Mapathon Ludhiana 2011
Mapping parties are events where anyone can come and participate in the OpenStreetMap project. OpenStreetMap is a free, open source map that can be contributed, edited and used by anyone anywhere. Mapping parties are social events where experienced and new mappers can meet to share and learn more about the project. The events are generally held in a public place, and allow time for discussion, mapping and editing. The event is open to all.
It's fun. It's free. You can help.
