Imagery Details

This imagery is from Digital Globe’s WorldView-1 satellite taken on February 2, 2012.

Instructions

Map roads (dirt roads) and smaller paths for as far as you can follow them. Tag roads according to the Highway Tag Africa wiki page. Most roads connecting villages should be unclassified (if they are not yet traced and classified) with only occasional small clusters of isolated houses being connected to the road network by a path (only use path if it would be too small to even drive a 4x4 vehicle on). Tracks are used for ways going to fields or into the forest (but not to another residential area).

Water streams are really important in this response too. waterway=stream is the most usual tag for this type of object in the area.

Also trace landuse=residential around clusters of houses. Another common and useful feature to tag is school areas, easily identified as 1 or 2 long builidngs at the edge of the village, sometimes with two small toilet buildings behind them. The schools are almost always accompanied by a large open area for the children to play in, tag the whole area of the school complex with amenity=school and trace the school buildings and bathrooms. No need to trace all other visible buildings.

If an offset is observed, use Bing imagery (where available) to check data alignment. Bing imagery is the reference for the georeferencing. Move/redraw the data if necessary And then align the WordView-1 imagery on the vector data (and not the contrary).
