The routes are overlayed on the standard OpenStreetMap and optionally a hillshading layer. The route map is generated from data from the [OpenStreetMap](http://www.openstreetmap.org) (OSM) project. OSM is a freely editable world map where anybody can participate. Which means that it is by no means complete, but it also means that you can contribute by adding new routes and correcting mistakes in existing ones. To find out more about OpenStreetMap, see the [Beginner's guide](http://wiki.openstreetmap.org/wiki/Beginners%27_Guide).
