The data from the AISA+ hyper-spectral scanner was first processed using CaliGeo (using default parameters, except that we
used "external NAV-files"). CaliGeo, starting from version 4, runs as a part in the ENVI+IDL software environment. It runs
as a separate software package under the ENVI software package, sold by Research Systems Inc.
In short, CaliGeo is used to do all the radiometric corrections and to rectify and georeference AISA data.
