Hi Alex,

Having personally seen Addis Ababa changing so much between 2007 and 2019,
I think that sounds like a good strategy.

Regarding crowdsourced importing tools, HOTOSM tasking manager coupled to
the OSMSharp service developed by Ben Abelshausen (and recently added to
HOTOSM) works well for reviewing multiple objects within a bbox. It easily
loads the objects for review in a separate layer. Alternatively, for
checking one object at a time, MapRoulette is a great option.
