How not to map is OSM

----

- Data from copyrighted maps 
- Overlaying from copyrighted maps 
- Re-mapping from copyrighted maps
- Mapping a place you have not verified or seen

====

### Why not Google Maps

----

- No access to underlying data (but its data about us and around us)
- Dont allow deriving data from their maps
- Dont allow copying & re-dustributing with a different license
- High costs for usage of data
- No cycle routes or footpaths etc
- Google branding everywhere
  - Comes along google tracers tracking you.

### Sustaining your contributions

----

- Map
- Explore JOSM and other tools 
- Cartography
- Forest, tree mapping
- More, your imagination is your limit. There is defination for everything.
