The GA Local hub will distribute data using an ISO 19115.3 compliant metadata schema. The metadata outlined below is extracted from the Australian Multibeam Guidelines V2.0 and outlines the metadata required to be provided in order to meet this distribution schema, as well as to support internal data management and processing requirements.
Australian Multibeam Guidelines V 2.0
(Extract section 2.3.1.3 Metadata)
Metadata consistency is an essential aspect of data management and a key step in the move to coordinate a comprehensive national repository of seabed data in the Australian marine estate. The following list of metadata outlines the minimum set to meet ISO 19115.3 standards. The AusSeabed community propose that best efforts are made by collecting and processing institutions to utilise these fields. Appending organisation specific fields is acceptable but such fields should not be used in place of the fields below (Table 6).
