Thanks to everyone with the previous response for creating a composite
image. i.composite worked the best, however is still not completely
working for me. I would say there was a problem with the file, but we
are able to process it with another program, just takes hours to
The problem that I am having is that there doesn't seem to be much color
variation. How do I explain this. Example, the United States
background color is a bright yellow. It should be a softer yellow, with
different shades. Not happening. I have tried a variety of color
levels, from 2 (min) to 6/7 (for 256 colors) and all the way to 500.
None have worked. Am I doing something wrong? One question, how do you
know which file is red/green/blue? It has come as an erdas .img file.
I am assuming that xrast.1 is red, xrast.2 is green, xrast.3 is blue.
Thanks in advance for any hints. I am sure it is user error...but for
the life of me, cannot get it to work..
