Buildings: Please label all buildings as general buildings. The Peace Corps Volunteer and the community will add their detailed local knowledge to the map after we complete the task.
Square the corners of all buildings by pressing “S” on your keyboard after labeling the building. You may see huts; make your buildings perfectly round by pressing “O”.
Compound Walls Use the Line tool to trace walls. Label them by searching "wall" in the "Search Features" panel.
Roads: “The road conditions in Africa do not always correspond to their economic and social role. A road typology should be based on the road importance and not on the surface or the visual appearance of the road”. --Highway Tag Africa, OpenStreetMap Wiki
It can be hard to know the economic and social role of a road, but we can guess that a road is important to trace if it connects other roads, clusters of buildings, or towns and villages. Please use the tags below, taken from the OpenStreetMap Wiki:
Tertiary Road: The roads interconnecting villages and the major streets in towns of some importance.
Residential Road: The roads in residential areas except for major streets that interconnect with various roads (i.e. primary, secondary, tertiary).
Unclassified Road: The roads serving for interconnection of smaller villages and hamlets.
Track: The small roads going outside the residential areas, mainly for agricultural and forestry purposes. In general these roads do not have a connecting function with other roads.
