HiCat Data Dictionary

Catalog: HiRISE
The main HiRISE catalog contains all the information used in operating the HiRISE camera after it is attached to the MRO spacecraft. The information is divided into those related to suggesting, planning, commanding, retrieving, processing, validating, and distributing the observations. The tag that follows an observation through all these catalogs (and from Earth to Mars and back) is the unique Observation_ID. This text representation also forms the core of the product names. The HiRISE catalog also contains ancillary information needed in various uplink and downlink activities, such as the people making image suggestions, MRO project uplink files, SPICE and engineering data, and public image releases.
Table:Observation_Geometry
This table holds shared geometry parameters that apply to an entire observation. Parameters that may be specific to a product will be stored in the proper product table.

Field Description Type Null Limits Size Key Default Authority Source
ID This is the unique identifying ID for each set of geometry parameters. INT(10) auto_increment Not Null Primary Key db server
OBSERVATION_ID The observation id these geometry parameters apply to. VARCHAR(25) Not Null Foreign Key which references Planned_Observations (OBSERVATION_ID) ON DELETE CASCADE unique index HiGeomInit
VERSION The version of these parameters (if needed). VARCHAR(255) Not Null HiGeomInit
BIN1_SCALED_PIXEL_WIDTH This is the BIN 1 scaled pixel width in meters/pixel at the center of the observation. This field is only relevant for EDRs. If an EDR has a binning mode other than 1, then the actual scaled pixel width of the EDR can be calculated by multiplying this value by the value of the binning mode. FLOAT(9) HiGeomInit
