Hello Michael and others:
I have been trying to get DEMs that have been ftp'd into grass by
using dd if=old.dem ibs=512 obs=1024 conv=block of=new.dem
and then m.dem.extract. From the chunk of message included
I guess there's a better way (I hope so since my idea didn't work).
BUT, I read through the man pages for dd and don't see how the heck
you deal with the crazy DEM format by simply using "approriate parameters"
could you please elaborate a bit on this.
(c) To extract the data don't use GRASS programs. Use dd with
approriate parameters to extract each dem into a rater file
directly. Then use r.support to create an appropriate header file
(by hand) - g.region will be of no use to dd. The issues you need
to look into are
Thanks for your time.
