Dear all, I want to read SARscape-related products, e.g. coherence image, by IDL. Except for *.hdr file, SARscape product also includes *.sml file to describe the meta information. How can I import and export such product file in a way of keeping *.hdr and *.sml files the same format? Of course, I can enforce it some ways, says "ENVI->File->Export to IDL Variable". However, I will lose the *sml file when executing "ENVI->File->Import from IDL Variable". Not only this, the *.hdr file would be changed as well. I had tried to search for some suitable routines on internet as well as Help context, but nothing solvable to this issue can be found. Best regards, Chia-Hsiang Yang
