"Wikipedia of maps" open sources Atlanta map data

OpenStreetMap is my favorite community project in the world. Truly open map data is a huge deal, given how many companies are making money from the stuff. Long ago when I started OpenPhotoVR I'd dreamt of eventually integrating it with OSM, too bad it never gained enough momentum.

Agreed. Also, adjusting street positions is somehow very addictive.

The article reminded me of: http://en.wikipedia.org/wiki/On_Exactitude_in_Science

Wikipedia of maps is called Wikimapia.

I don't see how. The maps used by OpenStreetMap are under a free license, Wikimapia is just proprietary (Google) maps with a bit of user data on top. It's like comparing Wikipedia to Encyclopedia Brittanica with user comments.

But wikimapia has wiki in the name!

Seriously tho, few people realize that wikimapia data is © wikimapia and you are not permitted to create derivative works except for "personal or educational" use.

Actually it's called wikifieldtrip.org too.
