In a way to accelerate humanitarian mapping what do you think about importing Google’s Open Buildings?
I don’t know yet how it can be done, I’m reading the import guidelines and obviously a quality process has to be planed.
They covered 64% of Africa and generated 516M buildings (called “distinct structures”).
There were numerous examples from active mappers in various African countries -Zambia & Ghana come immediately to mind - who were of the opinion that the data is not of adequate quality. Defects included not processing deep shadow properly; mapping boats or fishing platforms on major lakes, mapping ant hills (termite mounds) as buildings.
It’s quite likely that a single training set was used which probably would not take account of the huge variations across a massive continent.
