xml data

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.

A full copy of our planet earth database is available here and minutely replication files are available here.



New contributors are very welcome.

If you would like to try it out just create an account and configure your favorite editor. We currently support JOSM and Merkaartor. Please see our getting started page for more information.

Please check our wiki for further help and please also join our mailing list to keep up-to-date with current developments.
