[comp.graphics] Query on Geographical Information Systems

   I am starting to get involved in a project where I have to generate a large
amount of (hopefully) realistic terrain for an image generator for visual
flight simulation.  Since this is research we don't want to be tied to real-
world data, but instead want to create the terrain according to the needs of
the particular experiment.  An interactive 3D terrain modeller which could
handle databases with millions of polygons would be perfect.  Can anyone
suggest some possibilities?  Are there any news groups dedicated to GIS?
Does any sort of terrain description macro language exist?  Does anyone have
any good references in these areas?

Thanks,

Jonathan
