UPDATE: Fox News in Atlanta has a segment on the OpenStreetMap mapathon.
OpenStreetMap is gearing up for a three-day mapping marathon to map with a goal of making the city of Atlanta one of the best mapped in the United States. Over 200 volunteers are expected at the event and will be given GPS units in order to map “everything from bike paths to emergency phones and police precincts.” BBC News has a write-up on the event.
