Annex C describes a number of tools to visualize the output of Doris. The parameter files, log file, etc. can be viewed with any standard editor. For this, the run script utility can also be used, customized by setting the PAGER and EDITOR environment variables.
The data output are binary files, which can be visualized with standard software on your system, e.g., Khoros, Matlab (tip: try spinmap), etc.
The utility cpxfiddle (c++ in SARtools archive) can, amongst other things, generate SUNraster files of the phase, magnitude, and magnitude+phase with a colormap of your liking (use, e.g., "xv" or "display" to view/print.) This seems to be one of the fastest ways to see the results. See also the PREVIEW card.
The utility cpx2ps (csh script) can generate postscript code from complex files for the magnitude or phase. (use gv or ghostview to view/print.) This utility uses the GMT package. (Tip: generate 2 m postscript files, with -Z option, and view this enlarged interferogram with gv.)
If someone want to develop a Motif/Lesstif X windows application that would be very welcome. We have experimented with these things, but no time to implement it in a robust way.
A tip might be to use X utilities like xmag or xlupe to zoom in on the visualized files.
