I am trying to find a shapefile for Mozambique's Level 4 administrative boundaries. These units are known as localidades, or localities, and there are over 1,000 of them. I've tried all the usual sources: GADM, etc. No source that I have found has anything below level 3 boundaries, which are districts.
Confusingly, some websites refer to level 3 districts as localities, but -- while this may have been correct years ago -- it is no longer right. There are ~450 districts and over 1000 localities in Mozambique.
At this point, I would be happy to find any map of localities, even piecemeal, that I could scan and assemble into a comprehensive shapefile. I am also open to alternative solutions, such as generating approximate polygons from a list of points known to reside within a given locality. But I have not found data that would allow me to do that yet.
