In IMAGINE, convert your images to the LAN format (Erdas 7.x or earlier)
then use i.in.erdas Good luck!

I am using GRASS4.2 for a research project I am
working on in Colorado. My colleagues tend to
use ERDAS alot and I need to convert some images
from ERDAS into GRASS format. I have been trying
to use the i.in.erdas command to do this but with
little success. Most of the images I need to
convert have only 1 band so there is really
little conflict in the conversion.

Whenever I run i.in.erdas I get an error stating
that the ERDAS file cannot be opened. I have a
feeling I have the ERDAS file in the wrong place
or in the wrong format. I have tried a number of
different ways to do this conversion all to know
avail. Thanks for your help.

Thanks,

Tom Meixner
