Echoing Pierre's comments should we come up with better instructions? I think the requirements for the NGOs are where do people live and how do we get there?
Which suggests we want the settlements and a highway to reach them. This is probably different to normal OSM which sometimes seems to be map everything in sight. Personally I think there are two styles of mapping a settlement. One tightly maps round the buildings the other is looser in nature and maps groups of buildings more loosely. Both have advantages. Tight mapping means you can get a rough approximation of population without mapping every building. Mapping fewer highways would let us cover a larger area for the same amount of effort but how to describe the optimum mix is difficult.
