Roland, the USGS seamless Server has changed itself AGAIN!..........and for the worse, too.
It no longer offers 1/3 arc sec DEM data in GeoTiff formats.
The only formats now offered are Arc Grid and Arc Grid Float.
Any ideas on how to handle this data to get it into TransDEM?

Oh yes, certainly!

See here: viewtopic.php?p=1172#p1172

The next change to .img, announced for spring, has not yet been implemented, though.

Thanks Roland. I'm going to try this out in an hour or so.
Freaking beareucrats over at the USGS can't leave well enough alone......I would think that geotiff would be an easier file format for downloads.
I was in a temporary snit when I got done fidd :evil:

ling with the Server for nearly an hour trying to coax a geotiff download from them.
