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
...

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:
A data store that provides data processed to the AusSeabed standard
A data Catalogue that stores metadata
Connected to the broader AusSeabed Data Hub component infrastructure for seamless delivery to the end user
Meaningfully supported from within their own organisation with a forward commitment to continue for at least 12months.
