Locals and Tourists maps show where visitors and locals take pics in major cities

Eric Fischer's "Locals and Tourists" Flickr set uses geotags to compare photos taken by locals (people whose photos come from the same city, over long terms) and tourists (people whose photos come from a city for less than a month, and who have some other city they usually post from) and produces colored maps showing the difference. Readers use Flickr's annotator to add explanatory notes. Here's London.
