I have a question about the i.tape.mss utility.
[details deleted]
I have two 9 track MSS tapes, one in a band sequential format (1989)
the other from 1975, in the "MSS X format"...The Question....
The 1975 MSS X, format will not read... the message indicates that "this may
not be an MSS file". Is there a limitation in this utility? or am I
missing something?
The grass 4.1 i.tape.mss utility only deals with BIL formatted tapes, and
not the pre-1979 X-format tapes. Scenes in X-format consist of 4 vertical
swaths, each swath being a file with all 4 channels interleaved in scan
lines by pixel pair. Each file has some header info, as does each scan
line. A while back I kludged together a routine written in the IDL graphics
language to demultiplex the swaths into the constituent image bands, and
then join the swaths. It was just a quick hack, but if there is any
interest I'll post it (if I can find it!).
