Time Traveling with OHM

Today I've been playing with OpenHistoricalMap and exploring how it can be used to create a map that visualizes how a country's borders have changed over time.History is rarely static, but few nations illustrate the fluidity of borders quite like Poland. Over the last two centuries, the Polish state has expanded, contracted, and even physically shifted hundreds of miles across the European

GIScussions: Shakespeare’s World – I thought this would be simple but …

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!

gvSIG Team: Creación de hojas de campo de vías urbanas con gvSIG Online

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.

gvSIG Team: Novedades gvSIG Desktop 2.7: Herramienta para creación de cajetines personalizados en el mapa

La versión 2.7 de gvSIG Desktop incluye una mejora muy interesante en los mapas, que es la de poder personalizar los cajetines. Hasta las versiones anteriores, solo permitía insertar un cajetín con un número de filas y de columnas concretas, donde todas tenían el mismo tamaño, por lo que la única forma de crear cajetines personalizados era creando los rectángulos de forma individual, que hacía que fuese más complejo.

Con la nueva herramienta, una vez se inserta el cajetín con un número de filas y de columnas, existe la opción de editar dicho cajetín, de forma que se pueden combinar celdas, o dividirlas horizontal o verticalmente, permitiendo así tener celdas de diferentes tamaños para poder insertar la escala, el título, el logo de nuestra entidad, nuestra firma, etc.

Nick Bearman: GISRUK 2026: GIS that makes a difference

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.

GIScussions: Nearest Pint, Pub Density Map

GIScussions: Nearest Pint, Pub Density Map

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.

Learning: Even if your dataset is too large to thoroughly inspect, 5 minutes spent scrolling through it, running a couple of sorts and doing some kind of sanity check is time well spent.

GIScussions: Alcohol Consumption & Production – you’d think the data would be easy?

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.

GRASS GIS: GRASS 8.5.0 released

Two years in the making GRASS 8.5.0 is here. This feature release contains more than 2570 changes, the result of two years of focused work by the GRASS community. We deliberately postponed what would have been a 2025 release so that several interlocking pieces could land together: a new Python API, JSON output across dozens of tools, and a complete rewrite of the documentation. These changes are more useful together than they would have been in sequence, and they took time to do well.

Week 16 is over. It's six days to Quad Rock.

  • 10 hours, 11 minutes all training

I did a small set of hard running intervals, some steady running, and one last hilly run on the Quad Rock course with a friend on Friday. We pushed the pace on the upper half of the first climb, going up Towers Trail, and I was just a few seconds off my personal bests on those segments. 10/10 effort on Saturday won't be sustainable, but it was fun and a useful check on my fitness before the race.

Sean Gillies: Kyle Kingsbury's bullshit about bullshit machines

You've probably seen links to "The Future of Everything is Lies, I Guess" already. I've just finished the last installment. This is an excellent series of posts with many references. If we meet to talk about the industry, I'm almost certainly going to ask if you've read it.

This is bullshit about bullshit machines, and I mean it. It is neither balanced nor complete: others have covered ecological and intellectual property issues better than I could, and there is no shortage of boosterism online. Instead, I am trying to fill in the negative spaces in the discourse. “AI” is also a fractal territory; there are many places where I flatten complex stories in service of pithy polemic. I am not trying to make nuanced, accurate predictions, but to trace the potential risks and benefits at play.

geomatico: Los mapas que se ignoran

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.

Un plano que cambió la forma de entender la ciudad

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.

  • 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.

QGIS Blog: Plugin Repository Security Enhancements

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.

GeoServer Team: GeoServer 3.0-RC, a crowdfunded success story

GeoServer Team: GeoServer 3.0-RC, a crowdfunded success story

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.

Sean Gillies: Quad Rock training week 14

Sean Gillies: Quad Rock training week 14

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.

Sean Gillies: Quad Rock training week 13

Week 13 started out pretty strong. I returned to my favorite Monday evening yoga class, did a fun run with strides at Pineridge on Tuesday, and then a hard running interval workout on Towers Trail in Horsetooth Open Space on Wednesday. Thursday I had cold symptoms again and shifted to dog walking and bike riding for the rest of the week. The running numbers for the week are nothing much.

  • 11 hours, 35 minutes all training

  • 14.6 miles running

  • 2,041 feet D+ running

By Saturday afternoon I felt much better, which gave me hope for a solid week 14.

OPENGIS.ch: QGIS Sustainability Initiative – Annual Report

What is the QGIS Sustainability Initiative?

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.

QGIS España: ¿QGIS Camp España 2026? ¿Madrid o Granada?

Desde la Asociación QGIS España queremos compartir con la comunidad una reflexión abierta y, sobre todo, lanzar una consulta clave para la toma de decisiones de este año.

Como ya sabéis, en 2026 no se celebrarán las Jornadas de SIG Libre de Girona, un evento que durante años ha sido el principal punto de encuentro de la comunidad SIG Libre y que, además, servía de marco para la celebración de la QGIS Camp España, donde personas asociadas y usuarias de QGIS nos reuníamos para compartir experiencias, debatir sobre la herramienta y sobre el propio rumbo de la Asociación.

Creemos que la comunidad no debería quedarse sin su encuentro anual, y por ello desde la Asociación estamos valorando la posibilidad de celebrar la QGIS Camp España en 2026, manteniendo el espíritu participativo que siempre ha caracterizado a este espacio.

OPENGIS.ch: Sustainability initiative: what is it and why we do it?

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.

Legible Rude Places Map

This morning I was browsing Gary Gale's Vaguely Rude Places map and realised that thanks to my deteriorating eye-sight I could no longer read all the hilariously rude place-names around the world. Instead of simply diving into my browser settings and magnifying the page I decided it would be far more satisfying to create my own map. Luckily for me Gary has provided links to easily download the

By utilizing a vibrant, data-driven color palette, he created a visual standard that not only captured the public’s imagination but also inspired a

Jackie Ng: New plans and stuff

So after finally getting MapGuide Open Source 4.0 out the door, I took a self-imposed hiatus from all things mapping/GIS related for several months, permanently moved from Windows to Linux as my daily driver OS just in time before the end of Windows 10 support, and also to mentally recharge and savor the relief of having this major burden (of releasing MGOS 4.0) being finally lifted off of my back.

I now return with a renewed vigor and some rough roadmaps for things going forward in MapGuide and my other various projects. Part of that renewed vigor is due to the advent of ...

NCRM: Generative AI Tools for Quantitative Research

David Bann and Liam Wright have put together a great guide to Generative AI Tools for Quantitative Research on the NCRM resources site. This is a great overview of what Generative AI is, how it works and all of the potential different models available, both commercial and open source, as well as how to run some models locally rather than relying on the cloud.

They are also very focused on the practical elements of how to actually use the tools in your work, discussing the different approaches as well as highlighting the importance of making sure you do not share sensitive data with cloud services.

They also have a great selection of videos for setting up both cloud based and local LLMs for working with Stata and R scripts in a number of tools including VS Code:

Sean Gillies: Quad Rock training week 12

In week 12, I started to get things back on track after being sick. I ran five days, biked one day, and took Saturday off to take my family to a Nuggets game in Denver.

  • 12 hours, 9 minutes all training

  • 34.8 miles running

  • 5,800 ft D+ running (and treadmill)

My energy level was low to mid until Friday, when I rallied for a good interval workout on a 12% incline treadmill indoors and a sauna session after. My fitness didn't advance much in week ten, but I didn't lose a step. According to the machine, I went "up" beyond any of the Quad Rock climbs, and at a pace that I'd love to hit on race day.

GIScussions: Critical Minerals – The Global Supply Chain

Listening to the news about the impact of the current war and the closure of the Strait of Hormuz, I was prompted to think about critical minerals that could also have massive disruptive impact in geopolitical turmoil.

I asked Claude “Can you build a dataset of the most critical minerals, where they are mined (mine sites or countries), shares of world production, price changes over 5-10 years, main usages so that we can build a map of these commodities. Build it in a way that we can extend if we find more data” and it found me some data using these sources:
