Terrain display

[lazear at gateway.mitre.org (Walt Lazear)]

What I'm looking for is a straightforward way to input the
contours from a topological map of an area, then display these on
a Sparc-2 class of machine in such a way as to be able to look 
at the terrain from different vantagepoints.  Rapid repositioning
of the viewpoint (i.e., "flying") is not necessary.  Is there such
a system or approach to doing this that you know of? 

Is Geomview suitable for at least the display aspect of my quest?
The Unix Review article on Geomview mentioned SGI Iris as the current
platform.  When will Geomview be available on a Sun Sparc-2?

Thanks for any help in this area.
