[GRASS-user] i.atcorr with ASTER L1B

[sela]

Well, I finally found out that the 6S algorithm of i.atcorr is not to be
performed only with the header-file information of the Aster-L1B Images. So
I switched to an easier image-based operation (the landsat standard-equation
for the CosT-approach) which was very easy to perform with r.mapcalc.

Greetings
Stefan
