Hi, Geoffrey:
I will start from the end:
It's not only useful to get the local OSM community involved; it's the
most important.
What I mean is that it will always be much better to rely on local
people with local knowledge than in a Spanish guy like me who, although
trying to do my best, I've never been in Uganda before (although I have
been in quite a number of African countries, similar to Uganda, and
mapped a lot in many other). I'd wish to visit Uganda soon, by the way ;)
Yes. Educational facilities in big cities like Kampala are very
difficult to double check against imagery. It would be really nice if
mappers from Kampala would like to check the UBOS nodes inside Kampala,
so we can import most of the nodes there, and with the highest quality.
In that case, we could even divide the import, leaving the Kampala nodes
for local mappers to import and check on the ground. Everything is possible!
Normally, in previous similar imports, we asked for school road access
tracing, for adding facilities buildings and to add the village name if
not present. But this time the number of nodes is very big (24,587), so
I thought it would be better to first focus only in importing the nodes,
and then, afterwards, add more info. Road access and buildings is one
type, but using the school info to add village names to the map will be
a very important step forward, specially for those "black" areas of the
map that you talk about.
The quality of the health facilities is not good enough in what respect
to geolocation, so we will need a different approach to get the most of
that dataset.
Cheers,
Rafael.
