Hi everyone,
I'm looking for a tool (preferably freeware / opensource) that I can use
to convert USGS DEM data to
vrml elevation grid. Specifically one that can
merge DEM's and select a smaller region to export. Would be most helpful if
it could convert to a lower resolution too.
I realize this is asking a lot. One idea that's been suggested to me is
to use one tool to merge the DEM's, another to convert it to a image w/
colors for elevation, then, having cropped the image, another to convert
from image to DEM again, then DEM to VRML. (I already have some good DEM to
VRML tools, it's the image -> DEM that I don't have).
Regards,
Andrew Jorgensen
