<br><font size=2 face="sans-serif">We have written a PDS plug-in for GDAL
but have not released it because there are still questions about supporting
planetary coordinate systems. And even though PDS is a "standard"
there are many differences in the various catalogs because it supports
so many different instruments. You also have to be a little careful because
there are also many inconsistencies with the labels (especially when it
comes to the registration parameters). You will also find that most PDS
images are in their original raw (unprojected) space. This means you really
need speciality software like USGS's ISIS or JPL's VICAR to process it
first.</font>
<br>
<br><font size=2 face="sans-serif">So to get users started with PDS images
we have a released a very simple PERL script to read map projected PDS
images and write out various GIS headers. The easiest for GDAL is to use
the "-p" options when using the pds2world.pl script, which generates
a PCI Aux header file. The *.aux file created can then be read and converted
by GDAL.</font>
