SUBMISSION | A collection of Acquisitions submitted to AusSeabed as a package of data |
ACQUISITION | Data Acquisition from one or more Platforms and Sensors, usually covering over a shorter defined period of time and a specific geographical extent. The acquired data is used to generate multiple products and resolutions and can be combined with others to create a compilation |
ACQUISITION CODE | This is generally considered the SURVEY ID. An identifier provider from the data acquirer |
COMPILATION | A combination of distinct Acquisitions from multiple sources, platforms and sensors that is often covers a considerable time period and geogrpahical extent. |
CRS | Coordinate Reference System |
Contributing Data Partner | A contributing data partner is an organisation that has agreed to assign custodianship for a data product to GA, as an implemented AusSeabed Data Hub. |
Contributing Hub | A Contributing Hub is:
|
DOI | Persistent Digital Object Identifier (https://www.doi.org ) |
GEOMETRY | The shape of a feature defined by a type and coordinate pairs. e.g a Point, Line, Polygon |
INSTRUMENT | A term to describe different categories |
L0 | An AusSeabed term to categorise a data level relating to Raw data, derived directly from Sensors |
L2 | An AusSeabed term to categorise a data level relating to Processed data |
L3 | An AusSeabed term to categorise a data level relating to generated products often Gridded. |
PLATFORM | Platform is the structure or vehicles on which instruments are mounted. (Ground based, Airborne, Satellite, Water based) |
SHAPEFILE | |
SENSOR | The specific device that senses and captures measurements |
UTC | Coordinated Universal Time – primary time standard |
