Map Kibera trained hundreds of young people and professionals last year, to contribute to OpenStreetMap and report on their communities. We created manuals, and as all of our work and outputs are shared in the commons, we’re releasing them here.
The single best consolidated open guide for teaching OpenStreetMap is definitely LearnOSM. If there’s any place I think the Map Kibera materials could contribute, it’s the GPS Surveying Guide, which goes into quite good detail on field survey techniques.
GroundTruth also produced materials for the Swaziland mapping project. The GPS Coordinator Manual may particularly be of wider use, at it describes precisely how to configure Garmin GPS units for surveying with OpenStreetMap.
