Fernando Quadro: Publicando rasters com COG + S3/MinIO + GeoServer
Quando trabalhamos com ortomosaicos ou rasters muito grandes, um dos principais desafios é como armazenar e publicar esses dados com boa performance, sem sobrecarregar o servidor GIS.
Uma arquitetura moderna que vem sendo cada vez mais utilizada é baseada em:
- Cloud Optimized GeoTIFF (COG)
- MinIO ou Google Cloud Storage ou Amazon S3 (Object Storage)
- GeoServer
ul>
Essa combinação permite que o GeoServer leia diretamente rasters armazenados em object storage, sem precisar copiá-los para o servidor.
Neste post vou mostrar um passo a passo simples e prático para implementar essa arquitetura:
O ponto principal aqui é que o GeoServer não precisa armazenar o raster localmente. Ele apenas acessa o arquivo COG diretamente no storage.

gvSIG Team: Some notes on the Roadmap to accelerate digital sovereignty
In recent days, the Roadmap to Accelerate Digital Sovereignty in Spain has been presented, a document that reflects something that has been becoming increasingly clear for some time now: digital sovereignty has ceased to be an abstract concept and has become a strategic issue. We are no longer talking only about innovation, but about decision-making capacity, resilience, technological autonomy, and control over critical infrastructures. Technological dependence is a structural vulnerability.

gvSIG Team: Novedades gvSIG Desktop 2.7: Swipe o cortinilla para comparativa de cartografía
La nueva versión gvSIG Desktop 2.7 incluye la herramienta de Swipe o Cortinilla. Con esta herramienta es posible comparar cartografía diferente de forma sencilla, como por ejemplo dos ortofotos de años diferentes.
El funcionamiento de esta herramienta es a partir de dos vistas diferentes, donde en cada una de ellas se deberá tener una de las capas a comparar. El usuario podrá elegir la opción de realizar cortinilla de forma vertical u horizontal, y se aplicará sobre las capas que se tenga visibles en ese momento en las dos vistas. Una vez seleccionadas ya solo deberá desplazar la barra central horizontalmente o verticalmente para poder ver las diferencias.

Martin Davis: Fast Hausdorff Distance and isFullyWithinDistance in JTS
My previous blog post reviewed the concept of the Hausdorff distance (which more descriptively could be called farthest distance.) Despite its usefulness in matching geometric data, there are surprisingly few open-source implementations, and seemingly no efficient ones for linear and polygonal data. This even includes CGAL and GRASS, which are usually reliable for provising a wide spectrum of geospatial operations.

Ebbene sì, cara lettrice, anche nel 2025 ho letto, ho visto, ho guardato, ho ascoltato, ho fatto cose sia stando fermo dove ero sia muovendomi. Da un certo punto di vista tutto quello che segue in questo articolo è nullo perché il 2025 è stato l’anno di un blando ma importante risveglio dal torpore e sono andato alcune (o tante, punti di vista) volte in piazza a mettere il mio corpo per il popolo di Gaza. Ma da un altro punto di vista tutto quello che segue è esattamente quello che bisogna fare per non vendere le nostre vite allo stesso sistema che ci divora, ci rende complici. Nulla di tutto questo è intrattenimento, tutto è sbattimento, tutto è amore, tutto è rabbia.

Fernando Quadro: Como instalar plugins do GeoServer no GeoNode 5
Prezado leitor,
Se você instalou o GeoNode 5 via Docker (GeoNode Project) e precisa adicionar um plugin que não vem na instalação padrão do GeoServer, este guia vai te mostrar como fazer isso da maneira correta e reproduzível.
No meu caso, estou utilizando:
- GeoNode 5.0.0
- GeoServer 2.27.3
O objetivo é instalar o plugin Resource Browser Tool, que permite navegar e gerenciar arquivos do GeoServer diretamente pela interface web.
1. Baixar o plugin:
O plugin precisa ser exatamente da mesma versão do GeoServer. Como estou usando a versão 2.27.3, o plugin também deve ser 2.27.3.

Martin Davis: The Hausdorff Distance Challenge
The Hausdorff Distance is a useful spatial function which can appear slightly mysterious. Partly this is due to the name. It honours Felix Hausdorff, one of the founding fathers of topology, and a polymath who was creative in music and literature as well as mathematics.

Sean Gillies: Quad Rock training week six
I ran four times, did one elliptical recovery spin on cold day, a recovery bike ride, one weight-lifting session, one yoga class, and the daily mobility and core workout six times.
12 hours, 56 minutes all training
27.2 miles running
6,100 ft D+ running *
I put an asterisk by the elevation gain, because two-thirds of this was on a treadmill during interval workouts. There were no matching descents, and that's the toughest part of running in the mountains.
Running uphill is hard, but also relatively low impact. That's a win-win for my training. I'm doing almost all of my intense running right now at 10-12%, on a treadmill or steep road. In week six, I did 27 minutes of hard 30/30 running. Running on an 8% incline at an 11 minutes per mile pace felt more fun than going slower on a steeper setting. I'll do more of this.

GIScussions: Britain and Ireland’s Flora – inspired by The Rolling Stones
“You can’t always get what you want
But if you try sometimes, well, you might find
You get what you need” (Rolling Stones, You Can’t Always Get What You Want, Album: Let it Bleed, 1969)
I had an idea for a map – where did all of the non native plants in Britain come from? I thought there might be something interesting there if I could find the data and map it.
I called up my new friend Claude and asked for some help with the data “is there a dataset that shows common flower and shrub species found in great britain and their country of origin (possibly with some historical narrative of how they arrived in the uk)?” That took me to the Royal Botanical Gardens Kew’s “BIFloraExplorer” with over 3000 species in Britain and the Botanical Society of Britain and Ireland’s “Plant Atlas 2020” – loads of time saved, I had some authoritative and relevant data in minutes.

Sean Gillies: Quad Rock training week five
Unusually mild weather helped make week five productive. I can feel the benefits as I write this, a week later.
11 hours, 37 minutes all training
19.3 miles running
1,890 ft D+ running
Tuesday I did hill sprints on the "Wallenberg Wall" in my neighborhood. My cadence has increased, and I was a second faster on average. 23 seconds instead of 24. Getting faster is one of my goals, and I'm making measurable progress.

Ecodiv.earth: Counting NDFF records
The NDFF (Nationale Databank Flora & Fauna) holds over 200 million verified observations of plant and animal species from the Netherlands. These data are contributed by volunteers and professionals from hundreds of organizations. Together they contain a wealth of information about the occurrence of plant and animal species in the Netherlands. Since 2025, the database is accessible to everyone free of charge. That means that one can download all data for 5 × 5 km grid cells (certain restrictions apply).
Observations are provided as polygons. This post provides an example of how to quickly create summary raster maps showing the total number of observed species. Non-native species are excluded to focus on native biodiversity patterns. Moreover, each record is treated as a single observations regardless of the reported number of individuals.

gvSIG Team: gvSIG as European Digital Infrastructure
What does it mean to speak about European digital infrastructure? It means:
- Use of open standards (such as those promoted by the Open Geospatial Consortium).
- Compliance with regulatory frameworks such as INSPIRE.
- A real possibility of self-hosting.
- Independence from unilateral changes in licenses or terms of use.
- The ability to audit, evolve, and adapt the system over the long term.
Europe has clearly defined its commitment to the digital commons and technological sovereignty.
But that strategy is not materialized through declarations. It is materialized through real infrastructures.
gvSIG Team: gvSIG como infraestructura digital europea
¿Qué significa hablar de infraestructura digital europea? Significa:
- Uso de estándares abiertos (como los promovidos por el Open Geospatial Consortium).
- Cumplimiento de marcos normativos como la directiva INSPIRE.
- Posibilidad real de autohospedaje.
- Independencia frente a cambios unilaterales de licencias o condiciones de uso.
- Capacidad de auditar, evolucionar y adaptar el sistema a largo plazo.
Europa ha definido claramente su apuesta por el bien común digital y la soberanía tecnológica. Pero esa estrategia no se concreta en declaraciones. Se concreta en infraestructuras reales.

GIScussions: Does vibe coding democratise software tools?
No maps in this post!
I mentor a couple of people and I was about to start a new project this week. I was going to knock up a Google Sheet or Doc to track goals, talks and meetings and share with the mentee and my co-mentor. It occurred to me that I could vibe code an app to track the mentee’s progress and to provide structure to our regular meetings.
With a lot of help from Claude I’ve got something running that does that for a few mentors and mentees, it runs on desktop and mobile and quite a lot of the input is voice to text which is particularly useful in mobile. It took about 3 hours, to build test and deploy.
I am sure that I’ll find some problems or feature gaps in the future but that doesn’t matter in my use case. I don’t plan to build this into a business or to scale it up to thousands of users it’s just a tool that makes record keeping for me and my mentees easier.

OPENGIS.ch: QField search and routing plugins updates
Throughout the first month of 2026, our ninjas added a nifty set of improvements to three useful plugins that we love: the GeoMapFish Search, OpenStreetMap Nominatim Search, and OSRM Routing plugins. These plugins all provide genuinely useful functionalities as well as being great showcases of how easy it is to integrate QField with online REST endpoints.
All three plugins have been updated to ship with useful endpoint presets out of the box, and users also have the option to configure their own custom endpoints for more flexibility. To configure endpoints, open QField’s settings panel, navigate to the plugin manager, and click the settings button next to the desired plugin.

gvSIG Team: Novedades gvSIG Desktop 2.7: Nueva Calculadora de campos
La nueva versión 2.7 de gvSIG Desktop incluye una nueva calculadora de campos, cuyas principales ventajas son, por un lado, que se pueden rellenar varios campos a la vez, y por otro, que ha mejorado significativamente el rendimiento cuando se pretenden rellenar muchos registros a la vez, al no cargarse en memoria todos ellos sino por bloques.
La nueva calculadora se basa en la herramienta de actualizar tabla que se había incluido en la versión anterior, donde se había mejorado la parte de rellenado de registros. Ahora dispone de una pestaña “Opciones” donde se puede seleccionar el número de registros en los que se quiere que termine edición y reinicie. De esa forma no carga todos los datos en memoria y no bloquea el equipo, evitando así también posibles pérdidas de datos.

Sean Gillies: Quad Rock training week four
The numbers went up in week four.
13 hours, 23 minutes all training
30.2 miles running
4,108 ft D+ running
More important is that I got in my power-building workouts. A big session of back squats and single-leg step-downs, among other exercises, at the gym on Tuesday after seeing my physical therapist. A session of hill sprints on Thursday after an easy run with a friend at Pineridge Open Space.
Saturday I went on another Quad Rock training run with a big crowd on an extraordinarily warm day. I'm glad I wore shorts and brought a third bottle of water. There were some icy spots early, but they'd melted on the return leg. I paid the price for going out too fast with some cramping at the finish, and struggled with knee stiffness, but mostly had a great morning.

gvSIG Team: Cuando el software libre es la opción conservadora
En muchas ocasiones, hablar de software libre o de código abierto en proyectos públicos se asocia a innovación. Y aunque es cierto que el acceso al conocimiento permite innovar de forma más eficiente en muchos ámbitos, también suele interpretarse como una apuesta por soluciones alternativas o incluso de riesgo.
Si nunca lo fue, hoy todavía menos: esa lectura ya no encaja con la realidad.
Cada vez más, el verdadero riesgo no está en el software libre. Está en la dependencia.
