Hi all,

Which command can do this？ Although i.atcorr does include “Pre-defined MODIS bands: 42 - 48”, the “A. Geometrical conditions” does’t include MODIS sensor.

Best Regards,

In fact, it is missing from Geom.Cond.cpp. The question is: does it
behave like Landsat or like another already implemented satellite? The
code comes from the 6S/NASA software where is must be lacking, too.

They have a newer version here: http://6s.ltdri.org/
which I didn't try yet.
