k...man, it's a freakin awesome program. I have been playing around with it a bit. If you want more realistic vertical relief go to view and change vertical exaggeration to 1.5x instead of 3x. 0x is flat, I find that 1.5x is realistic. If you want to check out the mountains use the landstat7 visible color. uuuhhhhmmm...no wait....even better, try lanstat7 psuedo...even better it even shows logging scars. The urban areas one doesn't seem to be working yet.
Keep in mind only zoom in a bit at a time and let everything load up then zoom in more, let it load up ect ect. It takes a while to load properly and I found that if it doesn't work then zoom back out and try again.
Thanks for the link Dru.
