In 2008, the Prix Ars Electronica jury recognised “OpenStreetMap” by an uncredited artist (Digital Communities) with a Honorary Mention.
“OpenStreetMap“ is a free wiki map of the world, editable by anybody. Users use GPS traces or aerial imagery to add roads, footpaths and other vectors together with points of interest, such as cafes. It is three-and-a-half years old and has 26,000 users, growing at 2,000 a month all over the world.
