En el vídeo anterior cargamos capas y trabajamos su representación visual. En este tercero vamos a lo que hay “detrás” de la geometría: la tabla de atributos. Cualquier capa en un SIG lleva asociada una tabla con los datos descriptivos de cada elemento, y aprender a moverse con soltura entre mapa y tabla es uno de los hábitos más útiles del trabajo diario.

Partimos de un proyecto con tres capas centradas en un caso muy habitual en la gestión municipal, la organización electoral: mesas electorales (puntos), ejes de carreteras (líneas) y distritos electorales (polígonos). De paso nos sirve para repasar los tres tipos de geometría con los que vamos a trabajar a lo largo del curso. Sobre los distritos aplicamos una simbología por valores únicos, esta vez clasificando por un campo de la propia tabla.

I’d like to introduce gitRmap: a semi-automated map of locations that you can add your own points to. It’s designed for people who are new to GIS, but who know a little bit of Git.

You can create a map like the one below, with your own pins on it, just by following the quick start at nickbearman.com/gitRmap.

If you get stuck, I want to know! Message me, email me or open an issue on GitHub.

I wanted to create a tool that made it easier for more people to make maps. There are plenty of tools out there for creating a web map, but for someone new to GIS they can be pretty intimidating.

Después de la entrega introductoria, en este segundo vídeo damos el salto a la parte práctica con gvSIG Desktop. Es la primera sesión aplicada del curso y empieza por el principio: dónde descargar gvSIG Desktop (la versión portable 2.7.0 para Windows o Linux) desde la web de SCOLAB, cómo realizar la configuración inicial básica del programa (idioma, sistema de referencia por defecto, unidades de mapa) y cómo se organiza la aplicación a partir del Gestor de proyecto y sus tipos de documentos: Vistas, Tablas, Mapas e Informes.

A partir de ahí abrimos una Vista nueva y empezamos a cargar información. Primero un ráster: una ortofoto del PNOA, viendo de paso la diferencia entre carga normal y carga por teselas. Después un vector: un shapefile de parcelas catastrales de Cullera, que colocamos sobre la ortofoto para tener una base municipal típica con la que trabajar.

Con este primer vídeo arrancamos el curso de manejo básico de la Suite gvSIG (Desktop, Online y Mapps) aplicado a la gestión municipal. Se trata de una entrega introductoria, dedicada a situar el contexto antes de entrar en la parte práctica de las próximas sesiones.

En él repasamos por qué la geomática tiene un peso creciente en los ayuntamientos y qué usos habituales encuentran los SIG en el día a día municipal: urbanismo y planeamiento, inventarios y patrimonio, infraestructuras y redes, o servicios a la ciudadanía. A partir de ahí presentamos qué es la Suite gvSIG y las dos piezas que protagonizan este vídeo: gvSIG Desktop, como herramienta de escritorio para el trabajo técnico (edición, análisis y cartografía), y gvSIG Online, orientada a publicar y compartir esa información en la web mediante geoportales y visores.

La información geográfica empieza a transformar una administración cuando deja de estar encerrada en documentos, mapas estáticos o sistemas aislados. La Infraestructura de Datos Espaciales de Uruguay es un gran ejemplo de ello. En el último año ha seguido ampliando su ecosistema de visualizadores temáticos, llevando la información geográfica oficial a ámbitos tan diversos como la justicia, la administración departamental, el deporte o la autoridad electoral.

En los últimos meses se han incorporado nuevos visualizadores en ámbitos tan diversos como:

Over the years, QField has gained a number of ways through which authors can share their mapping projects. This post looks at the multiple ways this can be achieved and what scenarios fit each method best.

QFieldCloud users all have the ability to configure their projects as ‘public’. When the option is turned on, all QFieldCloud users will be allowed to download and browse these maps at will.

These users coming in to view the map are given a reader role, prohibiting changes to the underlying datasets included in the project. This can be a great option when wanting to share maps to a large number of readers while relying on QFieldCloud to host the content and keep users up-to-date through synchronization.

On 3 June 2026, the European Commission adopted a new package of measures to strengthen Europe’s technological sovereignty.

The package includes two legislative proposals —the Chips Act 2.0 and the Cloud and AI Development Act— together with the European Open Source Strategy and a strategic roadmap for digitalisation and artificial intelligence in the energy sector.

GeoServer 3.0.0 release is now available with downloads (bin, war, windows), along with docs and extensions.

This is a stable release of GeoServer 3.0.x series. GeoServer 3.0.0 is made in conjunction with GeoTools 35.0, and GeoWebCache 2.0.0.

Thanks to Andrea Aaime (GeoSolutions), Jody Garnett (GeoCat), and Peter Smythe (AfriGIS) for making this release.

GeoServer 3.0 is now generally available. This post is not a feature announcement, those have been written, and the release notes cover the details. This is something we get to do less often: closing the loop on a promise. The modernisation work the community funded is finished and shipping, and we want to account for what that funding set out to achieve and what it delivered.

The result is a platform brought back onto a current, supported foundation. The work reached across the wider ecosystem rather than GeoServer alone, and the scope the campaign promised has been covered.

Here’s another QField release, packed with the features that have been at the top of professional surveyors’ wish list! (hint: it’s in the title) — plus improvements across the board for our wide range of users.

First up, NTRIP support has been added in QField unlocking sub-centimeter accuracy position readings without the need for any third-party app. This has long been requested by cadastral surveyors and other professional field workers in need of highly accurate data where being a few centimeters off can have real consequences.

To configure an NTRIP connection, simply connect to an RTK capable GNSS device via Bluetooth, BLE or TCP from the QField settings positioning panel. Once connected, the NTRIP user interface will be visible just below the positioning devices combo box in the same panel.

Thanks to Mario Ame

Everything was working fine. I had just finished building the Grow Your Own allotments map, deployed it to the live server, and was feeling pretty pleased with myself. A few days later a friend messaged me that the map had stopped working. No regions, just a blank basemap. Checked the console and got this:

“Server returned no content-length header or content-length exceeding request. Check that your storage backend supports HTTP Byte Serving.”

The current outbreak of Ebola has inevitably triggered lots of maps of the outbreak, just search for “Maps of the Ebola outbreak in Africa” and you will find something like this.

Some of these are pretty good, some don’t communicate very well and a few are awful. My attention was drawn to a static map obviously generated by AI which was so so bad that it was laughable and you had to wonder why anyone share this without picking up the numerous obvious geographic errors.

My wife grows some vegetables in our back garden, she used to have an allotment but she gave it up and we dug up part of our grass. I got to wondering about allotments and whether they were a British phenomena or they were widely spread? Which countries have the most allotments, growing space per capita and the largest size of allotments?

En la nueva versión de gvSIG Desktop, la 2.7, se han incluido tres herramientas que permiten crear geometrías de líneas y polígonos mediante rumbo y distancia. Para ello se han incluido tres funciones nuevas en el gestor de expresiones:

• PointByAngle(): Permite insertar nuevos puntos de la geometría mediante un ángulo y una distancia. El ángulo sería antihorario, siendo el origen 0º en dirección este. La fórmula sería:

PointByAngle(geometría, distancia, ángulo)

donde “geometría” sería el punto desde el cual se insertaría la nueva línea (siendo “$p0” el último punto insertado, “$p1” el penúltimo…), “distancia” sería la longitud del segmento en las unidades de la vista, y “ángulo” sería el ángulo en grados sexagesimales. Por ejemplo PointByAngle($p0,10, 10) sería como se muestra a continuación, 10 metros con un ángulo de 10º sobre la horizontal.

Filling a 4-year gap here! Did not find time to post itemized yearly overviews, plus other updates. And that while even more has been happening compared to the past "COVID-years". Will stick to highlights with a promise to add regular updates.

With the release of QGIS 4, the question of the QGIS release cycle is arising again for many users.

Among the most common:

• what is the roadmap?
• how long will this version be maintained?
• is it a stable version?

The official QGIS roadmap page shows the current versions, along with a countdown to the next one.

I have attempted to simplify the QGIS release cycle, which can be unclear if you go too much into detail. Here is my perspective as a core QGIS developer, simplified to present the release cycle in a schematic way.

There are 3 types of QGIS versions:

Last week I had a call with Professor Gavin Hollis who is writing about Shakespeare’s use of maps and coining the term mapp’ry – you can read a bit more about our conversation here. That conversation prompted me to think about Shakespeare’s references to places in his plays and what that might tell me about his understanding of the world at the end of the 16th century. I thought this would be quite simple but of course the devil is in the detail!

Ya está abierta en Uruguay la Convocatoria 2026 de la iniciativa “Geoalfabetización mediante la utilización de Tecnologías de la Información Geográfica (TIGs)”, una propuesta formativa que combina curso y concurso para impulsar el uso educativo de la cartografía digital, la georreferenciación y los Sistemas de Información Geográfica en las aulas.

Una de las tareas que realiza el Departamento de Topografía y Geomática del Ayuntamiento de Albacete es la de imprimir las fichas de las nuevas vías urbanas que se van creando en el municipio, tras la aprobación de su nombre por Pleno. Este trabajo se realiza directamente con las herramientas disponibles en gvSIG Online, desde la Infraestructura de Datos Espaciales del Ayuntamiento de Albacete, que lo facilita considerablemente.

En la última Jornada IDE en la Administración Local se mostró el nuevo visor de gvSIG Online, con multitud de novedades. Una de ellas es la de poder filtrar gráficamente sobre la vista, no solo sobre la tabla. De esa forma, se pueden realizar filtros en función de uno o varios campos, y que se muestren sobre el visor solamente los elementos filtrados.

From 14th - 17th April, I was fortunate to be able to attend GISRUK 2026, at the University of Birmingham. GISRUK is a regular feature in my calendar and it’s a great opportunity to see what is happening in the world of GIS Research, catch-up with old colleagues and make new connections.

For me, this conference was quite application focused, which I really enjoyed. It’s great to see what GIS can do, as well as learning about new methods and techniques.

Ed Parsons kicked-off the conference with a great keynote, talking about how we, as geographers, can make a difference. He got us thinking about what are the real world problems we can solve - a useful reminder that while the research is important, application is important too.

UPDATE 14th May 2026

Thanks to Harry Wood I discovered that 3,000 of the 45,000 pubs in the FHRS dataset had no coordinates and were not showing on my map. Particularly embarrassing was the omission of the Sutton Arms which is a Geomob after event favourite for geobeers. It was relatively simple to rectify this as all but 6 of the missing records had a postcode that could be used to geocode using postcodes.io. Then I had to rerun the count of pubs per constituency, update the pubs per 10k population and rerun the generalisation of the boundaries – easy enough but an hour wasted.

Se você utiliza o QGIS no seu dia a dia, sabe que os plugins são os “superpoderes” que expandem as funcionalidades do software. No entanto, com grandes poderes vêm grandes responsabilidades — e a necessidade de segurança.

Recentemente, a equipe do QGIS anunciou uma atualização vital no blog oficial: o Repositório de Plugins agora conta com ferramentas automáticas de segurança. Vamos entender por que isso é um marco para o nosso ecossistema favorito.

I thought it might be interesting to look at alcohol consumption and production around the world. I expected the data to be pretty easy to find an process – how wrong can you be!

Consumption figures came from the World Health Organization via Our World in Data, which publishes recorded per capita alcohol consumption broken down by beverage type — beer, wine and spirits — for most countries in the world, with data running up to 2020. The WHO figures measure litres of pure alcohol, so Claude converted these to litres of finished drink using standard ABV assumptions (beer 5%, wine 12%, spirits 40%). The total consumption layer uses pure alcohol to allow a fair comparison across drink types.

El espacio no es contexto, es estructura.

Los Sistemas de Información Geográfica (GIS) parecen hoy inseparables de disciplinas como urbanismo, planificación territorial o gestión ambiental. Sin embargo, su presencia en la enseñanza académica es sorprendentemente desigual: omnipresente en geografía, marginal en arquitectura, casi inexistente en sociología, economía o ciencias políticas. Lo paradójico es que el concepto fundacional del GIS no nació de la informática ni de la ingeniería, sino de algo mucho más antiguo y urgente: un epidemiólogo británico tratando de detener una epidemia.

En 1854, Londres sufría un grave brote de cólera. La teoría dominante era clara y científicamente respaldada: la enfermedad se transmitía por el aire —los llamados «miasmas». Pero John Snow, médico con una observación incómoda, sospechaba que la teoría estaba radicalmente equivocada.

I am struggling to come up with an idea for what to map next. A bit of a brain freeze. Have you got an idea? Leave a suggestion in the comments.

Week 15 was my peak week before Quad Rock on May 9. I didn't run a lot, but it was all high quality running.

• 14 hours, 23 minutes all training

• 24.8 miles running

• 6,020 feet D+ running

Tuesday I hiked and ran up and down Green Mountain in Boulder, my first time on that mountain. I went up the steeper east side and down the more runnable west side. The trail is ridiculously steep: in the first mile I gained 1,300 feet of elevation. There's a ladder at one point, that's how steep it is. The second mile has a short runnable section and averages only 19%. I went steadily to the top and ran the downhills of Ranger and Gregory Canyon as fast as I could while sight-reading. Green Mountain is fun, easy to access, and loved almost to death by Boulderites. The Amphitheater and Saddle Rock trails are in sad shape.

We want to share some updates we have made on the QGIS Plugin Repository. In January 2026 we shared QEP 409. The proposal seeks to improve the general working practices with QGIS plugins, adding some optional and some mandatory checks to every plugin that gets published in the QGIS plugin repo. This builds on initial work (see PR) we did to run ‘soft’ checks on every plugin when they are published.

We also ‘back ran’ the new security checks on every existing plugin in the plugin repository (latest versions only) and assigned them a security badge without blocking or removing any plugin from being published.

La versión 2.7 de gvSIG Desktop incluye una nueva herramienta que permite convertir coordenadas entre distintos sistemas de referencia, que facilita por ejemplo el poder buscar coordenadas de puntos que se tienen en un sistema diferente al de la vista desde la propia aplicación, y no tener que acudir a herramientas externas. En el caso de coordenadas geográficas se puede seleccionar formato decimal, o grados, minutos y segundos.

Esta herramienta complementa al capturador de coordenadas, herramienta que ya existía en versiones anteriores de gvSIG Desktop, y con la que se podía obtener las coordenadas de un punto sobre la vista en el sistema de referencia elegido, aunque la vista estuviese en un sistema diferente. Esta herramienta permitía además guardar dichos puntos, para ser utilizados en algunos geoprocesos.

En el siguiente vídeo se muestra el funcionamiento de ambas herramientas:

Se você já trabalha com dados geoespaciais, provavelmente domina análise. Mas deixa eu te provocar:

Você sabe transformar isso em uma solução acessível na web?

Porque existe uma diferença enorme entre:

Gerar mapas
E entregar uma plataforma que outras pessoas realmente usam

E é exatamente aí que entra o WebGIS.

Hoje, quem se destaca não é só quem analisa dados… É quem consegue:

Centralizar informações
Publicar serviços padronizados (OGC)
Criar aplicações acessíveis via navegador
Controlar acesso e usuários
Escalar o uso dos dados

Em outras palavras: sair do desktop e ir para internet.

Agora vem o ponto que trava muita gente:

“Pra fazer isso eu preciso programar?”

Não.

Com as ferramentas certas, você consegue construir um WebGIS completo usando:

GeoServer 3.0-RC is now available, and with it we can celebrate something bigger than a release candidate.

This milestone is the concrete outcome of a successful community crowdfunding campaign.

When we launched the GeoServer 3 crowdfunding initiative in September 2024, the goal was ambitious. GeoServer needed more than incremental maintenance. It needed a full platform modernization, including a new generation user experience, a stronger security foundation, a modern Java stack, improved raster processing, and the engineering effort required to carry those changes across the broader GeoServer ecosystem.

That work is now visible in GeoServer 3.0-RC.

I needed my training to begin to peak in week 14. Quad Rock is in 20 days (at this writing), and I won't get much adaptation to workout loading in the last 13 days. Weeks 14 and 15 would be my last opportunities to get faster and stronger before the race. Fortunately, a return to good health and favorable weather helped make this my best week yet.

• 13 hours, 8 minutes all training

• 42.7 miles running

• 8,550 feet D+ running and treadmill

The first block of my training was dedicated to power and pure speed, The second to intense aerobic efforts. This last block is about going up and down technical mountain trails at my race pace or a bit faster. In practice, I push pretty hard for half of each climb, run the downhills as fast as I can, and otherwise keep it easy, but not slow.

GeoServer 3.0-RC is now available, with downloads for ( bin, war ), along with docs and extensions. We are working with OSGeo for the windows installer download, and will update this post when it is available. Windows users are asked to test out the bin download while we wait. Release available as docker image docker.osgeo.org/geoserver:3.0-RC .

É oficial! É com muita alegria e entusiasmo que confirmo minha participação no FOSS4G 2026 em Hiroshima! 🇯🇵

Para quem não está familiarizado, o FOSS4G é o maior evento do mundo dedicado ao software livre geoespacial. Organizado pela OSGeo, é o lugar onde desenvolvedores, usuários e entusiastas se reúnem para moldar o futuro das geotecnologias.

Antes de falar das apresentações, quero expressar meu profundo agradecimento à comissão organizadora. Sabemos que realizar um evento desta magnitude exige uma dedicação quase sobre-humana. O o trabalho de vocês é fundamental para fortalecer o ecossistema global de software livre geoespacial. Obrigado por tornarem isso possível!

At OPENGIS.ch, we believe that the long-term health of the QGIS ecosystem depends on more than just adding new features. Critical work like bugfixing, code reviews, codebase maintenance, and quality assurance often goes unnoticed, yet it is essential to delivering the stable, reliable software that thousands of organisations depend on every day. That is why we launched the QGIS Sustainability Initiative (#sustainQGIS). For every support contract of more than 10 days, we donate development time to the initiative. In addition, all unused hours at the end of the year of each contract are also donated. This ensures that buying an OPENGIS.ch support contract directly helps enable the long-term, sustainable development of the QGIS and QField ecosystem.

At OPENGIS.ch, we create open-source software.
We are contributors, maintainers, and in the case of QField, the team that builds it.

That comes with a responsibility we take seriously: giving back.

“Give back” is not a slogan. It is our first core value, and the very reason the sustainability initiative exists.

Open-source is a garden. If you eat from it, water it, and keep seeding.

QGIS.org is pleased to announce that we will be using some of the funding that is donated to us by our users and sustaining members to fund a dedicated administrative role for the project.
