i.atcorr RapidEye band1
|Reported by:||chrisraa||Owned by:|
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:
5 25 12.8 52.09413 -10.22328
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
