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:Science_Themes
This is a very simple list of the different science themes for HiRISE.

Field Description Type Null Limits Size Key Default Authority Source
ID This is the unique ID for each Science Theme. The values here should not be assigned by external programs. Instead it can either be ignored, or NULL can be inserted, and the database will automatically assign the next ID. INT(10) unsigned auto_increment Not Null Primary Key db server
VERSION Version number of this record. VARCHAR(255) Not Null db admin
THEME This is the name of the science theme. Acceptable values are "Climate Change", "Eolian Processes", "Fluvial Processes", "Future Exploration/Landing Sites", "Geologic Contacts/Stratigraphy", "Glacial/Periglacial Processes", "Hydrothermal Processes", "Impact Processes", "Landscape Evolution", "Mass Wasting Processes", "Polar Geology", "Seasonal Processes", "Sedimentary/Layering Processes", "Rocks and Regolith", "Composition and Photometry", "Tectonic Processes", "Volcanic Processes", "Other" VARCHAR(64) Not Null db admin
