OpenAerialMap

OpenAerialMap was a project which aimed to create an open collection of aerial photographs. It was available at http://openaerialmap.org/ between November 2007 and December 2008. If you are interested in implementing a similar project, please feel free to discuss the idea on the "talk" mailing list.

Microsoft now provides aerial imagery that can be used as a source of data whilst editing OpenStreetMap. For more see 'Bing'.
