Hi everyone,
I have some troubles with image fusion through IHS transformation of a
Landsat image. Using d.rgb to display the resulting r,g,b channels gives
completely different colors than the original d.rgb on the 30,20,10
Landsat channels.
On this image:

You see the original d.rgb on the upper left, the panchromatic channel
on the lower left and the result of the IHS transformation on the lower
right.
All channels have a grey.eq color table.
The image
http://geog-pc40.ulb.ac.be/grass/landsat_fusion2.png
shows the same, but zoomed-in, showing that the fusion seems to have
worked (i.e. the resulting image has higher resolution).
Does anybody have an idea of might be the problem ?
Moritz
