The most beautiful maps are somehow useless. You look at them not to decide where you’re going, but rather to see constellations that are rarely visible: details that, from the ground, never coalesce into a coherent picture. Eric Fischer has fashioned a set of maps that depict just such constellations. Using photographs from Flickr and Picasa, Fischer has placed a colored mark on a map where each picture was taken. As he explains:
The results (above is Stockholm) trace where people go and what they photograph, arcs and blocks and spangles of presence.
