Very interesting result. The volunteers, local people make map using free and open source GIS tools, and using OpenStreetMap. But it wasn't just a means to an end as the exercise proved that there were areas not in the official village, and areas in the village were not in the official map. That showed a problem with official records and lead to the government agreeing to redraw the official maps, properly surveyed. I'm not sure if that work has been done or if they don't have the money.
