This is the GIMP(*) PDS plug-in for loading NASA/ESA PDS/EDR format images.

PDS/EDR format is the image format used by NASA Planetary Data System
and by ESA Planetary Science Archives. PDS images from various space
missions are available at http://pds-imaging.jpl.nasa.gov/ and
http://www.rssd.esa.int/index.php?project=PSA

With the PDS plug-in you can load for example images from these missions:
  * Mars Express HRSC
  * 2001 Mars Odyssey THEMIS EDR/RDR-QUB (RGB-loader)
  * Mars Global Surveyor MOC
  * Mars Pathfinder
  * Viking Lander

PDS-files usually have the filename-suffix ".img" or ".imq" if compressed.
Note, that this suffix is also used for other non-PDS file-formats and
if you have another GIMP plugin registered for the same file name suffix just
rename your PDS file to the suffix .imq or .pds to load it with this plugin.

The plug-in will install itself as input filter for files with the following suffixes:
img, imq, edr, pds, red, grn, blu, bb1, bb2, bb3, ir1, ir2, ir3, sun, sur


INSTALLATION:

On Unix systems:
  gimptool-2.0 --install-bin pds

On Mac OS X:
  Download GIMP.app from http://www.gimp.org/downloads/
  Enter in Terminal Window:
    cd Downloads (Downloads is the directory where you have downloaded the file "pds")
    chmod a+rx pds
    cp pds /Applications/GIMP.app/Contents/Resources/lib/gimp/2.0/plug-ins/

On Windows systems:
  Copy the file pds.exe to the plug-ins directory
  of your GIMP installation. For example: "c:\program files (x86)\gimp-2.0\lib\gimp\2.0\plug-ins\"

On Windows systems using the experimental 64bit GIMP:
  Copy the file pds64.exe to the plug-ins directory
  of your GIMP installation. For example: "c:\program files\gimp-2.0\lib\gimp\2.0\plug-ins\"

To build this plug-in from source you need to have GTK, GLIB and
GIMP developer packages installed. Then enter:
  tar xvfz pds-*.tgz
  ./configure
  make install

USAGE:

Select image to load from GIMP File dialog and then you have the choice
depending on the PDS image type:
  * scale the color-range from 16bit to 8 or just strip off the lower byte
  * load the filter frames into one layered image or several single images

For loading Viking Lander images select only one of the .red/.grn/.blu file triplet.
The plug-in then automatically loads the other RGB frames and creates a color image.
