Hello from off-list,

I'm trying to convert from DEM to a VRML2.0 node called ElevationGrid, and
I'm looking for information on the DEM header.

As you can see below, I was given this address by Tim Glover.

Thanks,

Dan

    Try bouncing this question off the grass serlist (Grass is a public
    domain GIS developed by the US Army)  I've followed that list for
    several months and they do conversions from DEMs all the time -- they
    can probably explain the headers if anyone can!


    address is:
    grassu-list at pandora.cecer.army.mil

Speaking of GIS and large scale stuff,

Does anyone have a DEM -> ElevationGrid converter?  If not, I'd like to
try my hand at this converter-writin' game.  It looks to be pretty easy
but I have not been able to figure out all the header stuff in the DEM
files I have from USGS, and I was disappointed to find no entry for DEM in
the O'Reilley graphics formats book.  It's also unfortunately the kind of
thing that is very hard to find information on- all my searches were quite
noisy.
