    • sur Ian Turton's Blog: Adding a spell check to QGIS

      Posted: 16 July 2024, 2:00am CEST
      Adding a Spell Check to QGIS

      (Or what to do on a rainy bank holiday in Glasgow)

      This Monday was a local bank holiday in Glasgow (or at least the university) as a remnant of when the whole town took a train to Blackpool in the same two weeks so that the ship builders and steel works could stop in a coordinated fashion. As is required in the UK the weather was awful so I stayed in and being bored looked at my long list of possible projects. I picked one that has been kicking around on the list for a while adding a spell checker for QGIS. As a dyslexic I have spell checking turned on in nearly every program I enter text into including vim, InteliJ and my browser. So I have always felt that what QGIS really needed was a way to spell check maps before I printed them at A3 and put them on the wall.

      Back in 2019 North Road wrote a iblog post about custom layout checks and ended it with a throw away comment “It’d even be possible to hook into one of the available Python spell checking libraries to write a spelling check!”. I came across this when I was trying to see if there was an easy way for my students (many of whom have English as a second language) to avoid handing in projects with glaring (i.e. I can see them) spelling errors in the title. So I stuck the link on my backlog, until the proverbial rainy day came along.


      Obviously I’m the last person who should be allowed to write spell checking software, but the joy of open source is that for things like this someone else has almost certainly already done it. So a quick duck-duck-go found me installing pyspellcheck which seemed like it would do what I want. It has a pretty easy interface in that once you’ve created a spell checker object, you can just pass in a list of words and it will return a list of (probably) misspelled words and a method to give the most likely correction and another method to give you list of other possibilities. Armed with this I could create a method to find and check all the text elements of a print layout.

      def layout_check_spelling(context, feedback):
          layout = context.layout
          results = []
          checker = SpellChecker()
          for i in layout.items():
              if isinstance(i, QgsLayoutItemLabel):
                  text = i.currentText()
                  tokens = [word.strip(string.punctuation) for word in text.split()]
                  misspelled = checker.unknown(tokens)
                  for word in misspelled:
                      res = QgsValidityCheckResult()
                      res.type = QgsValidityCheckResult.Warning
                      res.title = 'Spelling Error?'
                      template = f"""
                      <strong>'{word}</strong>' may be misspelled, would
                      '<strong>{checker.correction(word)}</strong>' be a better choice?
                      possibles = checker.candidates(word)
                      if len(possibles) > 1:
                          template += """
                          Or one of:<br/>
                          for t in possibles:
                              template += f"<li>{t}</li>\n"
                          template += '</ul>'
                      res.detailedDescription = template
          return results

      And in theory, that was that! But I’m pretty sure that my students (and everyone else) probably didn’t want to cut and paste that into the console every time they wanted to spell check a map. So, I looked at how to package this up for QGIS. I built a plugin (using the plugin builder tool), but then things got a little tricky as I can’t see any way for a plugin to add itself to the print layout rather than the main QGIS window (please let me know if it is possible), and it seemed unintuitive to make people press a button in one window to effect another one, besides the whole point of being a QgsAbstractValidityCheck was that the method is automatically run on print. So I didn’t need most of the plugin code or did I? On further thought I did, there is a need for some GUI as the user can pick which language they want to use in the spell check. pyspellcheck can spell check English, Spanish, French, Portuguese, German, Italian, Russian, Arabic, Basque, Latvian and Dutch (so if those are your language then please test this for me). I also thought that providing the option to supply a different to the default personal dictionary might be useful. So that made use of the dialog that pops up when you hit the plugin.

      But it turns out you can’t register a class method as as a QgsAbstractValidityCheck since it gets confused when QGIS calls it later. So I had to move my checker method outside the plugin class. But then I couldn’t access the language and dictionary that was set in the GUI! Some more searching gave me the following code:

        _instance = plugins['qgis-spellcheck']
        checker = _instance.checker

      Whereby I can pull out the named plugin and grab it’s spell checker, which was created in the plugin’s __init__ method. I seem to have a small issue that the user’s profile is not set when that runs which messes up where the personal dictionary is put (again if you know how to fix this let me know).

      Future Work

      Ideally, I’d like the spell checker to scan and highlight the text in the boxes as I typed but I fear that is beyond my understanding of the QGIS/Qt interface. Next highest on my wish list is for the list of spelling issues to be non-modal so I can cut and paste fixes into the text box, rather than having to memorise the correct spelling, close the window and then type it in (again answers on a github issue).

      I’m sure all sorts of things will come up once people start using it, so as usual issues and PRs are welcome at [https:]

    • sur KAN T&IT Blog: IOT Solution Congress en Brasil, nuestra experiencia

      Posted: 12 July 2024, 7:35pm CEST

      El pasado mes de junio se llevó a cabo el IOT Solutions Congress en la ciudad de San Pablo, Brasil, donde más de 5.000 personas se reunieron para ver las soluciones más avanzadas en la industria del Internet de las Cosas (IOT).

      El Internet de las Cosas es un concepto tecnológico que se resume como una red de dispositivos interconectados, ya sea a través de internet u otro tipo de redes, con el fin de enviar y recibir información en tiempo real y de forma automatizada.

      Como muchas tecnologías innovadoras, el IOT tiene una amplia variedad de aplicaciones y usos, y esto se vió reflejado en la diversidad de las empresas que se acercaron al evento de San Pablo para conocer más sobre el tema. Se destacó la presencia de empresas de la industria petroquímica, minera, agrícola, de la construcción y organismos gubernamentales.

      En esta ocasión KAN participó del evento con un stand y con un espacio en el Startup Stage, donde Ariel Anthieni (CEO) dió una charla sobre las aplicaciones y beneficios de los Gemelos Digitales (Digital Twins) con un enfoque particular en el monitoreo de tránsito de las ciudades.

      Un Gemelo Digital es una réplica digital altamente precisa de objetos de todo tipo, desde vehículos y turbinas hasta ciudades enteras, cuyo fin es el de crear simulaciones que puedan optimizar el uso de dichos objetos. El mayor valor que otorga un Gemelo Digital es que utiliza datos reales para llevar a cabo estas simulaciones.

      Primero se recolectan los datos utilizando dispositivos de telemetría IOT (sensores térmicos, caudalímetros, acelerómetros, etc.), luego se procesa esta información y finalmente se vuelca sobre el modelo virtual. Utilizando este modelo se pueden realizar diferentes tipos de simulaciones, analizar cada uno de los distintos escenarios y buscar mejoras para optimizar los recursos que se disponen.

      Por ejemplo, utilizando sensores de vibración y un gemelo digital, se puede analizar el uso real de una bomba de agua, simular distintos escenarios y establecer cuándo debe hacerse el mantenimiento preventivo óptimo según los datos obtenidos.

      Para el caso de las ciudades, Ariel explicó en su charla que los Gemelos Digitales permiten ayudar a los organismos gubernamentales a ver de forma anticipada el impacto que determinadas políticas públicas pueden tener en la organización de la ciudad.

      Ariel lo explica en dos ejemplos sencillos: Conociendo el movimiento real de los colectivos en las ciudades, se puede simular el impacto que tendrán en sus recorridos si una avenida principal es clausurada completamente. Esto permite al gobierno buscar la reorganización óptima y desplegar eficazmente a los equipos de tránsito que llevarán a cabo la tarea.

      Otro ejemplo se ve en la ciudad de Japón, donde el gobierno utiliza Gemelos Digitales para realizar simulaciones de terremotos y tsunamis para mejorar su capacidad de respuesta y recuperación ante los desastres naturales.

      En conclusión, KAN cumplió con su cometido en el congreso de IOT logrando mostrar una solución vanguardista dentro de la industria IOT y dejando en claro que es una de las startups a seguir.

    • sur gvSIG Team: Acceptance Speech for the National Geographic Science Award

      Posted: 12 July 2024, 8:17am CEST

      Honorable Mr. Jesús Gómez, Undersecretary of Transport and Sustainable Mobility, distinguished authorities, ladies and gentlemen,

      It is an immense honor and a profound satisfaction for me to receive, on behalf of the gvSIG Association, the first National Geographic Science Award ever given in Spain. We humbly confess that being the first to receive it, with so many deserving individuals and entities, further elevates the importance we place on this award. Additionally, it ensures that you will hear the best acceptance speech for the award to date.

      This award represents an extraordinary recognition of the trajectory and dedication of a group passionate about geography, technology, and knowledge, understood as drivers of change.

      Let us begin with the term that names this award, geography. Tim Marshall, in his excellent essay “Prisoners of Geography,” concluded that while geography does not dictate the development of all events, since great ideas and leaders are part of the push and pull of history, all must act within the confines that geography sets. Former U.S. President Barack Obama told us that geography was much more than putting names on a map; it was about understanding reality. Those who have listened to us over the years well know that in the gvSIG Association, we have always affirmed that reality manifests in the territory. Everything exists to the extent that it is in a place and how it relates to what is around it. Therefore, the geographic or spatial dimension of things is a fundamental attribute for managing reality. It was in the past, it will be in the future, and undoubtedly, it is in the present.

      This leads us to talk about the second concept that excites us, technology. With more than two decades into the 21st century, we must all be aware that technology permeates every productive, economic, academic, and social process to the point of becoming an indispensable tool. Without fear of being wrong, I could say that there are more technological devices in this room than people. We cannot imagine that management of reality we spoke of without technology. We know that Spain and the European Union are significantly betting on science, technology, and innovation as fundamental pillars for their growth and sustainable development. For our part, in the gvSIG Association, we have always talked about technology as a strategic sector and will continue to insist on it as long as necessary. Geographic information management technologies, encompassed under the concept of geomatics, are those that allow us to analyze, understand, and manage the territory, geography.

      Geomatics is applied in managing infrastructures of all kinds, in sectors such as the environment, security, energy, mobility, education, health, agriculture, tourism,… it is transversal to countless themes and applicable to countless geographies.

      Thus, we should begin to be aware that being dependent on a strategic sector is a manifest weakness. Who would want our administrations, our universities, our companies, those that work in and with the territory, to be technologically dependent? Herein lies much of the importance and success of the gvSIG project: building and developing technologies for managing spatial data, its geographic dimension, with free software. Betting on technological sovereignty by promoting solutions that grant all rights and freedoms to their users. That avoid any dependence not only on technologies but on the owners of these. Not only that, the gvSIG Association has fostered its own industrial fabric, specialized in geomatics, making the Valencian Community and Spain a reference center internationally. Today, not only are gvSIG-branded technologies used worldwide, but today, Spanish companies carry out some of the largest projects related to geographic information systems around the globe. I conclude this section by reaffirming that betting on our own and free technologies can be, undoubtedly is, a strategic decision of the highest order.

      We link this to the last concept related to the gvSIG Association’s activity, knowledge. And at this point, it might be worthwhile to take a look back at the history of our entity.

      Let us not forget that if we are here today, receiving this important recognition, it is because one day a public administration, the Generalitat Valenciana, decided to take the first step. The gvSIG project came to light in 2004, with a first version of a software product that today is part of a complete catalog of geomatics solutions. Today, not only is it talked about, but legislation in Spain and Europe promotes reuse, sharing, interoperability among administrations, and the development of our own technologies. At the beginning of this century, it was not so. The Generalitat Valenciana not only took the first step but knew how to share the achievements with the entire international community and energize what would end up being the gvSIG Association.

      Today, it continues to bet on the project, using gvSIG technologies in more and more areas, from agriculture to road safety, from industry to sustainable mobility, contributing to its development and also reusing all the technological improvements that are continuously consolidated in the project. Just last week, the Danish Agency for Digital Government published a report highlighting the Generalitat Valenciana as the main success case for the promotion of free software technology by a public administration. It spoke of gvSIG.

      Therefore, this award, this recognition, is largely shared with the Generalitat Valenciana and, in particular, with its Directorate General of Information and Communication Technologies.

      At the end of 2009, the gvSIG Association was born. A group of people, companies, and entities decided to scale the impact of the project. To ensure its sustainability on the one hand, to consolidate an incipient industrial fabric on the other. The premise might seem simple, but it was not easy to implement. Bringing the values of free software to the economy. Developing a new business model – a concept much talked about – based on collaboration, shared knowledge versus speculation with acquired knowledge, solidarity versus rivalry. From the dates, you may guess that we were born in the midst of a crisis, in difficult times, with few resources but with great enthusiasm. In those early years, we made the English proverb “A smooth sea never made a skilled sailor” our own. It was necessary to dream, and believing in our dreams has brought us here. After this time, we do not forget to keep dreaming.

      Today, in 2024, the gvSIG Association is an entity recognized worldwide. The technology derived from a project born, let us not forget, on the periphery of Europe is used in more than 160 countries. We participate and collaborate with the main forums and organizations that promote Geographic Sciences, open knowledge, and interoperability. We have received international awards from entities such as NASA or the European Commission, which last year recognized gvSIG as the most important free software project in Europe. We have developed a suite or catalog of free technologies that allow addressing any need for information management with a geographic dimension, for any organization. We collaborate on R+D+I projects with dozens of universities, scientific publications citing the use of gvSIG are multiplying. gvSIG’s social networks have a notable influence with thousands of followers. And regarding that new business model we talked about… we have promoted the consolidation of Spanish companies and developed projects in more than 30 countries for entities of all kinds, from the United Nations to small municipalities, from large private sector energy companies to NGOs. We are, in short, an international reference center.

      Our history, therefore, pivots around knowledge. Developing it to share it, to reduce asymmetries between territories, to generate quality economy, to reaffirm Antonio Machado’s saying that “in matters of culture and knowledge, you only lose what you keep; you only gain what you give.”

      I want to recall an anecdote that well reflects this phrase. An example of those other values, not quantifiable, that occur around the model of knowledge, development, and business we promote in the gvSIG Association.

      At an event organized by Itaipú Binacional in Foz do Iguaçu, Brazil, we were invited to give training courses both to the staff of the hydroelectric plant and, openly, to university students who wanted to attend. In the first training course, a male and a female student sitting in the front row asked the trainer (in this case, it was me) if he could put them in touch with the event organizers to ask for affordable accommodation. Then they told me their story…

      At the University of Asunción, Paraguay, where they were studying, the students collectively requested the faculty to give them training in gvSIG, as they considered it a strategic investment for the country to have engineers trained in free software technologies, with all the advantages that entails. The faculty, familiar only with non-free products, refused. Among all the students, it was decided to collect funds to allow one male and one female student to make the long journey to Foz do Iguaçu, receive training, and thus, upon returning, be able to replicate the training for all the students. Today, several of those students hold responsible positions in the country.

      If we have come this far, it is because many people think there can be other approaches, other ways of doing things. Therefore, to conclude, I want to thank all the people who were, are, or will be in the gvSIG project: workers, entities, communities… and especially to the colleagues for their effort and commitment, who have always put themselves at the service of the project and never put the project at their service. Our future will be full of maps, standards, algorithms, and lines of code, but above all, of people working towards a common goal. Thank you very much.

      We would like this opportunity to highlight two plugins, Viper (QGIS snake Clone) and Active Break.

      Viper allows to emulate in QGIS canvas the popular game Snake, providing a fun time and a bit of nostalgia for the “older” users. However it goes further than that, as it serves the purpose of teaching about geospatial concepts such as geometry objects (points, polygons) with their properties and methods, spatial indexing in the form of R-Tree, but also programming in QGIS, as well as other aspects.

      On a more serious tone, if it can be said that, we present Active Break, a plugin that “simply” presents messages at specific time intervals, which can be personalized by the user and range from the more technical such as “save your project”, personal or motivational like quotes from hundreds of people on multiple subjects, or perhaps the most important, routinely reminders to take a break, relax or go have lunch. This considering the long hours we spent daily in front of the computer, with all the physical and mental health, as well as social implications. Congratulations on both authors!

    • sur Free and Open Source GIS Ramblings: New MovingPandas tutorial: taking OGC Moving Features full circle with MF-JSON

      Posted: 8 July 2024, 8:00am CEST

      Last week, I had the pleasure to meet some of the people behind the OGC Moving Features Standard Working group at the IEEE Mobile Data Management Conference (MDM2024). While chatting about the Moving Features (MF) support in MovingPandas, I realized that, after the MF-JSON update & tutorial with official sample post, we never published a complete tutorial on working with MF-JSON encoded data in MovingPandas.

      The current MovingPandas development version (to be release as version 0.19) supports:

      • Reading MF-JSON MovingPoint (single trajectory features and trajectory collections)
      • Reading MF-JSON Trajectory
      • Writing MovingPandas Trajectories and TrajectoryCollections to MF-JSON MovingPoint

      This means that we can now go full circle: reading — writing — reading.

      Reading MF-JSON

      Both MF-JSON MovingPoint encoding and Trajectory encoding can be read using the MovingPandas function read_mf_json(). The complete Jupyter notebook for this tutorial is available in the project repo.

      Here we read one of the official MF-JSON MovingPoint sample files:

      traj = mpd.read_mf_json('data/movingfeatures.json')
      Writing MF-JSON

      To write MF-JSON, the Trajectory and TrajectoryCollection classes provide a to_mf_json() function:

      The resulting Python dictionary in MF-JSON MovingPoint encoding can then be saved to a JSON file, and then read again:

      import json
      with open('mf1.json', 'w') as json_file:
          json.dump(mf_json, json_file, indent=4)

      Similarly, we can read any arbitrary trajectory data set and save it to MF-JSON.

      For example, here we use our usual Geolife sample:

      gdf = gp.read_file('data/demodata_geolife.gpkg')
      tc = mpd.TrajectoryCollection(gdf, 'trajectory_id', t='t')
      mf_json = tc.to_mf_json(temporal_columns=['sequence'])
      And reading again
      import json
      with open('mf5.json', 'w') as json_file:
          json.dump(mf_json, json_file, indent=4)
      tc = mpd.read_mf_json('mf5.json', traj_id_property='trajectory_id' )

      The implemented MF-JSON support covers the basic usage of the encodings. There are some fine details in the standard, such as the distinction of time-varying attribute with linear versus step-wise interpolation, which MovingPandas currently does not support.

      If you are working with movement data, I would appreciate if you can give the improved MF-JSON support a spin and report back with your experiences.

    • sur Mappery: Nikko on a Shopping Bag

      Posted: 7 July 2024, 11:00am CEST

      Maarten Pullen sent me this picture of a shopping bag with a map of Nikko, Japan.

      “Yesterday I stumbled upon a plastic bag from Nikko, Japan, with several tourist spots on it.  I wrote a little blog post (in Dutch, but can be translated) about the background of the map


      Here is a rough translation of the first part of Maarten’s blog post:

      “For some time now I have been following Maps in the Wild, a collective that collects maps for aesthetic purposes in the broadest form. The core idea is that printed maps have less functional use thanks to digitization and are therefore used more for aesthetic reasons.

      Or it’s just an excuse to collect a lot of eye-catching cards, which is also a good idea in my opinion.

      A plastic bag from Japan came from the attic. And suddenly I realized that you can also translate it. And it also turned out to have a schematic map, showing, among other things, a bridge, temples, a ski resort and a waterfall (or Onsen?).

      I got the bag in 2010 in Nikko, Japan”

      And that is a perfect Map in the Wild! Thanks Maarten

      This 3D map of Jerusalem in the 19th century is massive and spectacular. It was brilliantly lit to take you through a day in the life of the city from the sun rising in the east through the day to sunset.

      “Stefan Illés, an Austro-Hungarian Catholic, arrived in Jerusalem in 1864 and worked as a bookbinder at the Franciscan publishing house. Illés built a model of Jerusalem that was exhibited in the Ottoman Pavilion at the World Expo in Vienna in 1873. The model, which was highly acclaimed, was displayed throughout Germany and Switzerland. In 1878, it was purchased by a distinguished family from Geneva. Illés’s impressive model is cartographically accurate and is considered a reliable scientific source for the history and geography of Jerusalem in the 19th century.”

      And that finishes my maps in the wild selection from King David’s Tower. There were loads more maps showing the evolution of the city through the different eras of history from the Egyptian period through Assyrian, Babylonian, Persian, Islamic, Crusader and Ottoman eras to the modern day. Well worth a visit.

Durante los días 17 al 22 de marzo, Ariel tuvo el privilegio de representar a nuestra empresa en este evento único que reunió a destacados actores en el ámbito de las ciudades inteligentes en la hermosa ciudad de Curitiba, Brasil.

      Curitiba es reconocida a nivel mundial como un ejemplo de ciudad inteligente debido a sus innovadoras políticas urbanas que han transformado la calidad de vida de sus habitantes. Su eficiente sistema de transporte público, sus áreas verdes bien planificadas y su enfoque en la sostenibilidad la convierten en un modelo a seguir para otras ciudades.

      Durante el evento, Ariel tuvo el honor de cruzar unas palabras con Rafael Greca, el alcalde de Curitiba. Se sorprendió gratamente por su calidez e increíble predisposición para conversar y conocer a quienes estábamos allí.

      Nuestro CEO participó activamente en las diferentes actividades de la feria, incluyendo la asistencia a charlas y conferencias con reconocidos expertos en el campo de la innovación urbana, la visita a espacios temáticos y la exploración de soluciones tecnológicas innovadoras para el desarrollo sostenible de las ciudades. Tuvo la oportunidad de presentar al MapViewer, un visor digital diseñado por Kan Territory & IT para la supervisión y gestión virtual de las ciudades. Este permite monitorear y controlar diferentes aspectos de ese lugar, como el flujo del transporte público, la actividad de los centros de salud y otros servicios esenciales, a través de la recopilación y visualización de datos geoespaciales.

      Ariel también destacó que el MapViewer utiliza un enfoque de catastro multifiduciario, capaz de manejar información de múltiples fuentes y tipos, como datos catastrales, topográficos y de infraestructura, proporcionando así una vista integral de la ciudad. Además, habló sobre la evolución digital de esta tecnología, introduciendo el concepto de «gemelos digitales«, que son representaciones virtuales de una ciudad. Con esta herramienta, los administradores y planificadores urbanos pueden simular escenarios hipotéticos y tomar decisiones más informadas para el desarrollo sostenible.

      Sin dudas, su actividad en Expocuritiba 2024 fue una oportunidad invaluable para conocer las últimas tendencias en tecnología urbana, establecer contactos estratégicos y compartir conocimientos con otros líderes en el ámbito de las ciudades inteligentes.

      Felicitamos a Ariel por su destacada participación en este evento tan significativo y esperamos seguir contribuyendo al desarrollo de ciudades más inteligentes y sostenibles en el futuro. Muchísimas gracias Lucía Bellocchio por haberlo hecho posible ¡Hasta el próximo año!

    • sur Free and Open Source GIS Ramblings: New interactive trajectory plots for MovingPandas & experiments on their interpretation using ChatGPT 4o

      Posted: 30 June 2024, 2:52pm CEST

      With the release of GeoPandas 1.0 this month, we’ve been finally able to close a long-standing issue in MovingPandas by adding support for the explore function which provides interactive maps using Folium and Leaflet.

      Explore() will be available in the upcoming MovingPandas 0.19 release if your Python environment includes GeoPandas >= 1.0 and Folium. Of course, if you are curious, you can already test this new functionality using the current development version.

      This enables users to access interactive trajectory plots even in environments where it is not possible to install geoviews / hvplot (the previously only option for interactive plots in MovingPandas).

      I really like the legend for the speed color gradient, but unfortunately, the legend labels are not readable on the dark background map since they lack the semi-transparent white background that has been applied to the scale bar and credits label.

      Speaking of reading / interpreting the plots …

      You’ve probably seen the claims that AI will help make tools more accessible. Clearly AI can interpret and describe photos, but can it also interpret MovingPandas plots?

      ChatGPT 4o interpretations of MovingPandas plots

      Not bad.

      And what happens if we ask it to interpret the animated GIF from the beginning of the blog post?

      So it looks like ChatGPT extracts 12 frames and analyzes them to answer our question:

      Its guesses are not completely off but it made up the facts such as that the view shows “how traffic speeds vary over time”.

      The problem remains that models such as ChatGPT rather make up interpretations than concede when they do not have enough information to make a reliable statement.

    • sur Mappery: King David’s Tower 1 – Adrichem’s Map

      Posted: 30 June 2024, 11:00am CEST

      While we were in Israel we spent some time in Jerusalem, friends suggested that we visit the new museum about Jerusalem in King David’s Tower. It is a fantastic museum in an ancient location which reflects the different influences in the city over three millenia. Amongst the many exhibits were a lot of maps, ancient, modern, interactive, over the next few days I will share a few.

      Adrichem was a 16th century Dutch cartographer, this map of Jerusalem shows remarkable detail

      “A map of Jerusalem created by the Dutch cartographer Christiaan van Adrichem in 1584. In this beautifully illustrated map are drawings that represent events and figures from the Old and New Testaments. Toward the center of the map the Jewish Temple can be seen together with a drawing of the High Priest, the altar and the vessels used in the Temple. To the right of the Temple is the Royal Palace, pictures of King Solomon on his throne, and even Bathsheva bathing on her rooftop. Other drawings on the map, such as the Via Delarosa and images of the Crucifixion, depict the Christian history of Jerusalem.”

    • sur gvSIG Team: Discurso de aceptación del Premio Nacional de Ciencias Geográficas

      Posted: 28 June 2024, 4:13pm CEST

      Excmo. Sr. Jesús Gómez, Subsecretario de Transportes y Movilidad Sostenible, distinguidas autoridades, señoras y señores

      Es para mi un inmenso honor y una profunda satisfacción recibir, en nombre de la Asociación gvSIG, el primer Premio Nacional de Ciencia Geográficas que se otorga en España. Humildemente confesamos que ser los primeros en recibirlo, con la cantidad de personalidades y entidades que lo merecen, todavía acrecienta más la importancia que le damos a este galardón. Por otro lado, nos asegura que escucharan el mejor discurso de aceptación del premio de los habidos hasta la fecha.

      Este galardón supone un reconocimiento extraordinario a la trayectoria y dedicación de un colectivo apasionado por la geografía, la tecnología y el conocimiento, entendidos como motores de cambio.

      Empecemos por el término que da nombre a este galardón, la geografía. Tim Marshall, en su excelente ensayo «Prisioneros de la Geografía» concluía que si bien la geografía no dicta el desarrollo de todos los acontecimientos, puesto que las grandes ideas y líderes forman parte del tira y afloja de la historia, todos ellos deben actuar dentro de los confines que marca la geografía. El ex-presidente de los Estados Unidos, Barack Obama, nos decía que la geografía era mucho más que poner nombres en un mapa, que se trataba de entender la realidad. Los que nos han escuchado durante estos años bien saben que en la Asociación gvSIG siempre hemos afirmado que la realidad se manifiesta en el territorio. Todo existe en la medida que está en un lugar y en cómo se relaciona con lo que tiene alrededor. Por tanto, la dimensión geográfica o espacial de las cosas es un atributo fundamental para gestionar la realidad. Lo fue en el pasado, lo será en el futuro y, sin duda, lo es en el presente.

      Lo que nos lleva a hablar del segundo concepto que nos apasiona, la tecnología. Con más de dos décadas en el S.XXI todos debemos ser conscientes que la tecnología impregna todo proceso productivo, económico, académico y social hasta el punto de convertirse en una herramienta imprescindible. Sin miedo a equivocarme podría afirmar que en esta sala hay más aparatos tecnológicos que personas. No podemos imaginar esa gestión de la realidad de la que hablábamos sin tecnología. Sabemos que España y la Unión Europea están apostando significativamente por la ciencia, la tecnología y la innovación como pilares fundamentales para su crecimiento y desarrollo sostenible. Por nuestra parte, en la Asociación gvSIG, siempre hemos hablado de la tecnología como un sector estratégico y seguiremos insistiendo mientras sea necesario. Las tecnologías de gestión de información geográfica, englobadas bajo el concepto de geomática, son aquellas que ni más ni menos nos permiten analizar, entender y gestionar el territorio, la geografía.

      La geomática se aplica en la gestión de infraestructuras de todo tipo, en sectores como el del medio ambiente, la seguridad, la energía, la movilidad, la educación, la sanidad, la agricultura, el turismo,… es transversal a infinidad de temáticas y aplicable a infinidad de geografías.

      Siendo así, deberíamos empezar a ser conscientes de que ser dependientes de un sector estratégico es una debilidad manifiesta. ¿Quién querría que nuestras administraciones, nuestras universidades, nuestras empresas, aquellas que trabajan en y con el territorio, fueran dependientes tecnológicamente? Aquí radica en gran parte la importancia y éxito del proyecto gvSIG, construir y desarrollar tecnologías para gestión de datos espaciales, de su dimensión geográfica, con software libre. Apostando por la soberanía tecnológica mediante el impulso de soluciones que otorgan todos los derechos y libertades a sus usuarios. Que evitan cualquier dependencia ya no de tecnologías, sino de los dueños de estas. No solo eso, la Asociación gvSIG ha impulsado un tejido industrial propio, especializado en geomática, convirtiendo a la Comunidad Valenciana y a España en un centro de referencia a nivel internacional. Hoy día no solo las tecnologías marca gvSIG se utilizan en todo el mundo, hoy día empresas españolas llevan a cabo por todo el planeta algunos de los más grandes proyectos relacionados con los sistemas de información geográfica. Concluyo este apartado reafirmando que apostar por tecnologías propias y libres puede ser, sin duda lo es, una decisión estratégica de primer orden.

      Enlazamos con el último concepto que relacionaba con la actividad de la Asociación gvSIG, el conocimiento. Y en este punto quizá valga la pena hacer un recorrido por la historia de nuestra entidad.

      No hay que olvidar que si hoy estamos aquí, recogiendo este importantísimo reconocimiento, es porque un día una administración pública, la Generalitat Valenciana, decidió dar el primer paso. El proyecto gvSIG ve la luz en 2004, con una primera versión de un producto de software que hoy forma parte de un completo catálogo de soluciones de geomática. Hoy no solo se habla, sino que se legisla, en España y en Europa, a favor de la reutilización, de compartir, de interoperar entre administraciones y de desarrollar tecnologías propias. En los comienzos de este siglo no era así. La Generalitat Valenciana no solo dio el primer paso, sino que supo compartir los logros con toda la comunidad internacional y dinamizar lo que acabaría siendo la Asociación gvSIG.

      Hoy día sigue apostando por el proyecto, utiliza las tecnologías gvSIG en cada vez más áreas, desde agricultura a seguridad vial, desde industria a movilidad sostenible, contribuyendo a su desarrollo y, también, reutilizando todas las mejoras tecnológicas que continuamente se consolidan en el proyecto. Sin ir más lejos, la semana pasada La Agencia de tecnologías del gobierno danés publicó un informe en que ponía como principal caso de éxito del impulso de una tecnología en software libre por una administración pública a la Generalitat Valenciana. Hablaba de gvSIG.

      Por tanto, este premio, este galardón, es en gran medida compartido con la Generalitat Valenciana y, en particular, con su Dirección General de Tecnologías de la Información y Comunicación.

      A finales de 2009 nació la Asociación gvSIG. Un conjunto de personas, empresas, entidades decidimos escalar el impacto del proyecto. Para garantizar sus sostenibilidad por un lado, para consolidar un tejido industrial incipiente por otro. La premisa puede parecer sencilla, pero no era fácil de implementar. Llevar los valores del software libre a la economía. Desarrollar un nuevo modelo de negocio – un concepto del que tanto se habla – basado en la colaboración, en el conocimiento compartido frente a la especulación con el conocimiento adquirido, en la solidaridad frente a la rivalidad. Por las fechas ya intuirán que nacimos en plena crisis, en momentos complicados, con escasos recursos pero con mucha ilusión. Esos primeros años hicimos nuestro el proverbio inglés de «que ningún mar en calma hizo experto a un marinero». Era preciso soñar y creyendo en nuestros sueños hemos llegado hasta aquí. Pasado este tiempo, no nos olvidamos de seguir soñando.

      Hoy, en 2024, la Asociación gvSIG es una entidad reconocida en todo el mundo. La tecnología derivada de un proyecto nacido, no lo olvidemos, en la periferia de Europa se utiliza en más de 160 países. Participamos y colaboramos con los principales foros y organizaciones que promueven las Ciencias Geográficas, el conocimiento abierto y la interoperabilidad. Hemos recibido premios internacionales de entidades como la NASA o la Comisión Europea, que el pasado año reconoció a gvSIG como el proyecto de software libre más importante de Europa. Hemos desarrollado una suite o catálogo de tecnologías libres que permiten abordar cualquier necesidad de gestión de información con dimensión geográfica, para cualquier organización. Colaboramos en proyectos de I+D+i con decenas de universidades, se multiplican las publicaciones científicas que citan el uso de gvSIG. Las redes sociales de gvSIG tienen una influencia notable con miles de seguidores. Y en relación a ese nuevo modelo de negocio del que hablábamos… hemos impulsado la consolidación de empresas españolas y desarrollado proyectos en más de 30 países para entidades de todo tipo, de Naciones Unidas a pequeños ayuntamientos, de grandes empresas privadas del sector de la energía a ONGDs. Somos, en definitiva, un centro de referencia a nivel internacional.

      Nuestra historia por tanto pivota alrededor del conocimiento. Desarrollarlo para compartirlo, para reducir asimetrías entre territorios, para generar economía de calidad, para reafirmar a Antonio Machado cuando decía que «en cuestiones de cultura y saber, solo se pierde lo que se guarda; solo se gana lo que se da».

      Quiero recordar una anécdota que refleja bien esta frase. Un ejemplo de esos otros valores, no cuantificables, que ocurren alrededor del modelo de conocimiento, desarrollo y negocio que impulsamos en la Asociación gvSIG.

      En un evento organizado por Itaipú Binacional en Foz do Iguaçu, en Brasil, se nos invitó a dar cursos de formación tanto al personal de la central hidroeléctrica como, de manera abierta, a aquellos universitarios que quisieran asistir. En el primer curso de formación, un alumno y una alumna que se situaban en primera fila, preguntaron al formador (en este caso, era yo) si podía ponerles en contacto con los organizadores del evento para preguntar por un hospedaje económico. Entonces me contaron su historia…

      En la Universidad de Asunción, Paraguay, donde ellos cursaban estudios, los alumnos en su conjunto habían solicitado al profesorado que les dieran formación en gvSIG, ya que consideraban que era una apuesta de futuro para el país el contar con ingenieros formados en tecnologías de software libre, con las ventajas que ello tiene. El profesorado, conocedor solo de productos no libres, se negó. Entre todos los estudiantes se decidió hacer una colecta que permitiera a uno y a una de ellos hacer el largo viaje a Foz do Iguaçu, formarse y así, al regresar, poder replicar la formación para todo el alumnado. Hoy día varios de esos alumnos tienen puestos de responsabilidad en el país.

      Si hemos llegado hasta aquí es porque hay mucha gente que piensa que puede haber otros enfoques, otras maneras de hacer las cosas. Por eso, para acabar quiero agradecer a todas las personas que estuvieron, están o estarán en el proyecto gvSIG, trabajadores, entidades, comunidades… y muy especialmente a los compañeros y compañeras por su esfuerzo y compromiso, siempre se han puesto al servicio del proyecto y nunca han puesto el proyecto a su servicio. Nuestro futuro estará llenos de mapas, estándares, algoritmos y líneas de código, pero sobre todo de personas trabajando por un objetivo común. Muchas gracias.

    • sur GIScussions: W3W – It’sGetting.Better.AlltheTime

      Posted: 28 June 2024, 2:36pm CEST

      Excuse the corny title and associated video but I couldn’t resist it.

      What3Words’s accounts for 2023 have just been published and the cynics who have doubted W3W’s commercial model were confounded by the outstanding progress that the company has made in 2023. Here are a few highlights to save you reading through 45 pages.

      • Revenues surged by 28% to break through the £1m barrier for the first time
      • Employee numbers fell from 152 to 128
      • Admin expenses fell by 54% to £21.7m – “primarily driven by the reduction in consumer acquisition activities and the fair value adjustment relating to convertible loan notes” (That’s less advertising and what might be described as “debt swap magic”)
      • The loss for the year fell by 48% to £16.4m
      • The Directors consider W3W to be a going concern with cash and cash equivalents of £14.8 and term deposits of £12.8 at the end of the year which gives them well over a year’s runway at current revenue and expenditure levels.
      • Raised £6.9m via a cash convertible loan instrument – it’s good to see that smart investors with a long term horizon continue to support W3W
      • W3W has cumulative losses of £136m so when they do start to make profits in the near future the tax authorities will not be a beneficiary for several years.

      You might think that summary was a bit dry so I asked a friendly AI to give me a slightly more positive view:

      What3Words absolutely smashed it in 2023!

      Revenue rockets! They blasted past the £1 million mark for the first time, a whopping 28% increase. That’s impressive growth for any company, but for a young innovator like What3Words, it’s a sign of things to come!

      Leaner, meaner, revenue machine! While the team size trimmed down slightly, they achieved amazing things. Admin expenses plummeted by 54%! This financial wizardry involved cutting back on marketing spend and some clever financial maneuvering. Talk about efficiency!

      Losses slashed in half! The deficit shrunk by a mighty 48%, proving their business model is tightening its grip.

      The future’s bright! With over £27 million in the bank and a year’s worth of runway at current spending, What3Words is well-positioned for continued success.

      Smart money says “Yes!” Investors are clearly bullish! A cool £6.9 million was raised through a fancy loan thingy (cash convertible loan instrument, for those keeping score). This shows that big thinkers recognize the long-term potential of What3Words.

      Taxman blues? Not anymore! With a hefty pile of past losses, What3Words gets a tax break for years to come. That’s more money to fuel their innovative ideas!

      In short, 2023 was a phenomenal year for What3Words. They’re growing, they’re efficient, and they’ve got the financial backing to keep pushing boundaries. If you’re looking for a company on the rise, What3Words is a shining star!

    • sur A recap of the 129th OGC Member Meeting, Montreal, Canada

      Posted: 27 June 2024, 2:00pm CEST by Simon Chester

      The 129th OGC Member Meeting was held in Montreal, Canada, from June 17-21, 2024. The meeting was hosted by OGC Strategic Member Natural Resources Canada, with additional support from Esri Canada, CAE, Safe Software, and Bentley Systems. The week saw more than 200 leaders and experts from industry, academia, and government come together—with a further 100 online—to learn about the latest innovations from OGC Members, advance Standards, network, and shape the future of geospatial technology. The meeting was also notable as it marked the beginning of OGC’s 30 year anniversary celebrations, which will culminate at an event in Washington, D.C., this December.

      Under the theme “Standards enabling collaboration for global challenges” the 129th Member Meeting focused on discussing, aligning, supporting, and promoting geospatial solutions that address challenges as far reaching as climate change and related disasters, and application domains as diverse as marine, Artificial Intelligence/Machine Learning (AI/ML), and beyond.

      Alongside the many OGC Standards and Domain Working Group meetings, there also included a Methane Summit, a Sensor Summit, a two-day meeting of the Canada Forum, a Quantum Computing ad hoc, a Metadata Workshop, and the kickoff of Testbed-20. 

      Friday’s OGC Executive Planning Committee Meeting was hosted by CAE at their nearby factory, and included a memorable tour of their factory floor. Social occasions included a Monday evening reception and a Wednesday night dinner was held at Northern Italian restaurant, Le Richmond. During the dinner, Andreas Matheus from Secure Dimensions GmbH was presented the 2024 Gardels Award for his persistent efforts to ensure best practices in security and API design in OGC. Congratulations, Andreas!

      Andreas Matheus (L) is presented the 2024 Gardels Award by OGC Chief Standards Officer, Scott Simmons (R).

      In addition to the challenges and domains covered by the meeting theme, two additional areas of discussion that stood out during the week: Digital Twins & Sensors, and Ethics in Geospatial.

      Digital Twins & Sensors. OGC members are increasingly demonstrating the use of digital twins of the built environment (e.g., city and building models) as the context and framework in which sensors are managed. Sensed information in the real world can be displayed on digital representations of that digital reality to enable better understanding of environmental conditions, human activity, and system responses to those factors. The Urban Digital Twins DWG, 3D Information Management DWG, and the Autonomy, Sensors, Things, Robots, and Observations DWG are each actively discussing and collaborating on this integration.

      Ethics in Geospatial. The OGC Executive Planning Committee has established a new subgroup on Ethics in Geospatial to set strategy for how OGC might address/respond to the ethical use of geospatial data or the use of those data for ethical purposes. The group will organize an initial meeting this July. If you would like to contribute to the conversation, you can sign up to the OGC Ethics in Geospatial email list here.

      Opening Plenary

      The Opening Plenary was hosted by OGC’s Dr. Rachel Opitz and featured a keynote presentation from Eric Loubier, Director General of the Canada Centre for Mapping and Earth Observation at Natural Resources Canada. Mr. Loubier highlighted the use of geospatial data and technologies to address the needs of Canadian citizens, with examples including flood and wildfire risk. 

      Introductory messages were then delivered by Louis-Martin Losier from Bentley Systems, Gordon Plunkett from Esri Canada, Hermann Brassard from CAE, and Dean Hintz from Safe Software. Finally, Prashant Shukle, Chair of the OGC Board of Directors, presented on “Canada and the OGC – 30 years of impact,” which reflected on the important parts that Canadian organizations have played in OGC’s 30 year history.

      Special tribute was then paid to an instrumental figure in OGC’s history who sadly passed away in May this year, Dr. John Herring. John was OGC’s first Gardels Award recipient back in 1999, and also received an OGC Lifetime Achievement Award in 2021.

      Chair of the OGC Board of Directors, Prashant Shukle, presents “Canada and the OGC – 30 years of impact” during the opening session. Future Directions

      This Meeting’s Future Directions session focused on Artificial Intelligence in Geoinformatics. Four presentations were made to provide updates since this topic was last addressed.

      • Leveraging AI for Geospatial Reality Data: Louis-Martin Losier, Jeroen Vermeulen, Arnaud Durante (Bentley Systems)
      • Spatial Web: AI agents operating in hyperspace: George Percivall (GeoRoundtable / IEEE GRSS)
      • A User-Centric Process to Build AI-Powered Geospatial Applications: Pablo Fuentes (makepath)
      • Bringing Geospatial Awareness to Large Language Models Using Spatial Knowledge Graphs: Nathan McEachen (TerraFrame)

      The four presenters then engaged in a fascinating panel discussion moderated by Dr. Gobe Hobona of OGC. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      Meeting Special Sessions

      The Methane Summit focused on the observation, measurement, monitoring, and spatial analysis of methane emissions. Consistent reporting of these emissions in a spatial context is key to effective decision making regarding reduction of emissions and their environmental consequences. Hence, the session also resulted in the proposal of a new OGC Standards Working Group (SWG) for EmissionML as a means to encode emission data. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      Directly following the Methane Summit was a linked Sensor Summit to talk more specifically about sensor model and data standardization. The focus of this Summit was on new and emerging Standards activities in OGC, including SensorThings API version 2.0, OGC API – Connected Systems and its dependent updates to the SensorWeb Standards, and the UK SAPIENT sensor architecture. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      The OGC Canada Forum held sessions on both Monday and Tuesday. Day 1 included an opening and the Forum Overview, followed by a panel on “The Transformative Role of Industry in National Geospatial Strategy and Spatial Data Infrastructure.” Day 2 started with an Oxford debate on the impact of standards on innovation and then included a panel on “National Geospatial Strategy in a Time of Rapid Change and Growing Challenges.”  The day wrapped up with a discussion on partnerships and a closing. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      (L-R) Claudine Couture, Linda van den Brink, Bradford Dean, Eldrich Frazier, and Eric Loubier discussing “National Geospatial Strategy in a Time of Rapid Change and Growing Challenges” during the Canada Forum.

      The Quantum Computing ad hoc session was a follow-up from the previous Member Meeting to assess whether a new OGC Working Group should be established to assess the geospatial role of quantum computing technologies. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      On Friday of the meeting week, a full-day Metadata Workshop was organized by the Metadata and Catalogs Domain Working Group (DWG). The first half of the workshop set the stage with presentations on current and emerging metadata Standards as well as their practical use. The second half of the summit was focused on the candidate OGC GeoDCAT Standard, how GeoDCAT fits within OGC’s building block approach to Standards, and preparation for a metadata-centric OGC Code Sprint later in 2024. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      The next OGC Testbed has now begun! The Testbed-20 kickoff session helped participants better understand sponsor requirements and introduced both parties to the process by which OGC will manage the Testbed. As the largest Research & Development (R&D) Initiatives conducted under OGC’s COSI Program, OGC Testbeds exist at the cutting edge of technology, actively exploring and evaluating future geospatial technologies to solve today’s problems. 

      Testbeds provide an opportunity to engage with and lead the latest research on geospatial system design, concept development, and rapid prototyping. They also provide a business opportunity for stakeholders to mutually define, refine, and evolve service interfaces and protocols in the context of hands-on experience and feedback. The solutions developed in Testbeds eventually move into the OGC Standards Program, where they are reviewed, revised, and potentially approved as new international Open Standards that can reach millions of individuals.

      Testbed-20 will drive innovation at the foundations of geospatial data ecosystems. While working across four tasks, participants will collaborate to create mechanisms that improve Integrity, Provenance, and Trust (IPT) in geospatial data systems and workflows; transform Standards for GEOINT Imagery Media for Intelligence, Surveillance, and Reconnaissance (GIMI); enhance the usability of, and investigate new applications for, GeoDataCubes; and explore options for High-Performance Geospatial Computing Optimized Formats.

      The OGC Executive Planning Committee during their visit to the CAE Factory. Closing Plenary

      Wrapping up the week, I opened Thursday’s Important Things session with a rapid, 7-minute summary of the entire meeting week. This presentation was followed by some introductory remarks from Ryan Ahola of Natural Resources Canada to identify issues with Spatial Data Infrastructures (SDIs) and domains requiring geospatial standardization. Member discussion focused primarily on ensuring that SDI planning and management be aware of the larger data ecosystems in which the SDI must exist. This topic then led into a more detailed discussion on the mechanics of communicating how users should look to transition from the legacy OGC Web Services to OGC API Standards, where appropriate. OGC Members can access the presentations and a recording, including of the 7-minute overview, on this page in the OGC Portal. Additionally, OGC Members can access as session notes on the “Important-Things-2024-06” Etherpad.

      The Closing Plenary then saw a keynote from Jong Tae Ahn of the Republic of Korea’s Ministry of Land, Infrastructure and Transport that briefed the long-term roadmap for spatial information standardization in Korea. The remainder of the session was dedicated to advancing Standardization activities in OGC. Slides and content from a large number of Working Group sessions were included. OGC Members can access the presentations and a recording on this page in the OGC Portal.

      Ander Andersen is another new contributor. He kicks off with marker for the geographic center of the US. UK readers please forgive the US spelling of what should be “centre” but given the location I thought I should follow their convention.

      Of course anything that claims to be the geographic centre of a country or polygon is going to prompt some discourse in the geo community. The marker has Lat 39 degrees 50 minutes, Long 98,35 but, as you might expect Wikipedia has a whole article about the different options – this marker is at the centre of the 48 contiguous states and located Lebanon, Kansas

      If you include Alaska and Hawaii the centre shifts to Lat 44,58, Long 103,56 which is north of Belle Fourche in South Dakota.

    • sur QGIS Swiss Locator 3.0 brings elevation profiles and vector tiles

      Posted: 25 June 2024, 6:43am CEST
      Swiss elevation profiles

      Get high-precision elevation profiles in QGIS right from Swisstopo’s official profile service, based on swissALTI3D data!

      Swiss elevation profiles are available with QGIS 3.38.

      Thanks to this integration, you can take advantage of existing QGIS features, such as exporting 2d/3d features or distance/elevation tables, as well as displaying profiles directly in QGIS layouts.

      Tip: Swiss elevation profiles will be available as long as the Swiss Locator plugin is installed and active. Should you need to turn Swiss elevation profiles off to create other profiles with your own data, go to the Plugin manager and deactivate the plugin in the meantime.

      For developers

      We’re paving the way for adding custom elevation profiles to QGIS. For that, we’ve added a QGIS profile source registry so that plugin developers can register their own profile sources (e.g., based on profile web services, just like we did here) and make them available for QGIS end users. The registry is available from QGIS 3.38. It’s your turn! ???

      Thanks to the QGIS user group Switzerland for funding this feature! ?

      Swiss vector tiles base maps

      Loading Swiss vector tiles is now easier than ever. Just go to the locator bar, type the prefix “chb” (add a white space after that) and you’ll get a list of available and already styled Swiss vector tiles layers. Some of them will even load grouped auxiliary imagery for reference.

      Vector tiles will be loaded at the bottom of the QGIS layer tree as base maps, so you will see all your data on top of them.

      Vector tiles are optimized for local caching and scale-independent rendering. This also makes it a perfect fit for adding it to your QField project.

      There are a couple of different vector tile sets available:

      leichte-basiskarte Light base map

      Similar to the leichte-basiskarte layer, but using an older version of the data source and adjusted styles.

      leichte-basiskarte-imagery (with WMTS sublayer) Imagery base map (with WMTS sublayer)

      This layer is similar to the leichte-basiskarte-imagery layer, but it uses an older version of the data source and adjusted styles.

      Base map

      See the official services documentation for details on data sources and styles.


      Thanks to your feedback, we’ve also fixed some issues. Don’t hesitate to reach out to us at GitHub if you’d like to suggest or report something related to the Swiss Locator plugin.

      Happy (and now more powerful) mapping! ??

      Posted: 20 June 2024, 3:00pm CEST by Simon Chester

      Last night at the 129th Open Geospatial Consortium (OGC) Member Meeting, held in Montreal, Canada, Andreas Matheus was presented the OGC’s prestigious Kenneth D. Gardels Award. The Gardels Award is presented each year to an individual who has made exemplary contributions to OGC’s consensus standards process. The Gardels Award was conceived to memorialize the spirit of a man who dreamt passionately of making the world a better place through open communication and the use of information technology to improve the quality of human life.

      Andreas Matheus, Managing Director at Secure Dimensions GmbH, was selected by previous Gardels Award winners as the 2024 recipient because of his persistent efforts to ensure best practices in security and API design in OGC.

      A member of the nominating committee commented that Andreas has “been the go-to security expert for almost as long as OGC has existed.” Another committee member noted that Andreas’ “dedication on security and citizen science has been constant” and that he is “fully focused on promoting OGC solutions and other Standards for security.”

      “The OGC Board of Directors thanks Andreas for his work as a chair and active member of many OGC Working Groups and for providing his insight and expertise to several OGC Standards and Collaborative Solutions and Innovation (COSI) initiatives,” commented Prashant J. Shukle, Chair of the OGC Board of Directors. “Your tireless voice of expertise on security matters continues to be critical to OGC activities and exemplifies the values associated with the Gardels Award.”

      Andreas Chairs the OGC Security, Citizen Science, and Blockchain & Distributed Ledgers Domain Working Groups as well as the GeoXACML and OWS Common – Security Standards Working Groups. Andreas is also the principal editor for several OGC Testbed Engineering Reports and both the GeoXACML and OWS Web Services Security Standards.

      In all this work, Andreas exemplifies the highest values of OGC, and has demonstrated the principles, humility, and dedication in designing, supporting, and promoting spatial technologies to address the needs of humanity that characterized Kenn Gardels’ career and life.

      About the OGC Gardels Award
      The Kenneth D. Gardels Award is a gold medallion presented each year by the Board of Directors of the Open Geospatial Consortium, Inc. (OGC) to an individual who has made exemplary contributions to OGC’s consensus standards process. Award nominations are made by members – the prior Gardels Award winners – and approved by the Board of Directors. The Gardels Award was conceived to memorialize the spirit of a man who dreamt passionately of making the world a better place through open communication and the use of information technology to improve the quality of human life.
      Kenneth Gardels, a founding member and a director of OGC, coined the phrase “Open GIS.” Kenn died of cancer in 1999 at the age of 44. He was active in popularizing the open source Geographic Information System (GIS) ‘GRASS’, and was a key figure in the Internet community of people who used and developed that software. Kenn was well known in the field of GIS and was involved over the years in many programs related to GIS and the environment. He was a respected GIS consultant to the State of California and to local and federal agencies, and frequently attended GIS conferences around the world.
      Kenn is remembered for his principles, courage, and humility, and for his accomplishments in promoting spatial technologies as tools for preserving the environment and serving human needs.

      Posted: 20 June 2024, 6:45am CEST

      During the pandemic, people noticed how well they could work remotely, how productive meetings via video call could be, and how well webinars worked. At, this wasn’t news because we have always been 100% remote. However, we missed the unplanned, in-person interactions that occur during meetups with a ?or ?. That’s why we’re very pleased that last week we could join the Swiss QGIS user day for the second time after the pandemic. has been invested in QGIS since its inception in 2014, actually even before; our CEO Marco started working with QGIS 0.6 in 2004 and our CTO Matthias with version 1.7 in 2012. Since 2019, we have also been the company with the most core committers. We can definitely say that has been one of the main driving forces behind the large adoption of QGIS in Switzerland and worldwide. 

      Contributions to the QGIS core measured in commit numbers

      Looking at the work done in the QGIS code we’re by far the most prolific company in Switzerland and second worldwide only to North Road Consulting. On top of it, we were the first – and still only one of two- companies to sustain at a Large level since 2021.

      This makes us very proud and it is why we’re even happier to see how much that is happening around QGIS in Switzerland aligns with the visions and goals we set out to reach years ago.

      The morning started with a presentation by our CTO Matthias “What’s new in QGIS” featuring plenty of work sponsored by the Anwendergruppe CH.

      Our CTO Matthias answering QGIS questions

      DXF Improvements, the release of SwissLocator 3.0 with swissalti3d and vector tiles integration, and an update on the advances towards solid curve handling in QGIS, a prerequisite for properly handling AV data in Switzerland, were only some of the many noteworthy points he touched.

      The highlight of Matthias’ presentation was the better OGC API Features support in QGIS, which was also highlighted in a subsequent talk about Kablo, showing how the next generation of industry solutions (Fachschalen) will be implemented.

      Slides: Neues aus der QGIS Welt - QGIS Anwendertag 2024

      Following was a short presentation on the project DMAV, Christoph Lauber introduced a project that aims to implement an industry solution for official cadastral surveying with QGIS.

      Andreas Neumann from ETH Zurich and Michael presented the qgis-js project. QGIS-js is an effort to port QGIS core to WebAssembly so that it can be run in a web browser. Although still in the early experimentation phase, this project has great potential to leverage interesting new use cases that weren’t even thinkable before.

      By applying a middleware based on OGC API Features and Django, Kablo shows how common limitations of current industry solutions (like permission management and atomic operations) can be overcome and how the future brings desktop and web closer together.

      Slides: kablo-qgis-user-days

      Obviously, it wasn’t just Sandro Mani from Sourcepole presented the latest and greatest improvements on QWC2, like street view integration and cool QGIS features brought to a beautiful web gis. Andreas Schmid from Kt. Solothurn presented how cool cloud-optimized geotiff (COG) is and what challenges come with it. Interested in the topic? Read more in our report about cloud optimized formats. Mattia Panduri from Canton Ticino explained how they used QGIS to harmonise the cantonal building datasets and Timothée Produit from IG Group SA presented how pic2map helps bring photos to maps. 

      To round up the morning, Nyall Dawson from North Road Consulting did a live session around the world to show the latest developments around elevation filtering in QGIS.

      In the afternoon, workshops followed. Claas Leiner led a QGIS expression one while Matthias and Michael showed how to leverage QGIS processing for building geospatial data processing workflows. 

      The first QGIS model baker user meeting took place in the third room. The participants discussed this fantastic tool we developed to make INTERLIS work smarter and more productive.

      First ModelBaker user meeting

      It was a very rich and constructive QGIS user day. We came home with plenty of new ideas and a sense of fulfilment, seeing how great the community we observed and helped grow has become.

      A big thanks go to the organisers and everyone involved in making such a great event happen. Only the beer in the sunshine was literally watered by the rain. Nevertheless, there were exciting discussions in the station bistro or in the restaurant coaches on the way home.

      Many of the stories were documented on the circular posterds by those who made the journey, or by their families. The postcards then inspired pupils at Martin Primary School to create poetry on the theme of migration, some of which are displayed here inside the birds.

    • sur Marco Bernasocchi: Supercharge your fieldwork with QField’s project and app-wide plugins

      Posted: 18 June 2024, 6:45am CEST

      This blog post will introduce QField’s brand new plugin framework and walk through the creation of a plugin to support bird watchers in need of a quick way to digitize photos of spotted birds onto a point vector layer.

      QField Plugin Snap! in action A plugin framework is born!

      As announced recently, QField now empowers users through a brand new plugin framework allowing for simple customization on the way the application behaves or looks all the way through to creating completely new functionalities.

      The plugin framework relies on Qt’s QML engine and JavaScript, allowing for cross-platform support out of the box. This means that plugins will run perfectly fine on all platforms currently supported by QField: Android, iOS, Windows, Linux, and macOS.

      App-wide plugin vs. project plugin

      First, let’s look at the two types of plugins supported by QField: app-wide plugins and project plugins. As their names imply, the main difference is their scope. An enabled app-wide plugin will remain active as long as QField is running, while project plugins are activated on project load and deactivated when the project tied to the plugin is closed.

      Project plugins are shipped alongside a given project file (.qgs/.qgz). Project plugins must share the same name of the project file with a .qml extension. For example, if your project file is birdwatcher.qgz, QField will look for the presence of a birdwatcher.qml to activate the project plugin. For app-wide plugins, installation is done via the plugins manager popup; more on this below.

      Distribution of project plugins can be greatly facilitated through QFieldCloud. The presence of project plugins within a cloud project environment will be automatically detected and packaged alongside the project file and its datasets when deployed to QField devices.

      Starting with a project plugin

      We will start with looking into a simple project plugin that offers a new digitizing mechanism focused on snapping photos as a trigger for point feature addition. This plugin will demonstrate how new functionalities and behaviors can be added to QField to serve specific needs. In this case, the new digitizing mechanism could come in handy for bird watchers and other users in need of a quick way to snap photos!

      It’s advised to download a version of QField running on your desktop environment while testing plugins. Links to Windows, Linux, and macOS builds are available here. Once installed, download this project archive containing a tiny birdwatcher sample project and extract it into a new directory on your local machine.

      The project archive consists of a point vector layer (observations.gpkg), a project file (birdwatcher.qgz) as well as a project plugin (birdwatcher.qml) which we will look into below. Please note that the point vector layer’s attribute form is already configured to display captured photos. We will not spend time on attribute form setup in this post; see this relevant documentation page if you are interested in knowing how that was achieved.

      We can now test the project plugin by opening the project (birdwatcher.qgz) in QField. Users familiar with QField will notice a new ‘camera’ tool button present on the top-right corner of the map canvas. This button was added by the project plugin. You can press on it, to open the QField camera, take a photo (of yourself, a random object on your table, or with a bit of luck a bird), and witness how that leads to a point feature creation.

      Digging into the project plugin file

      Let’s open the project plugin file (birdwatcher.qml) in your favorite text editor. The first few lines define the QML imports needed by the plugin:

      import QtQuick
      import QtQuick.Controls
      import org.qfield
      import org.qgis
      import Theme
      import "qrc:/qml" as QFieldItems

      Beyond the two QtQuick imports, we will make use of QField-specific types and items as well as QGIS ones (registered and declared in this source file), a Theme to retrieve icons and colors as well as QField items such as tool buttons (see this source directory), as well as the QField QML items embedded into the application itself to make use of the camera.

      The next line declares an generic Item component which will be used by QField to initiate the plugin. This must be present in all plugins. As this plugin does, you can use the Component.onCompleted signal to trigger code execution. In this case, we are using iface to add a tool button on top of the map canvas:

      Component.onCompleted: {

      Just above these lines, the plugin declare a number of properties pointing to items found in the main QField ApplicationWindow:

      property var mainWindow: iface.mainWindow()
      property var positionSource: iface.findItemByObjectName('positionSource')
      property var dashBoard: iface.findItemByObjectName('dashBoard')
      property var overlayFeatureFormDrawer: iface.findItemByObjectName('overlayFeatureFormDrawer')

      Users can reach through to any items within QField’s ApplicationWindow provided they have an objectName property defined. The string value is used in the iface.findItemByObjectName() function to retrieve the item.

      The rest of the file consists of a loader to activate the QField camera, a tool button to snap a photo, and a function to create a new feature within which the current position is used as geometry and the snapped photo is attached to the feature form.

      The function itself provides a good example of what can be achieved by using the parts of QGIS exposed through QML, as well as utility functions and user interface provided by QField:

      function snap(path) {
        let today = new Date()
        let relativePath = 'DCIM/' + today.getFullYear()
                                    + (today.getMonth() +1 ).toString().padStart(2,0)
                                    + today.getDate().toString().padStart(2,0)
                                    + today.getHours().toString().padStart(2,0)
                                    + today.getMinutes().toString().padStart(2,0)
                                    + today.getSeconds().toString().padStart(2,0)
                                    + '.' + FileUtils.fileSuffix(path)
        platformUtilities.renameFile(path, qgisProject.homePath + '/' + relativePath)
        let pos = positionSource.projectedPosition
        let wkt = 'POINT(' + pos.x + ' ' + pos.y + ')'
        let geometry = GeometryUtils.createGeometryFromWkt(wkt)
        let feature = FeatureUtils.createFeature(dashBoard.activeLayer, geometry)
        let fieldNames = feature.fields.names
        if (fieldNames.indexOf('photo') > -1) {
          feature.setAttribute(fieldNames.indexOf('photo'), relativePath)
        } else if (fieldNames.indexOf('picture') > -1) {
          feature.setAttribute(fieldNames.indexOf('picture'), relativePath)
        overlayFeatureFormDrawer.featureModel.feature = feature
        overlayFeatureFormDrawer.state = 'Add'

      The QGIS API Documentation site is a good resource for learning what parts of the many QGIS classes are exposed to QML. For example, the QgsFeature documentation page contains a Properties section and a Q_INVOKABLE prefix next to functions indicating their availability within a QML/JavaScript environment.

      Deployment of a project plugin via QFieldCloud

      As mentioned above, QFieldCloud greatly eases the deployment of project plugins to devices in the field. We will now go through the steps required to create a cloud project environment based on the birdwatcher sample project, and witness it handling the project plugin automatically.

      This will require you to registered for a freely available QFieldCloud community account if you haven’t done so yet (it takes a minute to do so, what are you waiting for ? ). We will also need the QFieldSync plugin in QGIS, which can be enabled through the QGIS plugin manager.

      Let’s open QGIS, and log into QFieldCloud by clicking on the QFieldSync toolbar’s blue cloud icon. Once logged in, click on the ‘Create New Project’ tool button found at the bottom of the dialog.

      In the subsequent panel dialog, choose the ‘Create a new empty QFieldCloud project’ and then hit the ‘Next’ button. Give it a name and a description, and for the local directory, pick the folder within which you had extracted the birdwatcher project, then hit the ‘Create’ button.

      QFieldSync will then ask you to upload your newly created cloud project environment to the server. Notice how the project plugin file (birdwatcher.qml) is part of the files to be delivered to the cloud. Confirm by clicking on the ‘Upload to server’ button.

      When QFieldSync is finished uploading, you are ready to take your mobile device, open QField, log into your QFieldCloud account and download the cloud project. Once the cloud project is loaded, you will be asked for permission to load the project plugin, which you can grant on a permanent or one-time basis.

      Bravo! You have successfully deployed a project plugin through QFieldCloud.

      Creating an app-wide plugin directory

      Let’s move on to creating a functional app-wide plugin directory. Download this sample app-wide plugin and extract it into a new directory placed in the ‘plugins’ directory, itself found within the QField app directory. The location of the app directory is provided in the ‘About QField’ overlay, take note of it prior to extracting the plugin if you have not done so yet.

      As seen in the screenshot above, which demonstrates the directory hierarchy, a given plugin directory must contain at least two files: a main.qml file, which QField will use to activate the plugin, and a metadata.txt file containing basic information on the plugin, such as the plugin name, author details, and version.

      Here’s a sample metadata.txt from the birdwatcher project plugin upgraded into an app-wide plugin:

      description=Digitize points through snapping photos

      Opening main.qml in your favourite text editor will reveal that it has the exact same content as the above-shared project plugin. The only change is the renaming of birdwatcher.qml to main.qml to take into account this plugin’s app-wide scope.

      PSA: we have setup this GitHub QField template plugin repository to ease creation of plugins. Fork at will!

      Deploying app-wide plugins

      While currently not as smooth as deploying a project plugin through QFieldCloud, app-wide plugins can be installed onto devices using a URL pointing to a zipped archive file containing the content of a given plugin directory. The zipped archive file can then be hosted on your own website, on a GitHub or GitLab repository, a Dropbox link, etc.

      In QField, open the plugins manager popup found in the settings panel, and use the ‘Install plugin from URL’ button to paste a URL pointing to a zipped plugin file.

      You should keep the zipped archive file name consistent for a better user experience, as it is used to determine the installation directory. This is an important consideration to take into account when offering plugin updates. If your zipped plugin file name changes, the plugin will not be updated but rather added to a new directory alongside the previously installed plugin.

      QField does allow for a version tag to be added to a zipped archive file name, provided it is appended at the end of the file name, preceded by a dash, and includes only numbers and dots. For example, and will install the plugin in the myplugin directory.

      Empowering users as well as developers

      Here at, we believe this new plugin framework empowers not only users but also developers, including our very own ninjas! With plugin support, we now have the possibility to develop answers to specific field scenarios that would not necessarily be fit for QField-wide functionalities. We would love to hear your opinion and ideas.

      If you would like to supercharge your fieldwork and need some help, do not hesitate to contact us – your projects are our passion ?

      P.S. If you are developing a cool QField plugin, also let us know! ?
