Kathmandu Living Labs (KLL) has started “project Ilam” together with Marek Kleciak, Heinz_V and WojtekK. The main goal is to get the utmost possible data accuracy using new high resolution imagery from Bing and Digital Globe in the district of Ilam, Nepal. The wiki page of this project describes how to identify such areas from aerial images. The project should demonstrate to the authorities in developing countries the usefulness of OpenStreetMap. The area should act as test area for comparing armchair mapping data to the reality in the field and support governments and NGOs. The project is looking for experienced mappers: sorry, no newcomers.
