such as street maps, worldwide, for free. [1]

OpenStreetMap?

OpenStreetMap creates and provides free geographic data such as street maps to anyone

who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use,

holding back people from using them in creative, productive, or unexpected ways. [1]

OpenStreetMap?

› Wiki-style approach for geodata› Database with nodes, ways and relations› Data is described through tags› Data + tags (database) can be used to render

maps› Everybody can contribute
