DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data Set Overview : An XYZ file contains 3 bands of 32-bit floating point numbers in the Band Sequential order. Alternatively, X, Y and Z may be stored in separate single-band files as a X Component RDR, Y Component RDR and Z Component RDR, respectively. The single component RDRs are implicitly the same as the XYZ file, which is described below. XYZ locations in all coordinate frames for Phoenix are expressed in meters unless otherwise noted. The pixels in an XYZ image are coordinates in 3-D space of the corresponding pixel in the reference image. This reference image is traditionally the left image of a stereo pair, but could be the right image for special products. The geometry of the XYZ image is the same as the geometry of the reference image. This means that for any pixel in the reference image the 3-D position of the viewed point can be obtained from the same pixel location in the XYZ image. The 3-D points can be referenced to any of the Phoenix coordinate systems (specified by DERIVED_IMAGE_PARAMS Group in the PDS label). Most XYZ images will contain holes, or pixels for which no XYZ value exists. These are caused by many factors such as differences in overlap and correlation failures. Holes are indicated by X, Y, and Z all having the same specific value. This value is defined by the MISSING_CONSTANT keyword in the IMAGE object. For the XYZ RDR, this value is (0.0,0.0,0.0), meaning that all three bands must be zero (if only one or two bands are zero, that does not indicate missing data). More information is found in ALEXANDERETAL2008, BOSETAL2007, and KELLERETAL2008. Processing : Phoenix RAC RDRs are considered Level 3 (Calibrated Data equivalent to NASA Level 1-A), Level 4 (Resampled Data equivalent to NASA Level 1-B), or Level 5 (Derived Data equivalent to NASA Level 1-C, 2 or 3). The RDRs are to be reconstructed from Level 2 edited data, and are to be assembled into complete images that may include radiometric and/or geometric correction. Phoenix RAC instrument EDRs and RDRs will be generated by JPL's Multimission Instrument Processing Laboratory (MIPL) as part of the OPGS subsystem of the Phoenix GDS. RDRs will also be generated by the RAC science instrument team at the SOC facility at the University of Arizona, as well as at its home institution, Texas A&M. RDR data products will be generated by, but not limited to, MIPL using the Mars Suite of VICAR image processing software at JPL, and the RAC science instrument team using TAMCAL and RACCAL software at the SOC facility at the University of Arizona and at the team's home institution at Texas A&M Univerisity. The RDRs produced will be 'processed' data. The input will be one or more Camera EDR or RDR data products and the output will be formatted according to the data product SIS [ALEXANDERETAL2008]. Additional meta-data may be added by the software to the PDS label. Data : RDR products generated by MIPL will have a VICAR label wrapped by a PDS label, and their structure can include the optional EOL label after the binary data. RDR products not generated by MIPL may contain only a PDS label. Or, RDR products conforming to a standard other than PDS, such as JPEG compressed or certain Terrain products, are acceptable without a PDS header during mission operations, but may not be archivable. The RDR data product is comprised of radiometrically decalibrated and/or camera model corrected and/or geometrically altered versions of the raw camera data, in both single and multi-frame (mosaic) form. Most RDR data products will have PDS labels, or if generated by MIPL (OPGS), dual PDS/VICAR labels. Non-labeled RDRs include JPEG compressed products and the Terrain products. Software : The MIPL Mars Program Suite was used to generate these RDRs. Media/Format : The data set will initially be delivered and kept online. Upon Mission completion, the RAC Operations RDRs will be delivered to PDS on DVD.
