GRASS GIS: GRASS GIS 8.4.0 released
sur Planet OSGeoWhat’s new in a nutshell The GRASS GIS 8.4.0 release contains more than 520 changes compared to 8.3.2. This new minor release includes important fixes and improvements to the GRASS GIS tools, libraries and the graphical user interface (GUI), making it even more stable and robust for daily work. Most importantly: location becomes project: The Python API, command line, and graphical user interface are now using project instead of location for the main component of the data hiearchy while maintaining backward compatibility. -

Jorge Sanz: Elastic Volunteering Time Off
sur Planet OSGeo
My employer, Elastic, has a number of philanthropic initiatives but definitely the one I love the most is the Volunteering Time Off (VTO). We are given 40 hours per year from our working hours to contribute to projects and initiatives we care about. Employees have full freedom to choose what they want to do with that time and are encouraged to use it.
In my case, over this almost 5 years I have to admit I haven’t used all that time every year but I tried to get the most of it. During COVID I did some remote work for a local NGO that works for fair trade, giving them a webinar about Open Source among other things (see update from December 2019 and following months). I also spent a few days working on some admin tasks for the Open Source Geospatial Foundation and I’ve already written here about a couple sessions I did for Cibervoluntarios, training seniors and teens about safe browsing and email.
Last week I was showcased in the company blog, along with other colleagues, on different projects to contribute to. In my case, last year I joined the mapping efforts after the Morocco Earthquake and took a full day mapping roads and streets of a rural area, as part of the coordinated efforts from the Humanitarian OpenStreetMap team (reported on my October community update). I’m very happy to have this support from my employer to leave things aside when an emergency like this arises, granted there are no other urgent issues at work.
As a personal call to action, I’d love to get back to Cibervoluntarios activities. This year has been quite busy; let’s see after summer if there’s room for getting out and engaging with them.
I know I haven’t updated this site in a while, I’ll write one soon! ?

QGIS Blog: Introducing the new QGIS.org website
sur Planet OSGeoWe have a new website!
We recently launched our new website at QGIS.org. It is a ground-up overhaul and provides a fresh take on the first contact point for existing or potential users wishing to engage with the QGIS project and discover its value proposition.
A new strategy for QGIS.org websites
In this blog post, we would like to provide an overview of the goals that we had for building the new QGIS.org website and the bigger picture of how this website update fits into the broader strategy for our website plans for QGIS.
About two years ago, we started experimenting with building a new QGIS.org website based on Hugo. Hugo, as a technology choice, was less important than was our intent to develop a more modern site that addressed our strategic goals.
After some ‘in-house’ (i.e. volunteer-based) work to develop an initial version of the site, we received the go-ahead to use QGIS funds for this and put out a call in October 2023 for a company to support our work. This was ultimately won by Kontur.io, who, together with our volunteers, brought the work into high gear.
Initial analysis of the questions and actions to be quickly answered by qgis.org
Goal 1: Speak to a new audience
Our primary goal was to speak to a new audience. We are confident that QGIS can compete with all of the commercial vendors providing GIS software. We didn’t convey that well on our old website. We feel that QGIS was too apologetic in how it presented itself. We wanted a website which inspires confidence while addressing the needs of a corporate or organisational decision-maker who is looking at the QGIS project during their GIS software selection process.
The old website was very focused on the developer and contributor community. Obviously, those aspects are important since, without our fantastic community, the QGIS project would not exist. The messaging around open source is also important. Yet these ideas are secondary to the idea that QGIS is one of the best (if not the best) desktop GIS applications out there on the market – open-source or otherwise. We need to present it in this professional perspective.
So, the first goal was to change the messaging to focus on QGIS’s value proposition and take a very professional approach to presenting ourselves on the website.
User group and requirements analysis for the potential qgis.org visitors
Goal 2: Harmonisation
The second goal was to start the process of harmonising all of our website properties. QGIS.org, over the years, has built many different web properties. For example, there’s the plugins website, the feed, the changelog, the sustaining members website, the lessons website and the certification website, the new resources hub website, the API documentation, the user documentation, the user manual, the training manual, various other documentation efforts, and more. Some of those are combined in one application, There are also some less well-known resources, like our analytics.qgis.org and another one for plugin analytics. In short, we’ve a lot of resources!
With so many different web properties, they’ve devolved over time: each has its own look and feel, navigation approach and how you interact with it. Some of them were translated, and some of them were not. We want to harmonise all of these sites so that the user does not notice any change in user experience when they move from one QGIS-related site to another.
Goal 3: Harmonising deployment
In the underlying process of these changes, we’re also redeploying all of the websites on new servers, which are more up-to-date and use better security and maintenance practices. Plenty of work is happening in the background to ensure that all of the servers are in a better-maintained state, document how they’re maintained, and so on.
Goal 4: A hub and spokes
The objective of the new site design is to allow quick movement between the QGIS auxiliary sites. The QGIS.org site will form a hub that effortlessly takes visitors to whichever QGIS-related site they need to complete the task they are busy with. If you’re moving between these sites, the experience should be seamless. You should not really even be aware that you’re moving between different websites. Other than looking at the URL bar, the user presentation and experience should be harmonious between all of them.
One way we are planning to achieve this is to have a universal menu bar and footer. You will see that in the new website’s design, there is a menu bar across the top. This menu bar has two levels: the top menu and the second level, where the search bar is.
The universal menu bar
In this second row, auxiliary sites will have their own sub-menu whilst keeping the shared top-level menu. So if you, for example, are moving around in plugins and want to review the plugin list or submit a new plugin, all of that navigation will be on the second line where the search bar is currently. Regardless of which subdomain you are on, the top-level menu bar will be the same, allowing you to easily navigate back to the hub or to another subdomain.
The footer will be unified and shared between all sites, and the cascading style sheets and styling will be unified across all of the QGIS websites.
In the next phase, we will work to achieve this coherence across all the websites, though we still have a few more tweaks to make to the qgis.org site first.
Goal 5: DOTDOTW – do one thing, do one thing well
We plan to break some auxiliary websites apart into separate pieces. So, for example, the changelog management, certification management, sustaining members management, and lessons management are all in one Django app. We will split them into small single-purpose applications using some common UX metaphors so that each is a standalone application that makes it easy for a potential contributor to understand everything the application does. This will also simplify management as we can upgrade each auxiliary site on separate development cycles. We will also finally have semantic URLs, e.g. certification.qgis.org, to take you to the different areas of interest on the site.
The plugins.qgis.org is also going to be refactored so that it just has plugins and not the resource sharing we’ve added in the last few years. The resource sharing will go into its own subdomain. Similarly, the Planet website will get split into its own website (the planet is a blog aggregator or RSS aggregator) that will be in its own managed instance. Some other components (like the analytics) are difficult to split out like this because they’re linked to the same database. We will try to make sure that those are more discoverable and theme them as much as possible to match the rest of the website experience.
Goal 7: Encapsulation
Another goal we had for the QGIS.org makeover was to make the site performant and self-contained. By self-contained, we mean that it should not ‘call’ out to CDN, Google or other platforms for resources like fonts, CSS frameworks, javascript libraries, etc. There were two reasons for this:
- These platforms often use such resources to track users as they move around the Internet, which we want to avoid as much as possible.
- We want to wholly manage our site, be able to fix any issues independently and generally follow a path of self-determination.
Our approach also facilitated the creation of a very performant website, as you can see here. We will try to adhere to these principles for the auxiliary site updates we do in the future, too.
What about translations?The question has come up: Why did we not want to translate the new QGIS.org when it was translated before?
Firstly, we should make it clear that we do not plan to remove translations from the user documentation, the user manual, and so on, where we think they have the most value.
For the main QGIS.org site, we question whether there is a high value in translating it. Here are some reasons why:
1. Lingua franca: If you are an IT manager in a non-English-speaking country and you want to evaluate some software, you’re going to run into a product page that presents itself in English – it is the norm for IT procurement to work in English for reviewing software products and so on.
2. Automation: Automated translations inside browsers are getting better and better. While these translations are still not completely adequate, we think they will be in one or two years’ time.
3. Translation integrity: Our pursuit of Goal 1 means that we would no longer find it acceptable to have partial website translations. We also need to ensure that the wording and phrasing are consistent with the English messaging. We also have concerns about the QA process regarding trust and review – we want to ensure that any translation truly reflects the meaning and intent of the original content and has not been adjusted during the translation process.
4. Cohesion: Our most important point is raised if we go back to this idea of cohesion between the different websites like QGIS.org, plugins.qgis.org and so on. As well as having the same styling, we also don’t want to switch between languages as you hop between the sites. We aim to present them all as one site. If we translate QGIS.org and then take you to our auxiliary sites, e.g., plugins.qgis.org, the feed, or certification pages, which are in English only, the experience is jarring.
So we must either translate everything into all of the same languages, or work in English. Translating everything is a mammoth task for the translators and for us to retrospectively add translation support to each platform. Thus, we prefer the approach of harmonising everything to one language and then focusing our translation efforts on three areas:
- The application itself,
- the user manual and
- the training manuals.
We can leave the rest of the experience in English and instead focus on harmonising, for now, both in terms of look and feel and the technology used.
When we consider everything as one big website and what the bigger plan is, it is hopefully clearer why we didn’t think translating the landing page and QGIS.org was the best approach.
Further funded workWe hope to use more QGIS funding to support this work in the future. We’re also hoping to work again with Kontur to start moving all these auxiliary sites into their own projects, applying our style guidelines to each. Independently of that, Tim (volunteer), Lova (QGIS funded), and others are already getting started with this process.
Helping outDo you have strong opinions about the website? Contact Tim on the PSC mailing list if you would like to get involved as a volunteer. We would love to hear from designers, word smiths, marketers, information architects, SEO specialists, web developers and those who think they can help us achieve our goals.
ConclusionWe hope our goals and process make sense for everybody and that we were able to lay out a clear, logical argument about why we don’t want to translate the new website quite yet. We want to focus on these overarching goals and then return to them later if they are still a priority for people. Everything we have built is Open Source and available at this repo, where you can also find an issue tracker to report issues and share ideas relating to the new website.
Thanks for reading. Go spatial without compromise
Cheers, Tim, Marco and Anita

SourcePole: Adding external WMS to the QGIS Cloud Web Map
sur Planet OSGeoThe use of WMS/WMTS layers in a QGIS Cloud map project can significantly degrade the performance of the map display. I have already discussed how to counter this problem in an earlier post. One of the solutions is to load external WMS as background layers. The problem with this approach, however, is that only one WMS background layer can be loaded at a time. If further WMS layers are to be loaded into the map at the same time, this approach cannot be used. -

GeoServer Team: GeoServer 2024 Q3 Developer Update
sur Planet OSGeoThis is a follow up to 2024 roadmap post outlining development opportunities.
First of all thanks to developers and organisations that have responded with offers of in-kind contributions. This blog post is assessing current progress and outlines a way forward to complete the Java 17/Jakarta EE/Spring 6 upgrades.
This post highlights development activities that are available to be worked on today, along with interested developers and commercial support providers available to work on GeoServer roadmap items.
Spring Framework 6 TasksThe key challenge we are building towards is a spring-framework 6 update, ideally by the end of 2024 when the version we use now reaches end-of-life.
The tasks below are steps towards this goal.
Wicket 9 upgradeInterested Parties:
- Brad has been doing amazing work with the Wicket 9 upgrade and is in need of assistance.
- GeoCat has offered to do manual A/B testing when PR is ready for testing.
Activity:
- [GEOS-11275] Wicket 9 upgrade
- geoserver#7154
Spring Security 5.8 provides a safe stepping stone ahead of the complete spring-framework 6 upgrade and is an activity that can be worked on immediately.
Interested parties:
- Andreas Watermeyer (ITS Digital Solutions) offered to work on this activity in during the initial January call out, and has indicated they are now ready to start.
Activity:
- [GEOS-11271] Upgrade spring-security to 5.8
The spring-security-oauth client has reached end-of-life and a GeoServer OAuth2 support must be rewritten or migrated as a result.
There are two paths to migrate to spring-security-core implementation:
-
Option: Migrate the existing community module implementations to spring-security-core in place; with as little loss of functionality as possible. This has the advantage of using existing test coverage to maintain a consistent set of functionality during migration.
-
Option: Setup a community module alongside the existing implementation with the goal of making a full supported etension. This approach has the advantages of allowing organisations the ability to do A/B testing as both the old and new implementation would be available alongside each other. This has the advantage of allowing stakeholders to only fund, implement, test functionality as required without disrupting existing use.
Security integrations often require infrastructure to develop and test against, which the core GeoServer team does not have access to for automated tests. We would like to see organisations review their security integration requirements and be on hand to support this development activity.
The initial priority will support for OAuth2 and Open ID Connect (OIDC), parties interested in maintaining support for Google, GeoNode, GitHub are welcome to participate.
Interested Parties:
- Andreas Watermeyer (ITS Digital Solutions) offered to work on this activity, or test as needed.
- GeoCat is interested in this work also, with the goal of bringing the OIDC plugin up to full extension status (if financing is available).
Activity: not started
- [GEOS-11272] spring-security-oauth replacement, with spring-security 5.8
The image processing library used by GeoServer has been donated to the open source community under the name ImageN.
The immediate goal has been to add test cases to this codebase and make an ImageN 1.0 release. Andrea has come up with the amazing idea of integrating with JAI-Ext project immediately, to benefit from the improved operators, and jumpstart test coverage.
Interested Parties:
- Jody (GeoCat) is available to support this activity, or take lead if funding is available.
- Andrea (GeoSolutions) has had a deep dive into the implications for the JAI-EXT project outlining a roadmap for project integration
We would like to see organisations that depend on GeoServer for earth observation and imagery to step forward with funding for this activity.
2024 Financial support and sponsorshipThus far 2024 has not had a strong enough sponsorship response to support the project goals above. As a point of comparison we established a budget of $15,000 with OSGeo last year to take on an low-level API change that affected several projects.
This year GeoServer sponsorship has raised between $1,000 and $2,000 which is not enough to plan with or coordinate in-kind contributions offered thus far.
Jody has worked with the OSGeo board to make adjustments to the sponsorship:
- Guidance has been provided for appropriate sponsorship levels for individual consultants, small organisation, companies and public institutions of different sizes.
- There are clear examples of how to sponsor and donate, along with the the perks and publicity associated with financial support
- GeoServer has a new sponsorship page on our website collecting this information
- GeoServer now lists sponsors logos on our home page, alongside core contributors.
We would like to thank everyone who has responded thus far:
- Sponsors: How 2 Map, illustreets
- Individual Donations: Peter Rushforth, Marco Lucarelli, Gabriel Roldan, Jody Garnett, Manuel Timita, Andrea Aime

Ian Turton's Blog: Adding a spell check to QGIS
sur Planet OSGeoAdding 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,InteliJand 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.
ImplementationObviously 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
pyspellcheckwhich 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.@check.register(type=QgsAbstractValidityCheck.TypeLayoutCheck) 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/> <ul> """ for t in possibles: template += f"<li>{t}</li>\n" template += '</ul>' res.detailedDescription = template results.append(res) return resultsAnd 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
QgsAbstractValidityCheckwas 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.pyspellcheckcan 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
QgsAbstractValidityChecksince 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.checkerWhereby I can pull out the named plugin and grab it’s spell checker, which was created in the plugin’s
Future Work__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).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:]

KAN T&IT Blog: IOT Solution Congress en Brasil, nuestra experiencia
sur Planet OSGeoEl 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.

gvSIG Team: Acceptance Speech for the National Geographic Science Award
sur Planet OSGeoHonorable 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!

Free and Open Source GIS Ramblings: New MovingPandas tutorial: taking OGC Moving Features full circle with MF-JSON
sur Planet OSGeo
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-JSONBoth 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' )
Conclusion
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.

Mappery: Nikko on a Shopping Bag
sur Planet OSGeo
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
[https:]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

sur Planet OSGeoPièce jointe: [télécharger]
QField Rapid Mapper is a project for the QField mobile app, which allows emergency responders, civil protection, military, and citizens to assess and report damages from natural catastrophes by quickly sharing geolocated images, videos and audio. QField Rapid Mapper offers real-time data collection, mapping and sharing to help enhance disaster response and coordination.
Join the effort OPENGIS.ch Supports Flood Mapping Efforts in Ticino
QField and QFieldCloud are open-source, and OPENGIS.ch is donating the needed QFieldCloud infrastructure and expertise to help map the floods in Ticino in 2024After discussing with the Protezione Civile Locarno e Valle Maggia and the Centro di Competenza per la geoinformazione (CCGEO), we are proud to announce that OPENGIS.ch is donating the necessary QFieldCloud infrastructure and dedicated projects for a rapid crowdsourcing POC to aid in mapping the 2024 floods in Ticino. This crowdsourcing initiative aims to provide essential support to professionals and volunteers working on flood and landslide assessment and recovery.
Empowering Response with Advanced Technology What is needed?Photographing damaged houses and infrastructure is the most critical aspect of this mapping initiative. These images provide crucial information for assessing the extent of the damage, planning rescue and reconstruction operations, and ensuring that resources are allocated effectively. It’s also important to document any submerged or damaged vehicles, as they offer additional insights into the disaster’s impact. During these activities, it’s essential to be careful and respect the privacy and property of others, avoiding capturing license plate numbers or entering destroyed buildings without permission. Using QField Rapid Mapper can contribute to a faster and more coordinated emergency response while ensuring respect for those affected.
The QFieldCloud infrastructure enables efficient, real-time data collection and sharing, ensuring that accurate and up-to-date information is available to all stakeholders involved in the flood response. This effort underscores our commitment to leveraging technology for social good and environmental resilience.

Mappery: King David’s Tower 7 – Stefan Illes 3D Map of Jerusalem
sur Planet OSGeo
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.

The Madaba mosaic map is one of the oldest surviving maps of Jerusalem.
“A famous Byzantine mosaic map, discovered in 1896 in the town of Madaba in Jordan. The mosaic, dated to the sixth century, emphasizes Christian sites throughout the biblical lands. The map bears the names of the sites in Greek. In the center of the map, greatly enlarged, is a map of Christian Jerusalem”
Cartographers have superimposed an image of the Madaba map onto a modern map of the old city of Jerusalem and found that the mosaic was remarkably accurate
