- Community
- Continuous validation

Why OSM important
- It open for usage and editing
- It mostly the best map (especially outside cities)
- bicycle roads
-
It already help
- ambulance (and fire?) cars on call
- on rescue operation after flood or earthquake
Why not Google/Yandex
- Terms of usage
- Thousands requests + limits can be slow
- Can't get or work with pure data (API only)
- Can't fix (or limited?) mistakes or improve
- Mostly worse coverage
Why not Wikimapia
- Unclear data license (used Google Maps)
- Pure editors and other tools
- Category and text description
- 3D mapping?
- Speed limits?
- Turn restrictions?
- Mostly worse coverage
