I don't have any articles. These are just flat binary files.
If you know how many columns and rows (read samples and lines)
and what kind of data you have, these files are read in
about 5 seconds. I've never seen a Data Documentation
page that didn't have this information. (This kind of
information, by the way, is what you put into an ENVI
header file.)

No one warned me that I could get sick on a pilgrimage!
I got some kind of stomach thing that made it, uh,
difficult to travel. It happens. I don't think it was
from drinking bad water, because I was very careful with
that. But, genteel manners are not the norm on the
trail, either. :-)
I'm still taking antibiotics, but I'm mostly recovered,
although still moving slowly and deliberately. It's
harder than I thought to come back to the real world.

Yeah, the world is full of surprises. It's a mystery, really.
Apparently I've been using a map where are the trails lead back
to IDL. :-(
Cheers,
David
P.S. Let's just say I've thought of another reason to
learn how to use a GPS receiver. :-)
