que los geoportales realizados con gvSIG Online tienden a infinito. Cada día surgen nuevos geoportales de las numerosas y crecientes organizaciones que lo tienen implementado. Una de las IDE (Infraestructuras de Datos Espaciales) de referencia donde se utiliza gvSIG Online es la de Uruguay. Aunque inicialmente se pensó para utilizarse para un único geoportal, el propio de la IDE que recopila la información básica del país, poco a poco se han ido generando más y más geoportales – unos públicos, otros muchos privados – para gestionar y divulgar información geográfica de todo tipo (catastral, estadística, sanitaria,… ).

      Hoy os compartimos uno de los geoportales públicos, en este caso de temática medioambiental, y que permite consultar la distribución de las especies exóticas invasoras en Uruguay. El geoportal cuenta con las principales herramientas ya disponibles en la IDE, algunas de interés para evaluar la distribución de estas especies como es el cálculo de perfiles longitudinales.

    • 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!

    • 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.

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 The 2023 OGC Tiling Interfaces Code Sprint – How it went!

      Publié: 23 June 2023, 3:08pm CEST par Simon Chester

      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.

      Figure 7 shows a map created by KORTxyz from the vector tiles distribution of the Ordnance Survey Zoomstack product and accessed through an OGC API – Tiles interface.

      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.

      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.

Pese a ser una administración local pequeña dispone de una gran cantidad y variedad de información geográfica que necesita gestionar.

      La implementación de una IDE con gvSIG Online les ha permitido cambiar una situación de partida con información no catalogada, no compartida, duplicada, con dificultad para actualizar… por un sistema interoperable, organizado, estandarizado que facilita tanto la gestión interno como aporta un nuevo mecanismo para transmitir la información a los ciudadanos y visitantes del municipio.

    • 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.

      The Open Geospatial Consortium (OGC) is pleased to announce that OGC CEO, Dr. Nadine Alameh, has received the 24th Annual Women in Technology Leadership Award in the Non-Profit and Academia category, which honors women who demonstrate exemplary leadership traits and have achieved success in a non-profit organization or educational institution.

      The Women in Technology’s Annual Leadership Awards seek to “recognize and honor female leaders whose achievements, mentorship and contributions to the community align with the WIT mission of advancing women in technology from the classroom to the boardroom” by honoring and celebrating female professionals who have found success in entrepreneurial, STEM, government, and corporate industries while inspiring colleagues, partners, and their community.

      “These awards are a cornerstone of the WIT mission to advance women in technology from the classroom to the boardroom,” said Amber Hart, President of WIT and the Co-Owner/Founder, The Pulse of GovCon, in a press release for the awards. “Recognizing the success of these women provides a vision for current and future leaders of what is possible with determination and focus and highlights the role of mentorship and sponsorship in building a successful and meaningful career.”

      In the nomination letter for the award, Chair of the OGC Board, Jeff Harris, Vice Chair, Prashant Shukle, and Board member, Zaffar Sadiq Mohamed-Ghouse, said that the OGC board nominated Nadine for her “outstanding global leadership of the Open Geospatial Consortium and its 500 members through a period of profound change. 

      “When Nadine assumed the role of Chief Executive Officer, she articulated a new vision and role for the OGC – one where it had to be relevant at the speed of change. To that end, she has worked tirelessly in pursuit of this vision as she mobilized some of the world’s largest technology companies, developed and developing national governments, and small- and medium-sized businesses and startups. That she delivered in a not-for-profit entity and with a steely resolve to ensure the global public interest – not only speaks of the scale of her achievements but also its impact on the global public good.”

      The 24th Annual Leadership Awards were presented at a Gala on Thursday, May 18, 2023, at the Hyatt Regency in Reston, VA, USA.

      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!

      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.

      The ShadeMap: Direct Sunlight Chart is an interactive map which can calculate the number of hours of direct sunlight for any location on Earth. Unlike traditional sun charts, this map actually accounts for shadows cast by buildings and terrain. If a tall building or mountain blocks out the sun for part of the day this is taken into account in the sunlight chart for that location. The
