Placeopedia is an online application which integrates Google Maps images and Wikipedia encyclopedia articles.See http://en.wikipedia.org/wiki/Placeopedia andhttp://www.placeopedia.com/.
The Board are currently working on a logo licensing contract which would permit such sites to use the Wikipedia logo.
A new mailing list for Placeopedia has recently been created at http://www.mysociety.org/mailman/listinfo/mysociety-maps and they would welcome input from Wikipedians on various aspects of the site.
For example, some issues already raised are whether links to Placeopedia should be added automatically to all Wikipedia articles that have a corresponding entry in Placeopedia. There is already a template for this on the English Wikipedia (http://en.wikipedia.org/wiki/Template:Placeopedia) but so far any links have only been added manually.
Another issue is whether users of Placepedia should be able to add categories to Wikipedia directly from Placeopedia.
If you have an interest in maps, please join the mailing list to help answer these Wikipedia-related questions. http://www.mysociety.org/mailman/listinfo/mysociety-maps
