I never said you could get any of those things from aerial imagery.

I'm not attempting to map everything to the nth degree, there is a lot
of things not mapped in Australia, at this point of time there is a
large number of newly developed areas and even fewer people mapping so
I'm trying to do my bit by at least trying to work out the most
efficient way to collect the most amount of information with the least
amount of people in the least amount of time.
