OpenOrienteering Mapper

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, macOS 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.
