Grass 5.0b7 + NVIS2.2 = WOW!

[Eric Mitchell]

I finally got NVIZ running on my machine here, and I 
just wanted to say, WOW!  You all have done a lot of 
excellent work in getting grass together, and NVIZ is 
a great visualization tool.  I'd consider myself a 
"recreational" grass user, primarily plotting handheld
GPS data against topo maps just to see where the trails
go.  I just plotted a trail (highway 160 in Colorado, 
actually) using nviz, and my jaw just dropped.  Thanks
to all those who have helped to get this together.

I have a question, though.  For raster format elevation 
data, I'm working off of 7.5min USGS dems.  Is there an
easy way to merge neighboring raster maps without losing
too much resolution?  I've tried using the CELL driver, 
but the resulting raster data loses a lot of the contour
of the original data.  Is there a better method available?

P.S. I'll take beta7 for another spin on the SGI when I 
get the chance.
