Software puts images on the map

   June 23/30, 2008
An image processing system can tell where in the world any given outdoor photograph was taken with an accuracy 30 times better than chance. The system works by matching pictures to the more than 6 million images on Flickr that are tagged with GPS data.

The system could help with environmental, economic and political analysis of photographs.
