What is OpenStreetMap?
OpenStreetMap (OSM) is a global, community‑built map of the world, created by volunteers who survey their local areas and add details like roads, paths, buildings, shops, cycle lanes, benches, and accessibility info.
Think of it as Wikipedia, but for maps — open data, editable by anyone, and used by thousands of apps, services, and research projects.

✨ What you can do on OSM

🗺️ Browse the world map — detailed, constantly updated, and fully open.

✏️ Edit the map — fix mistakes, add missing places, improve local data.

🚶 Plan routes — built‑in directions (car, bike, foot) powered by open routing engines.

📤 Upload GPS traces — contribute your own recorded tracks to improve accuracy.

📚 View edit history — every change is transparent and publicly logged.

🌍 Join communities — local mapping groups, events, and global projects.

❤️ Support the project — donate to keep servers running and data free.

OSM is one of the most important open‑data projects on the planet. It powers humanitarian mapping, disaster response, navigation apps, research, and countless tools — all without corporate lock‑in.
