I have 3 maps from there. The web site is gone or taken over.

POV correctly.

I have use the DEM for earth. Its been awhile.
There was a conversion program that make an image map from Dem data. I

I put a few images in the BPs Images. I had them scattered all over my
hard drive. While I was going through the old Mars POVs I found better
ways of doing things. They where wrote in 2005?!
