Camera will definitely make a huge difference.
It could also be that in your example conventional aerial cameras are used.. mounted on the planes.
I am pretty sure nearmap.com doesn't use satellites for their maps.
Also, it's not the same thing to have 100kg camera on the satellite orbiting Earth, and the one orbiting Moon (the latter one requires much more effort to bring it to the destination .. and considering recent NASA cuts... you know what I mean)
