Jim, it depends on how you define "much". It certainly gave us a "feel" for what we would encounter, more so than any topo map could. It definitely didn't show us every bump in the trail but it did give us a good idea of the general vegetation or lack thereof. And we were fully aware that we were not looking at a real time image. But it is much more real time than many U.S.G.S. topo maps which have not been revised for many years.

Considering the cost ($00.00) and the fun factor I would recommend GE to anyone.

As a side note, one of my other hobbies is locating old military plane wrecks/crash sites. I have learned lots of ways to locates these sites using images from GE.
