Are you running from your responsibilities? On our #30DayMapChallenge day 14 entry, we tell you where!

Atmika Pai maps running clubs with OpenStreetMap, which includes amenities such as water and restrooms. Running club data comes from @shaylaruns (Instagram).

Improving OpenStreetMap through CoMaps notes How you can help to improve OpenStreetMap - and thus CoMaps - by reviewing open notes

People can use CoMaps for leaving notes on #OpenStreetMap. Those notes can suggest edits that are outside CoMaps' editing capabilities.

You can help CoMaps & OpenStreetMap by looking over those notes and fixing them. Learn more about how to do so on our website: www.comaps.app/news/2025-10...

Demystifying OpenStreetMap Come learn how to use and contribute to “the Wikipedia of maps,” OpenStreetMap!

OpenStreetMap is the Wikipedia of maps: a publicly-available database of spacial information that anyone can edit. We sit down with prolific OSM contributor Jackson Kruger to talk about the best ways to use the data, and how to get comfortable with contributing to the project.

We recently released OlmoEarth—an open spatio-temporal foundation model for planetary intelligence, trained on multimodal Earth observation, OpenStreetMap, & other open data. It sets a new accuracy/efficiency Pareto frontier and powers our OlmoEarth Platform. Technical report now on arXiv. 👇

New blog post on @mapterhorn.com - terrain for web mapping

TIL that #Mapycom is more than just a renderer on top of #OpenStreetMap. They actually import buildings from #Overture, which #OSM doesn't consider reliable enough for automatic imports.

From what I've seen, the results are mixed in Greece, with many buildings that don't exist in reality.

OpenStreetMap OpenStreetMap is a map of the world, created by people like you and free to use under an open license.

Ever wondered why your company or favorite shop isn’t shown on many maps?
Because the marketing guy can’t think beyond google.
The good news: you can easily fix it yourself:
1. Create an #openstreetmap ( #OSM) account;
2. Improve the map at openstreetmap.org or (easier to start): mapcomplete.org

This month #OpenStreetMap turns 21!

To mark the occasion, we dug into our archives to finish part 3 of Stamen's personal history of OSM, covering the years 2016 to the present. Check it out on our blog, including links to part 1 and 2 of the series:

Beyond Materialized Views: Using DuckDB for In-Process Columnar Caching In this post we will talk about using DuckDB as the operational analytics store for the control plane of Striim Developer — a serverless…

Instead of materialized views, we built in-process DuckDB caching in the control plane of Striim Developer — improving query performance 5–10x with zero added infra.

PostgreSQL for OLTP, DuckDB for Operational OLAP. But I won't call it HTAP 🤐
