WhatWasThere, a Crowd Sourced Historical Photo Map of the World

WhatWasThere is an ambitious project to create a crowd sourced interactive photographic map of the world that includes present day and archival photos. Photos, tagged with their location and year, are uploaded by WhatWasThere members on the website and via an iPhone app. Uploaded photos can be viewed on a Google Map of the world. WhatWasThere is by Enlighten Ventures of Ann Arbor.
