Part of the site for SoftSource, a CAD (Computer Aided Design) developer, the five Topographical Pictures here were rendered using Drawing eXchange Engine, an Autocad design tool. These full-color images of the Grand Canyon, Mount Ranier and Mount Baker are available in GIF format. The digital elevation information from the US Geological Survey used to produce these pictures is FTP-able from this site.
