I was interested in finding walkable areas in a city I had never visited before. After using OpenClaw bot to summarize my JSON files, I thought I could do the same for OSM-based metrics.

I started by generating an OSM extract with a 5km radius from my hotel. I then extracted the geometry and tags for every way, park, building, and tourist attraction in this area. I normalized the raw data into a handful of generic classes like “Food & Café” and “Nature / Quiet.”

I then assigned each way and point of interest to an H3 hexagon. I calculated aggregate metrics for each hexagon, like the length of roads and the area taken up by parks and water. Then I simply fed the metrics for the hexagon to Ollama with Mistral Nemo, asking it to generate a short one-sentence vibe of a place based on the collected metrics and label it as positive, negative, or mixed.

To visualize the results, I created a KML file and imported it into Google My Maps. I had to iterate on the LLM prompts, as there are a lot of fields in the generated JSON and the LLM struggles to interpret what the numbers mean.

I also discovered a number of bugs in how I calculate features per H3 hexagon, but I eventually arrived at a reasonable overlay showing how walkable each area is. It’s not perfect — partly because OSM data is incomplete for the area I picked, and partly because I need to make my prompts more specific.

The recommendations are generic, but they add an extra dimension to the map. I think this is really exciting because you can create any perspective you like on OSM data with your own overlays for driving, finding a house, or finding a place to eat.





Hallo allerseits,

ich bin dabei, in Südfrankreich in einem Waldgebiet neue Wege zu kartieren. Die Wegpunkte habe ich mir als GPS- bzw. UTM31-Koordinaten notiert. Aber um sie auf der OSM-Karte an der richtigen Stelle einzutragen, bräuchte ich eine Karte mit Gitternetzlinien (am besten im Abstand von ca. 10-100m). Wie geht das? Danke! Martin

At the suggestion of a friend, I decided to install StreetComlete and give OpenStreetMaps a try. I’ll be adding data as walk and bike and hike around the area.
