#USGS DEM
I suggest looking into Vista Pro. It does all the rendering/etc. all in the
program. It's 3D, and very customizable. You can even do flythru's of the
landscape, panoramic renderings, etc. Lots of stuff. I'm not sure about the
radar images, but I believe it's possible. I haven't tried anything like that
lately. Clint, from VRLI should be popping in to tell more on VP, I believe.
