Have you seen the Microsoft Bing Aerial Images? They are taken from a small plane closer to the ground, probably a few hundred feet. They're much nicer than the "satellite" photos (which really are aeiral photos from a high altitude, as far as I know). You can even get views facing different directions. I've attached a picture of a portion of our sugar bush. You can easily pick out individual trees and clearly see the 5-gallon buckets I use.
