Geo-tagged maps of Krakow and Warsaw

Here’s a cool and non-controversial thingy: maps of Warsaw and Krakow superimposed with visualizations of where people take photos. They were created by a chap called Eric Fischer, along with a lot of similar maps of other cities that you can see on his flickr page.

Using location data added to photos on Flickr and Picasa, Fischer plotted where photos were taken, and then coloured them according to whether they were taken by residents or tourists—a trick he achieved by classifying individuals who took photos in the same city over a period of more than 3 months as residents, and less then 3 months as visitors. Red dots indicate photos taken by visitors, blue by residents, and the yellow are unknown (individuals who took only one photo).

The second map is of Krakow, but in this case the colours represent distance in time between photographs taken by the same individuals. Fischer interprets this as photos taken by pedestrians (black), photos taken by cyclists (red), and photos taken by drivers (blue).
