fosm is a free map of the planet which anyone can use and contribute to. It is a fork of OpenStreetMap licensed under the Creative Commons attribution and share-alike license CC-BY-SA.
Our geodata is stored in standard OpenStreetMap format as a set of points, lines and areas making it usable for many purposes.
It can be used to make custom designed maps, to create routing applications or to produce interesting data analyses. Most tools that work with OSM data will also work with fosm.
New contributors are very welcome.
