El Plano de Toledo del Greco, elaborado con gvSIG, en el Museo del Prado

Hoy he recibido una llamada que me ha emocionado. Era Cesáreo Bas Vivancos, ya jubilado tras muchos años de docencia en la Universidad Miguel Hernández. En las 11as Jornadas Internacionales de gvSIG, realizadas en 2015, presentó el excelente trabajo llevado a cabo para disponer de una nueva edición del plano de Toledo, elaborado por el Greco, digitalizada y que pudiera estar disponible para todo el mundo.

Cesáreo, decía, me llama para contarme que en el Museo del Prado, en la Galería Central del edificio Villanueva se reúnen, por primera vez desde su dispersión, ocho de las nueve obras que el Greco realizó para la iglesia del Monasterio de Santo Domingo el Antiguo de Toledo. Y que ahí está el Plano de Toledo, el elaborado con gvSIG. En el Museo del Prado.

Vom 16. - 18. Mai 2025 haben sich 23 FOSSGIS- und OpenStreetMap-Begeisterte zum Arbeitstreffen im Linuxhotel getroffen.

Das Treffen begann am Freitagabend mit dem traditionellen Pizzaesssen.
Wie auch schon beim vorigen Treffen gab es nach dem Frühstück am Samstag und Sonntag eine kurze Session, in der zu besprechende Themen gesammelt und ein Zeitplan für den Tag erarbeitet wurden. So lief auch dieses Treffen wieder sehr strukturiert und effizent ab.

Diskutiert wurden Themen zur FOSSGIS- und OpenStreetMap-Community wie Öffentlichkeitsarbeit, Präsenz auf Messen, Beitrag von FOSSGIS und OSM zur digitalen Souveränität, Vor- und Nachbereitung der FOSSGIS-Konferenz und vieles mehr. Auch technische Themen kamen nicht zu kurz, so wurde über Möglichkeiten gesprochen, GPS-Korrektursignale über SSRoverDAB+ mittels low-cost-Hardware zu empfangen, was zentimetergenaue Satellitenpostionsdaten für die breite OSM-Community verfügbar machen könnte. Ein weiteres Thema war das Model Context Protocol (MCP), das die Integration von Künstlicher Intelligenz mit externen Tools und Datenquellen ermöglicht. Damit könnten einerseits die OSM-Daten leichter und effizienter genutzt werden. Andererseits könnte das jedoch auch KI-generierte Edits möglich machen, die von denen echter User kaum zu unterscheiden wären. Letzteres könnte tiefgreifende Konsequenzen für die OSM-Community haben, dieses Thema bietet sicher auf zukünftigen Treffen reichlich Diskussionsstoff.

Die Teilnehmenden schauen auf ein angenehmes, produktives Treffen mit großartigen Teilnehmer:innen, die nicht nur tolle inhaltlche Beiträge lieferten, sondern auch bei der Organisation kräftig mit anpackten, zurück. Besonderer Dank gilt Katja, Marc und Jochen für die hervorragende Moderation der Sessions und dem Versorgungsteam für die Verköstigung. Und ohne die fantastische Unterstützung des Linuxhotels wäre auch dieses Treffen nicht möglich gewesen.

Die umfangreichen Ergebnisse der Besprechungen sind auf der Wiki-Seite des Treffens festgehalten. Selbstvertsändlich konnten Teilnehmehmende auch bei diesem Treffen weiter an ihren Projekten arbeiten: https://www.fossgis.de/wiki/FOSSGIS_OSM_Communitytreffen_2025_Nummer_23#Bericht/Ergebnisse

Gregory said “The contour letters in Cape Town – I don’t know if that counts as a map, but each one was a specific local mountain” Yes, that definitely counts!

Neat use of contours?

Thirteen and fourteen were another two weeks of tempo-focused training with minimal running. The 13th included a long day of hiking and trail maintenance work. Lots of time on my feet in the company of other trail runners. It was a bit like a trail race in that way, but much easier.

• 4.5 miles running

• 13 hours, 51 minutes all training

• 289 ft D+ running

Week 14 was a planned rest week, and somewhat lighter.

• 4.5 miles running

• 8 hours, 8 minutes all training

• 361 ft D+ running

Even though my left Achilles tendon won't let me run much, and working out indoors isn't very effective or satisfying, I've been managing to increase my training volume by doubling up on workouts. Both weeks were similarly structured. I biked and did a heated "power" Vinyasa yoga class at the gym on Monday, with some hot tubbing afterwards. Wednesdays I did a short tempo run outside at Pineridge Open Space and then went back into the gym for another tempo session on an elliptical trainer and some sets of back squats or box step-ups and jumps. This was my biggest day each week. Thursdays I paired an hour long lunchtime bike ride with an evening Pool HIIT (high intensity interval training) class and a sauna session. Fridays I went back to the gym for an hour long tempo workout on the elliptical and more soaking of my lower legs. This all adds up to 75 minutes of effort at 8-8.5 out of 10 RPE (rate of perceived exertion). I'd like to be at 90 minutes, but I'm doing the best I can.

I'm going to see my doctor tomorrow and inquire about an intervention for my chronically inflamed Achilles. The steroids I took last fall to treat my pinched femoral nerve and associated back pain also cured, as a side effect, the last nagging irritation in my right Achilles (that flared in July 2024 and ended my running plans for the year). I don't believe my left is seriously injured, and that it can bear more stress if I can get the inflammation down. I may be referred to a specialist about this.

The other specialists I'm seeing soon are the folks at a local eye wear shop to get sporty, photochromic prescription sunglasses. I tried and failed with contact lens in April. I can get them on my eyes easily enough, but I can't get them out by myself for the same reason that I have always struggled with opening produce bags at the grocery store: faint fingerprints. I just can't get a grip on the contacts. If the local shop doesn't have what I need, I may try sending my prescription to Julbo, the French company. I've been considering the company's reactive glasses for a while, and Bryon Powell's recommendation here is convincing.

I'll wrap up this longish recap with more about the trail work day. There is no trail running without trails (that would be fell running), and trails need regular care and maintenance. If trails are eroded, not passable, or persistently muddy, people will route around them and create new social trails. This leads to trail "braiding" and degradation of the natural landscape and ecosystem damage. Here in arid Colorado, vegetation grows slowly, and the landscape recovers slowly from injury. In Lory State Park, the situation is compounded by soils that turn into peanut butter when saturated.

Gnar Runners, the local running events org that manages Quad Rock and other races in Lory State Park, organizes a trail work day at Lory each spring and fall. I've been participating in the spring one for the last five years. As more and more trail races require proof of trail work or other volunteering, the number have grown. This year there were 24 of us. Ten were meeting requirements of the upcoming High Lonesome event in the Sawatch Range. The Bear 100 also requires eight hours of trail work or volunteering. A lot of us would do this even if it was not required. It feels right and good to take care of a place that you enjoy and depend on.

It's also fun to make new friends and share running stories and plans. Brad Bishop and Nick Clark, the Gnar team, have directed and run more ultra marathons than I ever will and I always learn something new from them. Nick's a legend of the sport, after all. It's like I'm cleaning trail drains with Larry Bird. And some years, like this one, elite contemporary racers come out to work alongside the mere mortals. It'll be extra fun to follow the Western States Endurance Run this year, knowing somebody who is aiming for the podium.

I’ve been working around sea ice for close to two decades on and off – and have had the privilege of being up close and personal with floating chunks of frozen ocean in both the Arctic and Antarctic. An enduring geophysical question about sea ice is “how much ice floats on the ocean?” Sea ice,… Read More »Identifying deformed sea ice using geomorphons

Last year Gregory Marler (aka on social media as Living with Dragons) went to South Africa, he found lots of mappy stuff to share with us, so good that I thought `I would make a short series of his pics.

This one is a tactile map at the top of Table Mountain https://www.openstreetmap.org/node/287085527#map=19/-33.958275/18.403714 (Greg is a long-time contributor to OSM and added links to all of the locations)

Lose Hill is situated in the Peak District on a nice trail from Mam Tor. This hill offers a 360-degree landscape.

Reinder spotted this book cover, the title is “The Signal to Surrender”.

Reinder explained “It’s not a perfect copy – but still attractive though, according to me. The design is by none other than the great Dutch graphic artist Dick Bruna. https://en.m.wikipedia.org/wiki/Dick_Bruna

Personally I think the book title is a little too stark and something softer would have worked better but the map relief style is excellent

Our followers will recognise the view from a few days ago with my Hip Flask. Now here is the OS Picnic Blanket standing on a proper map in the wilderness of the Peak District.

We are thrilled to announce that the GeoServer 3 crowdfunding campaign has not only met but exceeded its funding target! This remarkable achievement is a testament to the unwavering support and commit...

GeoServer Installation and Upgrade Guide

In this session, we will install GeoServer on Windows using the Web Archive installation method and upgrade to a new version, while retaining existing data.

If you want to access the complete tutorial, click on the link.

Introduction

GeoServer is a versatile, Java-based application compatible with various operating systems, provided a suitable Java Virtual Machine (JVM) is available. The latest versions of GeoServer have been tested with both Oracle JRE and OpenJDK.

The GeoServer WAR file is a platform-independent web archive designed for deployment on application servers. Apache Tomcat is the recommended servlet container due to its robust integration capabilities and comprehensive documentation. This setup allows multiple web applications to run concurrently, enabling GeoServer to operate alongside other Java-based services, enhancing server versatility.

Note. This guide outlines the installation of GeoServer 2.25.x using Java 17 and Apache Tomcat 9, followed by upgrade instructions. To ensure you have the latest release, please visit this link and avoid using older versions of GeoServer.

Preparing for Installation

Before proceeding, follow the steps below:

• Backup the existing GeoServer folder (if upgrading).

  The folder webapps/geoserver/data is the data directory containing your configuration settings you wish to preserve.

  The folder webapps/geoserver/WEB-INF/lib contains the deployed GeoServer web application, along with an extensions you have manually installed.

• Check the Modules tab under the Server Status page to see all installed extensions.
• Uninstall previous versions of Java and Apache Tomcat.

Installing Java Development Kit (JDK)

To download JDK 17, navigate to adoptium.net and select:

• Operating System: Windows
• Architecture: x64
• Package Type: JDK
• Version: 17-LTS

Download the .msi file and run it as an administrator. During installation, accept default settings and complete the setup.

Installing Apache Tomcat

To download and install Apache Tomcat software, navigate to tomcat.apache.org and select Tomcat 9 from the Download section.

Choose the 32-bit/64-bit Windows Service Installer and run it as an administrator.

During setup:

• Configure the ports (default recommended).
• Set a secure username and password for administration (avoiding common defaults like admin or tomcat).
• The installer should auto-detect the installed JDK; if not, the user manually selects the Java installation path.

To configure JVM memory allocation, navigate to C:\Program Files\Apache Software Foundation\Tomcat 9.0\bin and run Tomcat9w.exe as an administrator.

In the Java tab, the user sets:

• Initial Memory Pool: 512 MB
• Maximum Memory Pool: 1024 MB

• Java Options: As required for running on Java 17.

       --add-exports=java.desktop/sun.awt.image=ALL-UNNAMED
       --add-opens=java.base/java.lang=ALL-UNNAMED
       --add-opens=java.base/java.util=ALL-UNNAMED
       --add-opens=java.base/java.lang.reflect=ALL-UNNAMED
       --add-opens=java.base/java.text=ALL-UNNAMED
       --add-opens=java.desktop/java.awt.font=ALL-UNNAMED
       --add-opens=java.desktop/sun.awt.image=ALL-UNNAMED
       --add-opens=java.naming/com.sun.jndi.ldap=ALL-UNNAMED
       --add-opens=java.desktop/sun.java2d.pipe=ALL-UNNAMED
  

Switch to the General tab, and set Startup Type to Automatic, and start the Tomcat service.

Deploying GeoServer

Download the latest GeoServer WAR file from geoserver.org.

Extract the .war file and copy it to C:\Program Files\Apache Software Foundation\Tomcat 9.0\webapps.

To start GeoServer:

• Navigate http://localhost:8080/manager.
• Login with the Tomcat credentials.
• Click Start next to the GeoServer application.

The user accesses GeoServer at http://localhost:8080/geoserver and logs in using the default credentials:

• Username: admin
• Password: geoserver

Upgrading GeoServer

Stop GeoServer via the Tomcat Manager App, then replace the existing webapps/geoserver/data directory with the one from your backup.

Reinstall any compatible extensions for the new version, and restart GeoServer and verifies functionality.

Im Oktober wird QGIS 4.0 veröffentlicht. Wir haben uns bereits im Vorfeld umgeschaut und uns damit beschäftigt, was die neue Version für QGIS-Plugins bedeutet und geben Ihnen wertvolle Tipps.

The FOSS4G Europe conference is more than a conference: It's a reflection of a growing movement toward transparency, collaboration, and long-term sustainability in geospatial technology. We’re proud to be long-standing contributors.

Elizabeth spotted this in Delhi Airport

Our friend and top contributor, Reinder, sent us this. He said “. on a map of Belgium (in French) from 1965 … – isn’t it a beauty?” The answer is yes, beautiful, just beautiful! I don’t know what it is about this design that makes it feel so good.

The PostGIS Team is pleased to release PostGIS 3.6.0alpha1! Best Served with PostgreSQL 18 Beta1 and GEOS 3.13.1.

This release is an alpha of a major release, it includes bug fixes since PostGIS 3.5.3 and new features.

The latest releases of MovingPandas and Trajectools come with many “under the hood” changes that aim to make your movement analytics faster:

1. Instead of immediately creating a GeoPandas GeoDataFrame and populating the geometry column with Point objects, MovingPandas now has “lazy geometry column creation” that holds off on this operation until / if the geometries are actually needed. This way, for many operations, no geometry objects have to be generated at all.
2. MovingPandas TrajectorySplitters now support parallel processing and Trajectools uses parallel processing whenever available (e.g. for adding speed & direction metrics, detecting stops, splitting trajectories).
3. When a minimum length is specified for trajectories, MovingPandas now avoids computing the total trajectory length and, instead, immediately stops once the threshold value has been reached (“early skip”).
4. Trajectools now offers the option to skip computation of movement metrics (speed & direction). This way, we can skip unnecessary computations and leverage the lazy geometry column creation, wherever applicable.

Let’s have a look at some example performance measurements!

Example 1: MovingPandas ValueChangeSplitter

The ValueChangeSplitter splits trajectories when it detects a value change in the specified column. This is useful, for example, to split up public trajectories that contain a “next_stop” column.

The following graph shows ValueChangeSplitter runtimes for different minimum trajectory length settings (from 0 to 1km, 100km, and 10,000km):

We see that the new, lazy geometry column initialization outperforms the old original code in all cases (e.g. 57% runtime reduction for 1km), except for the worst-case scenario, when the original implementation discards all trajectories as too short right from the start. (For most use cases, min_length will be set to rather small values to avoid creation of undesired short trajectory fragments, similar to sliver polygons in classic geometry operations.)

Additionally, we can engage multiprocessing by setting the n_processes parameter, e.g. to the number of CPUs to achieve further speedup:

Example 2: Trajectools

By applying all above-mentioned speedup techniques, Trajectools is now considerably faster. For example, the following runtime reductions can be achieved by deactivating the “Add movement metrics (speed, direction)” option in the algorithm dialog:

• Create trajectories: 62%
• Spatiotemporal generalization (TDTR): 78%
• Temporal generalization: 81%
• Split trajectories at stops: 53%

I have also updated the default trajectory points output style. It now uses a graduated renderer to visualize the speed values (if they have been calculated) instead of the previously used data-defined override. This makes the style faster to customize and provides a user-friendly legend:

For more infos, have a look at:

• MovingPandas 0.22 release notes
• Trajectools 2.6 release notes

Enjoy the latest performance increases!

These amazing globe sculptural works were spotted by Reinder near the AFAS theatre in Leusden. He described them to me as “quite remarkable – and gigantic!” I can only agree, awesome.

The scale of these things is just amazing!

The PostGIS Team is pleased to release PostGIS 3.5.3.

This version requires PostgreSQL 12 - 18beta1, GEOS 3.8 or higher, and Proj 6.1+. To take advantage of all features, GEOS 3.12+ is needed. SFCGAL 1.4+ is needed to enable postgis_sfcgal support. To take advantage of all SFCGAL features, SFCGAL 1.5+ is needed.

El próximo 11 de junio, la Asociación gvSIG participará en el evento “Del dato al impacto: cómo la inteligencia colectiva y la tecnología protegen vidas ante fenómenos meteorológicos adversos”, organizado por Innotransfer y el Parque Científico de la Universidad Miguel Hernández (UMH).

Participaremos como parte del panel de expertos que abordará el papel de la tecnología y la inteligencia colectiva en la prevención, monitorización y respuesta ante eventos meteorológicos extremos como inundaciones, lluvias torrenciales o tormentas intensas, cada vez más frecuentes en el contexto del cambio climático.

Desde gvSIG, venimos trabajando desde hace años en soluciones abiertas, interoperables y colaborativas que permiten integrar y analizar datos geoespaciales en tiempo real para mejorar la toma de decisiones en contextos de emergencia. Nuestra experiencia en proyectos relacionados con la gestión del riesgo y protección civil será uno de los focos de nuestra intervención.

Este evento se enmarca en el programa Innotransfer, una iniciativa que promueve el intercambio de conocimiento entre el mundo académico, las empresas y las administraciones públicas.

¿Por qué es importante?

Los fenómenos meteorológicos adversos no solo ponen en riesgo infraestructuras, sino también vidas humanas y ecosistemas completos. Apostar por soluciones tecnológicas y modelos de colaboración eficaces no es una opción: es una necesidad.

Invitamos a quienes trabajan en el ámbito de la gestión territorial, emergencias, medio ambiente o administración pública, a asistir o seguir el evento. Es una oportunidad para compartir visiones, generar sinergias y seguir construyendo un futuro más resiliente desde la ciencia abierta y la tecnología libre.

David Sherrren sent me this pic of the Strand Mural Map

“Attached is the Strand Map Mural, named after the junction it faces in Southsea, Hampshire. In 2020 its creator, Mark Lewis, asked Guinness World Records to recognise this depiction of Portsmouth as the world’s only ever-changing mural. Business premises and vans, for example, can be added for a fee.”

En plena era digital, donde la información es uno de los activos más valiosos, los ayuntamientos manejan a diario una enorme cantidad de datos vinculados al territorio: desde catastro y urbanismo hasta patrimonio, medio ambiente o movilidad. Sin embargo, muchas veces esta información está dispersa, duplicada o difícil de compartir entre departamentos. Aquí es donde entra en juego la Infraestructura de Datos Espaciales (IDE).

¿Qué es una IDE y por qué es clave?

Una IDE es una plataforma tecnológica que permite gestionar, visualizar y compartir datos espaciales (geográficos) de manera eficiente, interoperable y abierta. Utiliza estándares internacionales que garantizan la compatibilidad con otros sistemas y facilita el acceso tanto interno (entre áreas municipales) como externo (hacia la ciudadanía).

Más del 80% de la información que maneja una administración local tiene una componente geográfica. Desde una incidencia en la vía pública hasta un expediente urbanístico, todo tiene una ubicación. La IDE permite “conocer para gestionar”: visualizar esa información sobre un mapa facilita la toma de decisiones, mejora la transparencia y optimiza los recursos públicos.

Beneficios reales para los municipios

Implementar una IDE como gvSIG Online permite a los ayuntamientos:

• Disponer de una base cartográfica única que evite duplicidades y errores.
• Geolocalizar información como inventarios, censos o incidencias urbanas.
• Compartir datos entre departamentos, mejorando la eficiencia en la gestión.
• Crear visores de mapas personalizados accesibles para los ciudadanos, fomentando la participación y el gobierno abierto.
• Cumplir con normativas de datos abiertos, transparencia y reutilización (como la Directiva INSPIRE o la Ley 19/2013).

¿Qué se puede gestionar con una IDE?

Casi cualquier área municipal puede beneficiarse de una IDE:

• Urbanismo y catastro: gestión de expedientes, seguimiento de obras, cambios temporales.
• Turismo: mapas interactivos con rutas, eventos y patrimonio cultural.
• Medio ambiente y residuos: seguimiento de zonas verdes, contenedores, puntos limpios.
• Movilidad: red de transporte público, aparcamientos, carriles bici.
• Inventario municipal: alumbrado, bancos, señalización, fuentes…
• Emergencias y protección civil: localización de hidrantes, edificios críticos, rutas de evacuación.

gvSIG Online: tecnología libre y adaptable

Una de las soluciones más completas para IDE municipales es gvSIG Online, desarrollada bajo software libre. Esto significa:

• Sin costes de licencias, lo que reduce barreras económicas.
• Escalable y adaptable a las necesidades del municipio.
• Posibilidad de implantación como servicio (SaaS) o en los servidores propios del ayuntamiento (On-Premise).
• Integración con sensores, gestores de expedientes, portales de datos abiertos, padrón, etc.

Conclusión

Contar con una IDE no es solo una cuestión tecnológica, sino estratégica. Permite a los ayuntamientos avanzar hacia una gestión más eficiente, transparente y participativa. Es una herramienta clave para construir ciudades inteligentes y resilientes, donde la información espacial esté al servicio del bienestar colectivo.

Si tu municipio aún no cuenta con una IDE, quizá sea momento de dar el paso.
