We don't have ENVI but EI in our country office. However, our colleagues in the field (Africa) have ENVI. I am sending this message on their behalves as they have very limitted internet access. They would like to know the way to batch process in ENVI. Is there a way to go arround IDL programming and rather use a GUI like in EI? COuld you direct then to a turorial? Thank you very much for your answer. Lauriane.
