Merging DEM's

[aanderson =]

I have had some success at reading 7.5 min USGS DEMS, using
Sol Katz's routines which I had to modify to fix some alignment
problems when joining maps together. I have also been able to
use the DLG's from the same source. 

Have you tried Katz's stuff?

try:

http://ftp.blm.gov/pub/gis/sdts/dem/old/sdts2dem.tgz

which also use the fips123 lib at

http://sdts.er.usgs.gov/pub/sdts/software/fips123/fips123*.gz

Good luck
