Decatur Metro � Atlanta – Say or See Something: I’m really unsure about whether I’ve ever posted this before, but this Flickr/Twitter map of Atlanta is still pretty cool. Tweets are in blue, Flickr posts are in orange and where both occur are white. Note the distinct patterns for Hartsfield-Jackson airport, Stone Mountain, Piedmont Park and downtown Decatur.
These maps are courtesy of Eric Fischer, who posted a bunch of these maps for many of the worlds major cities on Flickr.
