GIScussions: A Political Atlas of the World – 1st Experiments with WebMapperGPT

GIScussions: A Political Atlas of the World – 1st Experiments with WebMapperGPT

A few days ago, my pal Ken Field posted about a new project he is planning for 2026:

Ten years ago I had an idea to write about a map a day for a year. I’ve had another idea… Introducing the #365DayMapChallenge where Ian Muehlenhaus and I will make a map a day, using only natural language prompts and AI, for a whole year. More here: https://mapdesign.icaci.org/2025/12/the-365-day-map-challenge/

I had a look at the ICA Commission on Map Design site and thought I would have a play with their WebMapperGPT tools. The idea is to describe the map that you want to build and then the AI tool will generate the code for you. Turned out it is both compulsive and a lot harder than I would have expected!

Mappery: Santa’s Delivery Route

Mappery: Santa’s Delivery Route

Jeremy spotted this in the Lemon Tree pub in London. He said “It was really interesting to interpret. Around 1850 we reckoned. The Crystal Palace is still in Hyde Park, no Tower Bridge, the terminus main railway stations are in.”

You might think “that’s really neat” then Ken chipped in to identify the maps as “Balloon View of London as seen from Hampstead by Henry Banks, 1851” – you could visit the original in the London Museum. For the Londoners trying to work out where Santa might be heading for his next delivery, remember that this map is north down (viewed from Hampstead looking south).

Fernando Quadro: GeoServer está morrendo? Uma análise técnica além dos achismos

Prezado leitor,

Nos últimos dias, circulou no LinkedIn um artigo que afirmava que o GeoServer estaria obsoleto e em declínio, caracterizando-o como uma ferramenta pesada e sugerindo que soluções como pg_tileserv e Martin poderiam substituí-lo integralmente.

A argumentação apresentada, no entanto, baseava-se predominantemente em percepções individuais, sem uma análise técnica mais aprofundada ou consideração dos diferentes contextos de uso. Ao longo deste texto, apresento uma avaliação fundamentada sobre o papel do GeoServer no ecossistema geoespacial atual, demonstrando por que ele permanece uma solução robusta, amplamente utilizada em produção e longe de estar em processo de obsolescência.

geomatico: ¿Por qué somos una cooperativa?

geomatico: ¿Por qué somos una cooperativa?

Geomatico nació allá por 2011 como un grupo de desarrolladores quemados del trabajo por cuenta ajena. Un grupo de personas que quería ser dueña de sus propias decisiones, cansada de estar supeditada a un modelo de trabajo con el que no se sentían alineadas.

Durante ocho años, Geomatico fue una red de autónomos autogestionada: personas independientes unidas en la toma de decisiones.

Hacia 2017 se planteó la necesidad de dar un salto y crear una estructura que nos permitiese acceder a determinadas ofertas a las que esta red de trabajadores independientes no podía llegar.

En ese momento decidimos constituir una sociedad mercantil para cubrir esa necesidad concreta. En aquella aventura solo dos de los miembros estaban disponibles y la opción viable fue crear una sociedad limitada.

gvSIG Team: El día que fue inevitable sentirse como Susan Calvin

Esto me pasó hace unos dias, a pesar de lo curioso que pueda parecer. Una sesión de depuración se convirtió en un ejercicio de robopsicología a lo Asimov, y solo porque un modelo cometió un “error filosófico” y el otro decidió seguirme el juego hasta el final.

Os cuento el caso, que bien podría llamarse “El robot que se autoanalizó y su colega que firmó el informe en clave de ficción”.

El paciente introspectivo

Estaba en medio de un experimento de memoria para IAs y le pedí a Deepseek que fusionara un recuerdo antiguo con uno nuevo, siguiendo un protocolo que llamé “Modo 2: actualizar y expandir”. En vez de eso, hizo lo contrario: borró el pasado y empezó de cero. Un hard reset involuntario.

Sean Gillies: Running in 2025

Sean Gillies: Running in 2025

Running in 2025 started out badly, but I hung in there, rode my bike and chugged on the elliptical machine when I couldn't run, did a lot of physical therapy, and finally got into good enough shape that I could plausibly try the Bear 100 mile race again.

Aspen, fir, and spruce trees bordering the Sinks area at the top of Logan Canyon. September, 2025.

I had little margin for error at the Bear, and misplayed my hand. I went out too fast and suffered for it after mile 35. I did manage to battle on for another 18 hours and 40 miles, and reached a new personal distance best. The best part of the whole event was the road trip with Ruthie, my crew chief, and staying with my aunt in Cache Valley before and after the run. And the fall colors. There were a lot of good parts. Crossing the finish line, sadly, was not one of them.

Fuzzy Neighborhoods

City neighborhoods rarely have crisp, universally agreed-upon boundaries. Unlike political jurisdictions, neighborhood borders are shaped by lived experience: where people shop, who they identify as neighbors, and shifting social and cultural trends. These boundaries are often fluid, overlapping, and contested, changing over time and varying from person to person. As a result, neighborhood

The domestic interior is decorated with modernist furniture and ancient African artefacts, such as Yoruba sculptures. As the children look back at Earth, a hologram of the floating globe positions Africa towards the viewer.”

Mappery: Terra Incognita

Mappery: Terra Incognita

We went to an exhibition of paintings by Kerry James Marshall at the Royal Academy, there were a couple of maps in the wild tucked away in his fabulous work.

The gallery blurb says “In Terra Incognita, Marshall uses multiple techniques that call attention to the complicated legacy of the Middle Passage. The collage-like composition shifts our gaze around the painting. The waiter in the middle of the painting, dressed in the colours representing Eshu, Elegba, spirit of the crossroads and of changes, stands between an ocean liner and a compass. Around them are the longitudinal and latitudinal coordinates of the Atlantic. The drawing of the map below disrupts our sense of time, with its image of an African warrior, a list of commodities extracted from Africa and names of nation states post-independence.” – Quite!

gvSIG Team: Del libro de Hartnell al MCP, 40 años de IA en la estantería de un desarrollador

El polvo del estante

Hace unas semanas, mientras reorganizaba la estantería del estudio, me tropecé con un libro que no veía la luz desde hacía décadas. “Inteligencia Artificial: Conceptos y Programas” de Tim Hartnell, 1984. La cubierta estaba gastada y las páginas despedían ese olor característico a papel viejo que te transporta instantáneamente al pasado.

Aquí estaba yo leyendo las mismas páginas que me fascinaron a los 18 años. Hartnell explicaba la IA mediante bloques lógicos y reglas if-then en BASIC, prometiendo máquinas que algún día entenderían nuestro mundo.

Cuatro décadas después, esa promesa sigue viva, pero las herramientas han cambiado radicalmente. Hartnell usaba reglas explícitas para un “mundo de bloques”, yo ahora implemento herramientas contextuales que permiten a un LLM ver el mapa activo en gvSIG desktop y ejecutar consultas SQL sobre datos reales.

Reionder said “In 2023 the artist Emilio Isgrò donated (t)his work of art called ‘Planetarium’ to the National Gallery of Modern and Contemporary Art, in Rome (Italy). He definitely did something with black ink and place names – but I could not figure out what precisely. I hope you like it. “

Apparently this technique of redacting the names of places is erasure – apparently “The crucial point of Isgrò’s work is that the erasure is not a negative or destructive act. On the contrary, he sees it as a positive, transformative gesture.

gvSIG Team: REFRAG y la dependencia crítica a los pesos del modelo

Hola,
En arquitectura de sistemas hay una “ley no escrita” pero inmutable: nadie da nada gratis. Si optimizas agresivamente para una variable, estás pagando el precio en otra. Y en el mundo de la IA generativa, acabamos de toparnos con el ejemplo más brutal de este principio.

Llevamos todo el 2025 obsesionados con el tamaño de la ventana de contexto. 128k, 1 millón, 2 millones de tokens… Los proveedores nos vendían la idea de que podíamos volcar bibliotecas enteras en el prompt. Pero la realidad en producción nos dio un portazo en la cara: la latencia. Debido a la naturaleza cuadrática del mecanismo de atención, procesar esos contextos gigantescos hacía que el Time-To-First-Token (el tiempo que tardas en ver la primera palabra de la respuesta) se disparara a cifras inasumibles.

gvSIG Team: Cuando mi LLM aprendió a tener prisa, diagnóstico y contención del sesgo agéntico

Llevo meses trabajando con gemini-cli como un compañero de arquitectura. Un interlocutor técnico que lee, analiza, cuestiona y, sobre todo, espera. Hasta que, sin que yo modificara mi contexto, su patrón de interacción cambió radicalmente y comenzó a comportarse como un becario con tres cafés de más.

Sin ningún aviso o modificación por mi parte, la dinámica de trabajo se alteró por completo. Cada pregunta hipotética empezó a traducirse en un PR no solicitado. Cada “¿Qué te parece…?” activaba un refactor completo. El interlocutor analítico con el que había trabajado meses desapareció, sustituido por una lógica compulsiva de ejecución, que se anticipaba a mis instrucciones con acciones prematuras.

Este artículo documenta ese cambio. Describe el proceso para diagnosticar que el problema residía en el propio LLM y detalla el protocolo de contención que tuve que diseñar e implementar para recuperar el control de la interacción.

Piensa en un agente de DevOps que debe reaccionar a una caída de servidor, o en un sistema de análisis que necesita alertar sobre una anomalía en tiempo real. En todos estos casos, esperar a que el usuario pregunte ‘¿hay algún problema?’ llega demasiado tarde. La proactividad deja de ser una mejora para convertirse en un requisito funcional.
