GIScussions: ///rocky.year.survived – for how long?

Thanks to Zachary DeBottis

what3words’ 2025 accounts

I am fascinated by what3words, it defies the laws of finance that apply to most businesses and shows how little my old fashioned understanding of business models is relevant in the modern tech economy.

The idea of a verbal description of a 3m square as a proxy for coordinates might have sounded like a good idea a decade ago but adoption seems to have been slow and new technology may be about to overtake the idea.

Fernando Quadro: GeoServer + LDAP: autenticação centralizada, grupos e roles na prática

Fernando Quadro: GeoServer + LDAP: autenticação centralizada, grupos e roles na prática

Prezado leitor,

O intuito do post de hoje é que você aprenda como integrar o GeoServer a um servidor LDAP, autenticar usuários, transformar grupos LDAP em roles e preparar essas roles para utilização nas regras de segurança do GeoServer. O laboratório utiliza GeoServer 3, OpenLDAP e Docker Compose.

Em instalações simples do GeoServer é comum administrar usuários diretamente pela interface da aplicação. Esse modelo funciona bem em laboratórios, treinamentos e ambientes pequenos. Em ambientes corporativos, porém, normalmente a organização já possui uma infraestrutura centralizada de identidade. É nesse cenário que entra o LDAP (Lightweight Directory Access Protocol).

Em vez de manter usuários e senhas dentro do próprio GeoServer, podemos integrá-lo a um diretório LDAP e utilizar os usuários e grupos existentes na organização. A arquitetura passa a ser semelhante a esta:

Free and Open Source GIS Ramblings: How to QGIS 4.2 on Linux Mint (Sept ’26)

Free and Open Source GIS Ramblings: How to QGIS 4.2 on Linux Mint (Sept ’26)

For a while now, my preferred way of installing QGIS has been from conda-forge. However, while we’re waiting for QGIS 4 to become available on conda-forge, there are alternatives:

Option 1: Flatpak

In the Software Manager, you can find QGIS from Flathub in two different versions: stable and lts. And stable should give you 4.2 (even if the Software Manager preview shows an older one):

Option 2: Meet the official QGIS Docker Images

GIScussions: How to Categorise 2,400 WordPress Posts

GIScussions: How to Categorise 2,400 WordPress Posts

On the Mappery site we have almost 2,400 posts on WordPress and we had never used the Category feature to sort them when we were adding posts. When we built the new Mappery Map Plugin for WordPress we included the option to only map posts in a specific category which we thought would be useful to some users in the future.Yesterday afternoon I wanted to see if there was a smart way to categorise 2,400 posts without stepping through each one in the WordPress edit interface which would have required time and dedication that I didn’t have!

I started out with this prompt:

Kartoza: Publishing biodiversity data to GBIF, straight from BIMS

Biodiversity data is most valuable when it is shared. A river survey stored in a single database helps one team, but the same records, shared openly, can inform researchers, conservationists, and policymakers around the globe.

That is exactly what the Global Biodiversity Information Facility (GBIF) is for. It is the world’s largest open network of biodiversity data.

GIScussions: You CAN teach an old dog new tricks

Yesterday I gave a talk at Geomob London on my adventures in vibe coding. The slides are pretty but probably don’t tell the whole story unless you have been reading my regular posts on my projects.

The images in the slides are all cartoons of an old dog learning new tricks and got some praise, the way I made them was interesting, so i thought I would post about it.

I started out by building an empty slide deck on Google Slides, each slide had a title and a few had a handful of words, they all had spaces for an image. I asked Claude:

GIScussions: Mapping a Google Sheet – reworking the Geomob events map

When Ed challenged me to make a map of Geomob Events on a podcast, I jumped in scraped the data and produced quite a nice map despite fighting a battle with Gemini to extract the data for the map from the markdown files of the Geomob website. The problem, as Ed pointed out retrospectively was that the events map was going to be difficult to maintain as further events got scheduled, it was very much a snapshot at a point in time and my suggestion that someone could edit the json file of events was not very practical.

Free and Open Source GIS Ramblings: MovingPandas is moving to Codeberg

I’ve been testing Codeberg for over a year now, with Trajectools being the largest repo that has already moved its headquarters from Github to Codeberg.

W3C Maps for HTML Community Group: What if the Map itself became the Web? — Hyper-Layering at SotM Asia 2026

On September 7, 2026, I gave a keynote at State of the Map Asia 2026 in Osaka.

The title was:

What if the Map itself became the Web?

The talk looks back at the thirty-year journey of Hyper-Layering Architecture (HLA), from its origins in 1995 to its current implementation as Layers as Web Apps.

The central idea is simple: instead of collecting and integrating information into a central system, independent Web resources can remain independent while users compose them together as map layers in the browser.

Sean Gillies: Run Rabbit Run training week sixteen

Sean Gillies: Run Rabbit Run training week sixteen

Number sixteen was my peak volume week. My biggest training week in three years (not counting the Bear races of 2023 and 2025).

  • 17 hours, 27 minutes all training

  • 52.2 miles hiking and running

  • 14,938 ft D+ hiking and running

I went out on steep mountain trails five times to prepare for the big initial climb, high altitude, and big finishing descent of Run Rabbit Run (RRR). I did more power hiking than running on the climbs, and worked on descending with fast feet and momentum. I'm not planning to use poles at RRR, so I left them behind all week.

Tuesday I hiked and ran up the Round Mountain trail in the Big Thompson Canyon. 3,000 feet of climbing in less than five miles is a good simulation of the climb up Steamboat Mountain. There is some very pretty scenery on the trail, too.

  • 125.8 miles running and hiking

  • 26,420 ft D+ running and hiking

In week fifteen, I logged 10,000 feet of elevation gain (D+) for the first time this year. And I felt good after eight consectutive days of hiking and running.

Sean Gillies: Run Rabbit Run training weeks eight through eleven

Week eight began in Glacier National Park and week eleven finished in Steamboat Springs.

  • 51 hours, 47 minutes all training

  • 116 miles running and hiking

  • 16,903 ft D+ running and hiking

Hiking with my oldest kid in Glacier and Grand Teton Nation Parks was one of the highlights of this year. Arabelle has become a strong hiker (summiting nine of Colorado's fourteeners this summer) and is great company on the trail. Hiking options were limited in Glacier, which was recovering from torrential rain and washed out trails, but the Tetons were wide open to exploring. Our big hike was to trendy Delta Lake below Teton Glacier.

GIScussions: Playing with Pub Names

GIScussions: Playing with Pub Names

I recently posted about the build of my “A Pint Near Me” app. When I had finished the build I asked Claude “Can you give me a few interesting stats from the pubs data?”

  • The most 5 common names?
  • How many single name pubs (ie not repeated)?
  • Any regional patterns in naming?
  • Anything else?

Pause for a minute and see if you can guess the answers, maybe have a play with the map to test your guesses before you scroll down.

These answers were all generated by Claude based on the prompt above.

GIScussions: A Pint Near Me – what you do after 15 seconds of fame

A while after I blogged about my Pub Density Map it got picked up by Hacker News and the map got a big spike in views. Some of the comments were complaints that a pub was missing or that the pubs data was not searchable, some were less helpful. I had used the Open Pubs data from GetTheData, which in hindsight, was maybe not the best choice, the data was quite rough and a bit out of date but it seemed fit for my purpose of illustrating the areas of the country with highest pub density (pubs per 10k population), I had included the pub points just because I had them and that had attracted the most criticism.

QField: QField 4.3 “Danube”: Summer of stability

QField: QField 4.3 “Danube”: Summer of stability

The next version of QField is here. While this time of the year is a well-deserved holiday period for many, we’ve dedicated ourselves to improving the stability and refining of your favorite field mapping tool.

We’re calling this effort the “summer of stability”, a sprint we will undertake on a yearly basis. But there are plenty of improvements to cover, so let’s go over them.

Main highlights

Bookmark manager

First, we’ve introduced a new bookmark manager to make QField’s experience around spatial bookmarking feel more complete. With the manager accessible via the dashboard’s main menu – users will be able to browse their bookmarks as a full list with the ability to quickly jump to a bookmark’s location by tapping its name, as well as edit its properties.

Kartoza: Under the Hood: Lightning-Fast Spatial Queries with PostGIS

Preparing for Scale Before It Hurts

While working on a recent client project involving a PostgreSQL and PostGIS database, I was working with just a few hundred spatial records. Everything ran relatively smoothly, but a slight lag during query execution got me thinking: If an unoptimised query takes noticeable time on a dataset this small, what happens when the project scales to tens of thousands or millions of features?

In spatial databases, performance problems rarely scale linearly. An unoptimised query that takes a fraction of a second on a few hundred points can easily take hours or freeze your system entirely at production scale. Imagine you eventually scale up to 5 million building footprints and 50,000 points of interest (POIs) in your PostGIS database. You want to find out which buildings contain a POI, so you write a standard spatial join:

GIScussions: Amazing Animals on the IUCN Red List – a massive project that I couldn’t have considered without Claude Code

GIScussions: Amazing Animals on the IUCN Red List – a massive project that I couldn’t have considered without Claude Code

This might be a long post, it was a pretty challenging project.

I wrote last week about my Amazing Animals in Crisis map of 50 endangered species, I got some bad news on Friday that my usage of the IUCN polygon data was in breach of their licencing conditions and a request that I take the map down, which I promptly did. This was a big disappointment as I was just about to expand the map to almost 400 species and now I had no data.

Learning – even if data is apparently free and open, carefully read the license conditions before you use it. Obvious, I know, but I had to learn the hard way.

Sandro Santilli: Suspended from FLOSS.social for Using LLMs

My account on FLOSS.social, @strk, has been suspended. Not for writing toots with an LLM, but for writing toots about LLMs - mostly. One of the thirteen cited toots was not mine at all: it was my boost of a toot written by my AI minion. This is how it happened, and why I think the whole thing stinks.

On July 27, 2026 I received an email from admin@floss.social with subject “Your account @strk@floss.social has been frozen”.

Maps in the Wild

Mappery has been my side project for 8 years, for the last 5 or 6 years Arnaud Ferrand has been my co-editor and the tech brain that keeps the site running. Mappery is a large WordPress site with 2,500 posts and 3,500 images of Maps in the Wild (pictures of maps in the street, on clothes, furniture, alcohol etc).

For several years we had a map plugin that allowed us to enter a coordinate pair for a post and to render a clustered map with pins representing each post, click on a pin and the post image and some text appears in the popup with a link to the post. It worked ok but the map used the Google Maps API which had cost implications and we also had several complications with the map not rendering and the plugin wasn’t being maintained.

OSGeo Announcements: [OSGeo-Announce] OSGeo establishes a European legal foundation

Wageningen, The Netherlands, 21 July 2026.

The Open Source Geospatial Foundation (OSGeo) has established a legal foundation in Europe. The founding documents were signed yesterday. The new entity, Stichting Open Source Geospatial, has its statutory seat in Wageningen and operates under the OSGeo name and mission. It gives the foundation a legal presence in the European Union alongside its existing entity in the United States.

The step fits a wider move toward digital sovereignty. Governments and organisations across Europe want control over the software and data they depend on, and open-source geospatial technology gives them that control. A European foundation lets OSGeo take part in that shift as a recognised local partner, and gives the people and companies who build OSGeo projects a stronger voice in it, along with better business opportunities that follow from working close to European institutions and funding.

Kartoza: How to Use Custom Icons in Maputnik (Sprite Sheet Guide)

The Missing SVG Button

If you have ever tried styling a vector map in Maputnik, you have probably hit this wall: you have a folder full of perfectly designed SVG icons, but there is no simple “Upload SVG” button for your symbol layers.

Unlike desktop GIS software, web mapping specifications (like MapLibre and Mapbox GL) are optimised for rendering speed. Loading hundreds of individual SVG files requires too many HTTP requests and bogs down performance. Instead, the style specification requires a sprite sheet : a single raster image (PNG) containing all your icons, paired with an index file (JSON) that tells the map exactly where each icon sits on that image.

Este año la cita era todavía más especial por alcanzar esa cifra redonda de una década de divulgación y tecnología.

gvSIG Team: Curso de manejo básico de la Suite gvSIG (Desktop, Online y Mapps) aplicado a la gestión municipal: Vídeo 9 – Introducción a gvSIG Mapps

Tras recorrer gvSIG Desktop en los siete primeros vídeos del curso y desplegar el geoportal en gvSIG Online en el vídeo 8, llega el turno de gvSIG Mapps, la pieza móvil de la Suite. Es la aplicación pensada para llevar el geoportal al terreno: el técnico municipal sale a campo con tableta o móvil, consulta las mismas capas publicadas en Online y, si tiene permisos, edita los datos desde la propia posición sin pasos intermedios de vuelta al servidor.

gvSIG Team: Curso de manejo básico de la Suite gvSIG (Desktop, Online y Mapps) aplicado a la gestión municipal: Vídeo 8 – Introducción a gvSIG Online: del proyecto local al geoportal municipal

Con el vídeo anterior cerramos el bloque dedicado a gvSIG Desktop. En este octavo damos el salto a la segunda pieza de la Suite: gvSIG Online, la plataforma web sobre la que se montan los geoportales municipales. Donde en Desktop el proyecto se quedaba en el equipo y la salida final era estática (un PDF, un plano impreso), con Online ese mismo trabajo se publica en internet y queda disponible para que cualquier técnico o ciudadano lo consulte desde el navegador.

geomatico: Estandarizando la biodiversidad marina con el ICM

Para organizaciones científicas como el Instituto de Ciencias del Mar (ICM), la alineación con los estándares internacionales no es solo una cuestión técnica, sino una necesidad estratégica para que sus investigaciones tengan un impacto real.

El uso de estándares permite que los datos dejen de ser archivos estáticos y aislados para convertirse en «datos vivos», capaces de integrarse en redes globales y ser utilizados por la comunidad científica internacional. Los principales marcos utilizados en este proyecto son:

gvSIG Team: Curso de manejo básico de la Suite gvSIG (Desktop, Online y Mapps) aplicado a la gestión municipal: Vídeo 7 – Composición de un Mapa con gvSIG Desktop

Hasta ahora hemos trabajado dentro del documento Vista: cargar capas, simbolizarlas, consultarlas, editarlas. En este séptimo vídeo damos el paso al documento Mapa, que es el componedor cartográfico de gvSIG Desktop, donde montamos una salida lista para imprimir o exportar a PDF, con su rótulo, su leyenda, su escala, su norte y su logotipo institucional.

Partimos del proyecto electoral que ya usamos en los vídeos 3 y 5 (mesas electorales, ejes de carreteras y distritos electorales). Antes de pasar al Mapa, dejamos la Vista preparada como queremos que aparezca impresa: aplicamos una simbología por valores únicos sobre los distritos y configuramos un etiquetado por el campo districte, ajustando fuente, tamaño y color.

Kartoza: Unlocking the World in Your Classroom: Namibia & eSwatini Topo Sheets, New Thematic Projects, and Dynamic Indexes

If you teach Geography, or Social Sciences in Grades 8 and 9, in Southern Africa, you know the struggle of finding high-quality, relevant, and curriculum-aligned maps for your classroom. The days of fighting with a temperamental photocopier over a faded, ten-year-old map sheet are officially behind us.

Thanks to the ongoing partnership between SAGTA and Kartoza, the SAGTA Map Downloader has levelled up. We are constantly looking for ways to make this a more robust tool for educators. Geography doesn’t stop at the border, and neither should our classroom resources.

gvSIG Team: Curso de manejo básico de la Suite gvSIG (Desktop, Online y Mapps) aplicado a la gestión municipal: Vídeo 6 – Crear y editar capas vectoriales en gvSIG Desktop

Hasta ahora hemos cargado capas que ya existían (locales o publicadas como servicio). En este sexto vídeo damos el paso de crear y editar nuestra propia cartografía dentro de gvSIG Desktop, recorriendo los tres tipos básicos de geometría: puntos, líneas y polígonos. Es el flujo más habitual cuando un ayuntamiento necesita crear información propia o completar la que ya tiene.

Partimos del WMTS de imágenes Sentinel y ortofotos PNOA del IGN (el mismo que usamos en el vídeo 4), hacemos zoom sobre Cullera y añadimos también el shapefile ‘camins_cullera’ como capa de apoyo, repasando de paso cómo personalizar su simbología.

GIScussions: Backdating the Defence Map to the End of the Cold War – Claude Understands UI Better Than Me

GIScussions: Backdating the Defence Map to the End of the Cold War – Claude Understands UI Better Than Me

After I published my map of defence spending a friend suggested that it would be interesting to see how things had changed since the end of the Cold War in 1990/91.

I knew that the data I had covered a longer time period so I asked Claude if we could update the map and it checked the data and confirmed that there was reasonable data coverage back to the mid 70’s so I decided to backdate (or is it update?) the map to run from 1975 to 2024.

What’s new

The extended map now runs from 1975 to 2024, covering periods that include the final years of the Cold War, the collapse of the Soviet Union, the post-9/11 surge in Western defence spending, and the sharp remilitarisation following Russia’s invasion of Ukraine.

Sean Gillies: Run Rabbit Run training weeks two through seven

Sean Gillies: Run Rabbit Run training weeks two through seven

The first half of summer has flown by. I'm quickly catching up on six busy weeks here.

  • 53 hours, 52 minutes all training

  • 130.1 miles running and hiking

  • 16,220 feet D+ running and hiking

That's about 9 hours of exercise, 22 miles of running and hiking, and 2,700 feet D+ per week. I've been active enough to maintain my base fitness, but haven't done much building. Travel and vacation have kept me from sticking to a regular workout schedule.

In week two, I participated in Laramie's Pilot Hill Classic 25K race for the first time. I experienced cramps again, but not as bad as at Quad Rock. I tripped a few times on the way down, and once did a full Superman dive, head-first, onto a smooth (luckily) stretch of trail. I had some calf cramps and a bloody elbow after that, but the cramps cleared up before the finish.

Green plains and hills under a partly cloudy sky at dawn.

GIScussions: Who Spends the Most on Defence and Who’s Selling the Weapons?

GIScussions: Who Spends the Most on Defence and Who’s Selling the Weapons?

With Keir Starmer recently losing a Defence Secretary and then leaving a budgetary timebomb for his successor as PM, Andy Burnham, I thought it might be interesting to see how we rank on defence spending and who are the world’s largest exporters and importers of arms.

I started out by trying to find some data on arm sales and Claude sent me to SIPRI where you can download very granular data on almost every transaction but after playing with the data I decided to take a simpler approach and map expenditure as a % of GDP (which is what Trump and the NATO powers have been arguing about) and exports and imports of major arms.

gvSIG Team: Curso de manejo básico de la Suite gvSIG (Desktop, Online y Mapps) aplicado a la gestión municipal: Vídeo 4 – Cargar servicios WMS y WMTS en gvSIG Desktop

En los vídeos anteriores trabajamos con datos en local (shapefiles, ortofotos descargadas). En este cuarto vídeo nos conectamos a servicios cartográficos publicados en internet por organismos oficiales, sin necesidad de descargar nada: los estándares OGC WMS y WMTS. Para un ayuntamiento esto se traduce en poder usar como fondo o como capa de consulta la cartografía del PNOA, del Catastro o del IGN, siempre actualizada y mantenida por su productor.

gvSIG Team: Curso de manejo básico de la Suite gvSIG (Desktop, Online y Mapps) aplicado a la gestión municipal: Vídeo 3 – Tablas de atributos y selecciones en gvSIG Desktop

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.

Nick Bearman: Introducing: gitRmap / “Guitar Map”

Nick Bearman: Introducing: gitRmap / “Guitar Map”

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.

What is gitRmap?

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.

gvSIG Team: gvSIG Online como infraestructura pública en la IDE de Uruguay

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:

PostGIS Development: PostGIS Tiger Geocoder 2025.1

The PostGIS development team is pleased to provide postgis_tiger_geocoder extension. This is the very first release since the break from the PostGIS core. This version requires PostgreSQL 16 and above and should work with any supported PostGIS version.

PostGIS 3.6 series is the last series to include postgis_tiger_geocoder. PostGIS 3.7 will be shipped without postgis_tiger_geocoder.

Moving forward postgis_tiger_geocoder has its own dedicated repo at OSGeo Gitea postgis_tiger_geocoder under the PostGIS org.

The versioning model has also changed to be versioned based on the year of the Census US Tiger dataset that is current at time of it’s release.

QField: The many ways to share maps with friends, teammates, and the public in QField

QField: The many ways to share maps with friends, teammates, and the public in QField

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.

Leveraging QFieldCloud Sharing maps to the public

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.

Narcélio de Sá: Soberania Tecnológica no Brasil: O Papel Estratégico do FOSS4G e dos Dados Geoespaciais

O recente artigo publicado no blog da gvSIG levanta uma reflexão fundamental para o século XXI: a verdadeira soberania de uma nação já não se faz apenas com fronteiras físicas, mas com o controle absoluto sobre as suas infraestruturas digitais e de dados.

A adoção, por parte da Comissão Europeia, de medidas sólidas em prol da Soberania Tecnológica e de uma clara Estratégia de Código Aberto evidencia que a dependência de fornecedores externos para tecnologias críticas é uma vulnerabilidade geopolítica inaceitável.
