Viewing Results
Two programs have been developed by Scott Shaffer at JPL/Caltech for viewing SAR images, interferograms and other imagery on X Window System displays. There are Perl scripts included with ROI_pac (dgx.pl and mdx.pl) that will automatically run DGX and MDX, respectively, with the proper parameters to display the ROI_pac results.
The older program DGX, which only works on certain older computer systems with 8-bit color displays, is available from Open Channel Foundation
The newer program MDX, which works on modern 24-bit displays with the X Window System (a.k.a X11), is available for licensing from JPL. It probably won't be released to Open Channel Foundation.
The new MDX license procedure is to access http://download.jpl.nasa.gov, select "Request Software" and follow the instructions provided. Once the JPL Software Release office has the signed license forms, they can give a user name and password to download MDX. The MDX license, like ROI_pac, is free for non-commercial purposes.
The old procedure was to send an email to softwarerelease@jpl.nasa.gov. You will have to fill out some forms, the license goes through an approval process, and then a license is sent out for signature.
Another option is to convert the ROI_pac files to "flat" binary files and load them into GMT or other visualization software. A rmg2grd.pl script that converts files to GMT is available on the ContribSoftware page.
