This would be killer. There are some kml overlays for BLM and NFS land, but imagine an "access" layer that was something like "public free access", public access with admission fee, private but open to the public (like retail), and private.

Lacking this kind of information could quite literally be a killer given the propensity of some in the US to shoot first.

I think the improvement goes beyond greenery information, although the latter is the most obvious. If looking carefully, one can also spot a significant improvement regarding water surfaces. Those are useful reference points. Granted, they are often outside of where people are living, but this is part of a process making the map more accurate and probably more automated than before, which is a laudable thing. In my opinion the new map is also more pleasant to the eye and all in all, I would rather use it over the old one.

Have a look at OpenStreetMap :D
