Does anyone know where any other DEM data can be found? The link on Bob Crispin's page to the USGS DEM data isn't valid anymore. There are NO files at the ftp site. I looked around today and all data directories are empty at ftp://edcftp.cr.usgs.gov/pub/data/DEM/* . Thanks! Mark D. Krutz MTL Systems, Inc. mkrutz@mtlva.com (703)359-2510 x29
