You will find a much better answer than I could give in the GRASS
Imagery Manual (GRASS 4.0) by Harmon & Shapiro.
see section 10 "IMAGERY GROUPS" (p.25)
I have just generated a PDF version and put it up on the CVS server. It
will take a day or so to filter through to the website & mirrors, at
which point it will be available at: (227kb)
If you just can't wait, you can download it directly from the CVS web
