|Braunschweig (Germany)||Continously checking and occasionally editing Braunschweig and surrounding areas.||Ongoing|
|Bornholm (Denmark)||Adding new country roads, cycle tracks and hiking tracks as well as POIs and landmarks on this baltic island, based on logs from a mixed cycling & hiking vacation in August 2009.||Ongoing|
|Grövelsjöen (Sweden)||Started editing cross country ski runs in that area for OpenPisteMap (OPM), based on the trackings of a skiing holiday in March 2009. Also added three ski-lifts and a downhill piste I could do with my cross country skis. Unfortunately the nordic ski runs are not yet visible in OPM Render, but they are in Osmarender.||Done. However there are still many pistes to be added.|
|Auvergne (France)||Added new country roads in that sparsely mapped area, mainly apart from main traffic, based on the tracking of a cycle trip in August 2008.||Done|
