this is likely an aerial imagery disturbance between tiles

this is a part of the electricity delivery infrastructure, based on aerial imagery; needs an on-ground survey to define more specifically.

should this waterway be marked as "intermittent"?

I've not mapped this as a building as it appears to me to be composed of fencing not walls, some form of fenced enclosure.

Should this way parallel to the Trunk be mapped? If so, should it be 'unclassified' or 'service' (referring to the "Highway Tag Africa" OSM Wiki values).

extends into next editing area

additional mapping of buildings and water could be done

way exends into new mapping area

more detail mapping needed in this area

is this maybe a wetland area?
