Import PDS formatted HiRISE RDR image cube into Isis format cube
Description
This program will import a PDS formatted HiRISE RDR image into an Isis
cube. The normal generic application is pds2isis, however HiRISE
images require special consideration. These considerations are based upon
requirements placed on the process of converting original HiRISE ISIS
products into PDS archive format and back again. The HiRISE team requires
a certain level of preservation so that science analysis on the PDS
archived product, particularly in the ISIS system, is not compromised.
One consequence of the PDS storage requirements is the conversion of
ISIS data to unsigned 16-bit integers. This data storage type is not
support inherently in the ISIS system, but this application converts
it to the best data representation possible - 32-bit floating point
values. Comparisons of the conversion process falls within acceptable
precision loss (approximately 1.0E-6).
Much of what this program does is ensure labels are properly copied
and translated from PDS archival form that is consistant and highly
comparable to the original ISIS product. The strictest requirement is
label integrity which applies mainly to geometric datum contained in
the ISIS labels. The goal is to ensure geometric behavior is within
acceptable limits of the original product.

The following modifications where made to more closely adhere to the
orginal ISIS himos source: map the PDS Archive group back to the
ISIS Mosaic group; PDS NULL values of -9998 are mapped back to
ISIS Null; order of the groups are written in the same order as the
ISIS input file; Target radius values are updated for the
Equirectangular projection only such that the existing
(EquatorialRadius) radius value is copied to the CenterLatitudeRadius
keyword and the actual NAIF radii replace EquatorialRadius and
PolarRadius values if it is a valid NAIF target; the order of the
values in keywords cpmmTdiFlag, cpmmSummingFlag and
SpecialProcessingFlag are reordered according to CPMM order as it is
in the original source; and added a bit more documentation.

Description
Use this parameter to select the HiRISE RDR filename. This
file must contain the PDS labels. This file must have been generated
by the ISIS hirdrgen application. These files are assumed to
be projected products.
