[GRASS-user] unexpected i.pansharpen results

[Eric Goddard]

Hi all,

I'm attempting to pansharpen some ikonos imagery using the i.pansharpen
tool in Grass7 on windows 7 installed via OSGeo4W (r54756-478).  The range
for the sharpened red, green, and blue outputs are 0-30, which seems
suspicious given the 16bit range of the input bands. The command I used was:

i.pansharpen.py "sharpen=ihs" "ms3=ik_mss.4 at eric" "ms2=ik_mss.3 at eric"
"ms1=ik_mss.2 at eric" "pan=ik_pan at eric" "output_prefix=ik_ihs"

The input bands are linked via r.external, would that matter?

The output from my test area is below. Any assistance would be greatly
appreciated.[image: Inline image 3]


Thanks,
Eric
