State of the OpenStreetMap

Posted to Maps  |  Tags:  |  Nathan Yau

OpenStreetMap, the free wiki world map that offers up high quality geographic data, has grown a lot in the past eight years. The OpenStreetMap Data Report shows all these changes. Says the report: “The database now contains over 21 million miles of road data and 78 million buildings.”

There are various parts to the summary, but the star is clearly the map of edits. Green indicates an older edit, and white indicates more recent edits. Blue and pink represents everything else in between. Above shows the global overview, but it gets most interesting when you zoom in on cities.
