OpenStreetMap was founded in 2004 and is an international project to create a free map of the world. To do so, we, thousands of volunteers, collect data about roads, railways, rivers, forests, buildings and a lot more worldwide. Our map data can be downloaded for free by everyone and used for any purpose – including commercial usage. It is possible to produce your own maps which highlight certain features, to calculate routes etc. OpenStreetMap is increasingly used when one needs maps which can be very quickly, or easily, updated.
