Hello
i have customized i.atcorr module for satellite sensors of altitude 800kms.It is working properly.i want to find out whether Grass GIS i.atcorr module be customized for Aerial sensor?
Attempted for Aerial sensor which has altitude of 13km but module failed.if the satellite altitude is above 100 km in the icnd file, module is working also if the it is given as positive number also working.If it is below 100km not working by saying"wavelength below 0.25nm." Is there any limitation for the satellite altitude in icnd file.may i know whether i.atcorr supports to Aerial data or not? is anybody used AVIRIS for grass atmospheric correction.

Since it has been developed for satellites I have some doubts.
Attempted for Aerial sensor which has altitude of 13km but module failed.if
the satellite altitude is above 100 km in the icnd file, module is working

not working by saying"wavelength below 0.25nm." Is there any limitation for

You may want to inspect the source code for this:
https://trac.osgeo.org/grass/browser/grass/trunk/imagery/i.atcorr
may i know whether i.atcorr supports to
Aerial data or not? is anybody used AVIRIS for grass atmospheric
correction.
I used it for Landsat, LISS etc so far.
