I would like to create a medium fidelity terrain database (we have a
hi-fi version for an InfiniteReality due to cliptextures, high geometry
count, etc.) that will run on a Indigo2 Max Impact system. Is
geospecific texture out of the question on a Max Impact or should I go
with geotypical texture?

Also, what are the best sources for imagery? It seems like most of the
ones I have seen are greyscale. Are any color? I can get data from
NIMA, but I want to get the right stuff the first time since it will
probably have to be requested by our sponsor. What are the differences
among Vmap, VPF and DFAD? Is any one better to use or more available
for the world?
