I was mapping in rural Darfur today and discovered an entire city which was completely unknown/unmapped. It did not appear in Google, Bing, OSM or anywhere else, not even as a village dot. It’s 90 km SSE of Nyala, Sudan (latlon: 11.28, 25.14, i.e. http://www.openstreetmap.org/#map=14/11.28/25.14) with an airstrip, two large markets, and large street grid. I’ve mapped it now, anyone care to find a name for the city?
