OpenStreetMap is a collaborative project to create a free editable map of the world. It provides street maps and geographic data that has helped rescue teams by giving them detailed maps. OpenStreetMap data is freely available and can be used on devices like GPS units and Kindle e-readers to provide maps for areas without commercial coverage.
