Well. In fact I heard about Uganda OSM community since at least 3 years
and a half ago. You can see these edits were done in mid 2012, and I
followed the discussion on the mapping of entrance gates and other
issues that time: http://www.openstreetmap.org/#map=19/0.30973/32.60403

I actually used a search engine to further assess the data quality.

I wonder if that is legal in the first place. But I would leave this
edits for a second step, and focus on the schools import first. I guess
the import could take 1 month, maybe two. That depends on how many
people take part, and how much time they donate on average.

Hmmm... I didn't think about this advantage. In fact, I was wondering
what the best approach would be for those schools that users won't
import because they are suspicious of being correct. What worries me a
lot is the time and energy it would drain from the already big effort of
importing 24,000+ schools.

Mapillary, I heard, it's already being used quite actively in Tanzania.
I checked at least Dar Es Salaam mapillary, and it has lots of sequences
already, so it could be a good idea for the Uganda local community to
contact those users taking the mapillary photos for advice, as internet
speed may be an issue when uploading hundreds of photos. I've checked
that there is actually one sequence in Kampala:

Most important is not to load the process too much, as this would
discourage people.
Again, as more as the Uganda OSM community takes this effort in their
hands, the better.
Cheers,
Rafael.
