The collection of photos at flickr provides invaluable statistical data about a host of cultural behaviors and norms. Previously, we wrote about using flickr’s geotagging as a measure of cultural buzz. Now, a new project called Locals and Tourists by Eric Fischer analyzes the differences between where (and, presumably, what) locals and tourists take photos in cities around the world. There’s New York and London, Amsterdam and Paris, Hong Kong and Tokyo, and many more. Blue points on the map are pictures taken by locals (people who have taken pictures in this city dated over a range of a month or more). Red points are pictures taken by tourists (people who seem to be a local of a different city and who took pictures in this city for less than a month).
