I recently joined the GeoMob Podcast to talk about the Map Design Commission's #365DaysofMaps and #PromptCartography project with Vice-Chair Ken Field. We are producing one map a day, every day this year, with AI as collaborator, foil, intern, design partner, occasional menace, and very fast cartographic assistant.
The project started with a simple question:
What happens when two cartographers spend a year testing how far natural language can take map design?
Not just making pictures of maps, mind you, but working through audience, data, symbolization, layout, interactivity, critique, revision, and all the quiet decisions that make cartography cartography.
The short answer is that AI is both impressive and still imperfect. It moves quickly. It surprises you. It also produces confident nonsense with the posture of someone who has never been wrong in a committee meeting. So no, cartographers are not suddenly unnecessary. Quite the opposite. The better these tools get, the more cartographic judgment matters.
Prompt cartography does not replace design thinking. It exposes it. It turns hidden decisions into language that can be discussed, tested, reused, and taught. That is why the work feels larger than a year-long stunt, though the stunt part is definitely helping.
The International Cartographic Association Commission on Map Design is exploring prompt cartography and natural language GIS because these methods point toward a real shift in how maps will be designed. I believe the role for humans in cartography has completely changed already. It is just trickling through the workplace more slowly.
Listen to our thoughts, experiences, and some talk about maps here: Geomob Podcast, Episode 340.
Geomob Podcast, Episode 340, Ken Field and Ian Muehlenhaus: A Map a Day with AI, was released on June 1, 2026.
Happy Mapping!

P.S. Special shout out and thank you to Geomob and Steven for having us on. It was a blast!
