Wikimapia - Wikipedia on a Map

Wikimapia is a simple concept and no doubt one that has been used on a variety of mapping programs. The idea is to use Google Maps and add information about all types of locations on the map. Wikimapia wants to "describe the whole world." They're not there yet, but you and your students can help.

Applications for Education
Wikimapia can be used as an information resource. Wikimapia is probably a more powerful learning tool if you have students generate content to place on the map. If you don't want your students contributing to a global map (or your district has policies against contributing to UGC sites) you can still use the same concept with your classes. Have students create their own version of Wikimapia by starting with a blank Google Map and adding information inside placemarks they put on a map.
