--- Start of Idrisi List message Here is the summary of useful responses to my recent query: Query: I am having a small probelm in importing Landsat 5 data. It has four bands 2, 3, 4, 5. On importing it into Idirisi, four bands are numbered as 1,2,3,4. My questin is: does Idrisi change these no.s in the same sequence? OR how should I relate the old and new band no.?

If this is incorrect, let me know. Otherwise, you are correct, that if it is in one of those formats, it will separate the bands in order, 2,3,4,5. The output names are merely user defined. I hope this helps.

If you use an import module such as BILIDRIS (Band Interleaved by Line), Idrisi imports the band associated with the first line and calls it Band 1. The second band that it finds is named Band 2, and so on. So, as long as you have properly set up the import module the bands will come out in the order in which they were stored. I had a problem with Idrisi mixing up the band numbers on a SPOT image. I later realized that I had neglected to realize that the very first line is the header, so it ended up being my fault. Hope this helps! -Todd __________________________________________________ Todd Albert Byrd Polar Research Center Department of Geography Ohio State University [EMAIL PROTECTED] http://whopper.sbs.ohio-state.edu/grads/talbert/index.html Date: Wed, 02 Aug 2000 14:49:07 +0100 -------------------------------------------------- From: "David R.

I would have thought that the numbering was done in a logical order. -------------------------------------------------- Date: Wed, 02 Aug 2000 07:00:05 -0700 From: Larry Lass <[EMAIL PROTECTED]> Subject: RE: Idrisi-L : Problems with importing satellite data To: "'Vivek Varma'" <[EMAIL PROTECTED]> They are in the same sequence as they are stored in the landsat file.
