It's apparently a free download. Perhaps someone can try it and report back to us?

I took a brief look at the application.

It works pretty well, it isn't "polished" like a professional application, but certainly functional. Includes access to the Terraserver B&W photos and USGS maps - and downloads very quickly from a High Speed Internet connection.

The quality of the USGS maps is poor compared to the product I work with, Terrain Navigator Pro. We also have color photos on our servers - this appears to be limited to black & white.

Overall, not bad for free. Certainly useful, but not as good as Maptech Terrain Navigator Pro (shameless plug.)
