Galileo NIMS PDS4 Archive

TYPE |
Archive
|
DESCRIPTION |
The original Galileo NIMS archived data were originally publicly available but not in a format that was
readily accessible by the planetary community. This situation precludes the spectral investigation of
surface and atmospheric chemistry and mineralogy for these objects. Several aspects of the NIMS data
archive contribute to this circumstance, including VAX formatted data files (a platform and format
abandoned by the PDS), a challenging radiometric calibration, and the absence of a rigorous
camera/sensor model, and/or data products that have been orthorectified or spatially controlled
relative to SSI observations or more recent Cassini data products (e.g., VIMS). NIMS data are also not
easily accessible by the planetary community. Before this work, NIMS data were only compatible with ISIS2,
a program no longer supported by the USGS and no longer functions on some modern computer operating
systems (e.g., Apple OS X). Galileo NIMS data were also not compatible with mainstream planetary software,
including ENVI/IDL or ISIS3. This effort transitioned the data set to ISIS3 and thereby ISIS3 support
interfaces. The NIMS PDS archive contains tube and g-cube data derived from the EDRs. Considering the
relatively small scope of this effort only the NIMS tube and g-cube product data are the focus of this work.
The objective of this work is to reformat and re-archive the Galileo NIMS data set into a more easily
accessible data format. In order to do this we outlined three basic objectives: Objective 1: Create an
ISIS3 application that reads and converts the NIMS data cubes into native ISIS3 cubes. NIMS data in the
PDS is stored in VAX FLOAT format which is mostly obsolete and not widely used in the community any longer.
This objective would ential adding support for conversion of VAX FLOAT to IEEE FLOAT in ISIS; advantageous
to the pursuit is existing code in ISIS2 that provided a basis for this work. Here we also sought to seek
out problems with the NIMS labels in PDS archive that are not compliant with PDS4 standards. These labels
errors are to then be corrected and exported with properly formed labels to the PDS archive. Objective 2:
Provide the ability to project NIMS tubes using the existing NIMS latitude, longitude tube backplanes.
Objective 3: Derivation of a PDS4 compliant archive of the results of our study and provide it to the PDS
for general distribution. These basic initial steps will make NIMS more user friendly and provide active
support through ISIS help interfaces.
