NAME 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.
