Flickr user Eric Fischer has done something very interesting. By accessing the geolocation information in photos uploaded to Flickr and Picasa, he’s been able to map out the locations that tend to be photographed by locals and those that tend to be photographed by tourists.
Blue dots are for locals (people who have taken pictures in a city over a period of a month or more), red are for tourists (people who took pictures in a city for less than a month) and yellow dots represent photos of undetermined origin.
Eyeballing these maps, it appears as if tourists tend to take photos at a handful of common locations, while locals tend to take photos primarily everywhere else. UCLA/Westwood seems to be the exception to that trend. It also appears as if those who live in Pasadena (at least among the photos included in this analysis) don’t use their cameras all that much.
I wonder what would result if I mapped my photos onto these images?
