Dear Grassers,
I need some help to import a Landsat TM image to GRASS. I have this image in BIL format (Band
InterLeaved format) on floppy disks. I really don't know how to start processing these data in
GRASS. I have 4 bands (2, 3, 4 & 5), each two bands in one BIL file (i.e all two files). Also,
I have a header file for every digital file. An alternative way to do it, I am thinking, is using
ER Mapper 4.1 which could handle this format and I have an access to it.
Any clues would be greatly appreciated.
Cheers,

Dear Tarek
I've been bringing a lot of tm images into grass lately and I've
found it easiest just to copy the raw data file into your cell directory then
write a header in cellhd. r.support will give range, histogram, and a
cats file. If you have ERMapper, seperate the band interweave into
seperate files. If you store the ER headers with the files in cell, ER
and GRASS will both be able to access them without any further conversion.
Good luck.
