OpenStreetMap 2008: a year of edits

OpenStreetMap is a wiki-style map of the world. In this animation, each time a feature is entered or updated it flashes white and then decays through yellow and red to purple. Some edits are a result of a physical local survey by a contributor with a GPS unit and a notepa. Other edits are done remotely using aerial photography or out-of-copyright maps. Large areas of simultaneous edits are the result of bulk imports of official or donated commercial data.
