In an amazing feat of cartography, Eric Fischer turned Flickr’s collective geotagging data into a world atlas of photo hot spots, by city. Better yet, they’re color-coded — blue for locals (taking photos in each city for a month or more) and red for tourists (taking photos in the city for less than a month/locals of a different city). Above: NYC and SF.

Yellows, swirling suspiciously around Moscow’s main streets and idling about Vegas outskirts, are the undetermined. Notice the various Brooklyn parts yet un-plagued by red and the curious tourist swarms around WTC. See the tourists huddled around NOLA’s Burgundy and how only tourists take pictures of Vegas and Tokyo looks like a cluster of neurons.

See them all here, but first, a sampling of the art-worthy maps.
