-------------------------+--------------------------------------------------
Dear grass gis team,
actually I am working with several RapidEye (product Type L3A)
acquisitions, in order to pre-process them for classification. It occurred
to me that in some cases i.atcorr creates a results for the first band
(blue), which seems to be “biased”. I applied i.atcorr on different
machines and used different versions of Grass, but the issue is
persistent.
Grass versions I tried on a Windows7 Professional, 64-bit system:
6.4.4, 7.0.0beta4 and 7.1svn
Input text file values I used:
13
5 25 12.8 52.09413 -10.22328
2
2
0
0.161
-0.253824
-1000
88
For the input imagery and its range a used the min and max values of the
radiance image. As input altitude raster map a 5m DEM was used and for
rescale output the range 0,1.
Please let me know if you need further information!
Many thanks in advance!!
Christoph
