A lot of HOT projects are in Africa and they ask for buildings. Often when
I validate on them I see a fair number of buildings mapped but not tagged
correctly. I'm not saying that all the area=yes untags are from HOT
mapping but a lot of it is in areas where HOT has projects.
Recently I loaded up a couple of African countries in JOSM. Recently I've
tagged more than a thousand untagged ways mainly highways. So there are a
lot more highways showing on the map. Untagged means they don't show.
Many HOT projects seem to like buildings. These are buildings that are
already there but untagged. It's a quick way to add lots of buildings.
The other side of the coin is I think there is a responsibility to clean up
as many of the mappers are registered in HOT. Yes we are part of OSM but
some of the mapping done leaves a little to be desired. It's only when you
load up a big chunk that you see just how many there are. Validation often
isn't happening or its done by inexperienced mappers.
