In scrolling through the afternoon e-newsletters, I was struck by prettymaps, a new edition by Aaron Straup Cope for the art collection site 20×200 that depicts SF (in the artist’s words, it’s intended to “give you that same dizzy feeling you get when you look down at a city at night, from an airplane”). Beyond the colors, I’m intrigued by the sources that local information design studio Stamen utilized for the piece, including Flickr shapefiles and the Open Street Map project. It’s community-generated data at its finest.
