For some reason (which I am investigating) the gpd and mpp
files you downloaded from the web page were in DOS
format. In other words, they contained an extra ^M character
on each line. I ran the UNIX command dos2unix on both files,
and then they worked as they were suppose to work.
I'll see what I can do to get the files updated on the web page.
Cheers,
David

OK, I think the most *likely* answer is that the gpd file
is "corrupted" in the sense that it is missing (or maybe
has too many) ^M line control characters. The mapx
program has been known to choke under these conditions
and issue exactly this kind of "unknown projection" error.
This kind of corruption can be caused by improper settings
when doing an ftp of the file from one machine to another,
or by e-mailing the file, etc.
The easiest way to see these "problem" line endings
is to open the file in an emacs editor. Perhaps it is
best to download a "valid" gpd file from the NSIDC web
page and see what the endings are suppose to look like,
then make sure the endings of your gpd file match.
Let me know.
Cheers,
David

Yes.

Yes, Linux 2.6.16.46-0.12-smp (a rather old SuSE system)

Cylindrical Equal-Area sort of worked, but gave a different error
(some 250 m / 1 km mixup, it seems).

And the mapx is recent? Installed at the same time
you installed ms2gt?
Also, I assume some kind of 32-bit OS?
Have to tried a different projection, just to see if
you can get something to work?
I have to do some car shuffling this morning, but
off to work soon.
Cheers,
David

Thanks for investigating. I didn't even notice that. Had I created the
files myself, they would have been proper UNIX files. Still no luck
though, but at least we're getting past stage one.
Best,
Maarten
