the latest "Cray Channels" magazine (v6, #1) has an article on work
at Lawrence Livermore with detailed terrain info.  They're working
on a fast-resonse system in case of radioactive leaks, strangely
enough.  They mention 2 data bases:  Defense Mapping Agency, resolution
of 65 meters; and a modified version of same, resolution 500 m.

They produce very pretty ray-traced 3-d views of the terrain using
(naturally) a Cray machine.

The authors are Patrick Weidhaas and Hoyt Walker.
