Wikipedia of maps is called Wikimapia.

[pieter]

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.
