OpenTopoMap is a topographic map out of data from OpenStreetMap and SRTM. If you are interested in building your own OpenTopoMap, see the beginner's guides for a tile server and for Garmin files.


The main OpenTopoMap is a online rendered raster map. It can be used with the web interface on, which gives you nice features like a search function or loading your gpx tracks. Futhermore, OpenTopoMap can be included into other applications. See for information on usage. The license of the online map is CC-BY-SA.

The online renderer is based on Mapnik. All necessary files are available to build your own OpenTopoMap server.
