OpenOrienteering Mapper is an orienteering mapmaking program and provides a free alternative to the existing proprietary solution. Its main advantages compared to it are:

  • Open Source: the program is completely free, every programmer can improve it.
  • Cross-platform: the program works on Android, Windows, Mac OS X and Linux.

While it is under continuous development and considered in beta state, it has been used to produce maps for classical orienteering, MTBO and radio orienteering races. All required functions for drawing maps are implemented and the program works very stable. So it can be considered ready for productive use, although it is like always a good idea to keep backups of your files. We are happy about feedback to the program.

The online manual can give you more ideas of what the program does.


There is a lot to do, and we appreciate every kind of help, whether you are a programmer or not. As an example of a programming free task, ‘official’ symbol sets for MTB and Ski orienteering maps are still missing. If you are interested in contributing, good places to start are:
