Sorry for cross-posting. I would like a confirmation for the following, regarding i.topo.corr:
Is SUN_ELEVATION the requested zenith parameter (by i.topo.corr)? So, given the entry "SUN_ELEVATION = 45.38304417" in the the metadata file "LT51840322011266MOR00_MTL.txt", then, the production of an illumination model requires "zenith=45.38304417". Or is it "zenith = 90 - SUN_ELEVATION", thus it becomes zenith = 90 - 45.38304417 = 44.616956 ?
