Many digital photos are now geotagged– stamped with the latitude and longitude coordinates for the location where they were taken. David Crandalland colleagues at Cornell University in Ithaca, New York, have analysed this data, using 35 million photographs uploaded to the Flickr website.
Crandall's team found that the data offered a simple way to organise millions of photos on a global scale. Simply plotting that raw data onto an empty canvas revealed accurate maps, like this one of the 48 lower states of the US.
