i.atcorr has a rather complex parameter input file, some of it can be simplified by transferring the parameter input to the GRASS GUI i.atcorr dialog box.
it would be beneficial to have a single value input box for:
-
Visibility (overwritten by raster input file “visibility”)
-
if Visibility = 0 then enable value input to Aerosol Optical Depth
-
Elevation (overwritten by raster input file “elevation”)
Combo Boxes:
-
Atmosphere model (combo box with numbers)
-
Sensor code input (Would be nice to have a double combo box, platform first, then sensor band second)
Miscellaneous
Additionally, the central pixel Lat/long can be inferred from computational window + some proj code available in r.sun/i.latlong, or maybe as an input lat/long file (if the image covers a vast area it would be more accurate).
