Improve the World Map
OpenStreetMap is a free map of the world that anyone can edit, and your local knowledge makes it better for everyone. You can add missing sidewalks, trails, shops, and buildings you know, right from a web browser. It is used by charities, researchers, and apps everywhere, so your edits genuinely get used.

“Loved this one — the organizer had everything set up before we arrived and explained exactly what we'd be doing. It ran about 30 minutes long, which caught a few of us off guard, so plan for that. Would definitely come back.”
💡 Bring closed-toe shoes and a water bottle — it gets warm.
