Free access to streets information around the world

Geographical data is usually expensive around the world. Google brought a great contribution to that, but still all Google Maps information is copyrighted. So these guys here started a great project: the OpenStreetMap ! This is a collaborative project where people can share public datasets on streets information around the world.

And this is a beautiful animation showing edits to the project during 2008.
