Brief description
Please note that this public coverage does not include information that has been provided to Geoscience Australia under a Restricted and Exclusive license. However, the additional restricted information is used during the computation of Australian marine jurisdiction’s Percent Mapped assessment.
Lineage
Maintenance and Update Frequency: continualThe AusSeabed 'Bathymetry Acquisitions Coverage (Dynamic)' is compiled from:
- International data acquirers travelling through Australia's EEZ
- Domestic data acquirers published on the AusSeabed Marine Data Portal made up of:
- computed footprints of individual Geoscience Australia bathymetry survey/acquisitions
- computed footprints of Investigator and Southern Surveyor Survey/Acquisitions supplied by CSIRO
- computed footprints of Aurora Australis and Nuyina Survey/Acquisitions supplied by the Australian Antarctic Division (AAD)
- computed footprints from AusSeabed data contributors (Australian Universities, State Authorities and other contributors)
- Additionally, coverage indexes are also sourced from:
- The Australian Institute of Marine Science (AIMS), the Australian Hydrographic Office (AHO), the WA Dept of Transport (WADoT), WA Landgate, City of Gold Coast, and various Port Authorities.

Data is often received as Shapefiles or ESRI File Geodatabases or generated from a Raster to Vector transformation of bathymetry grids (geoTIFFs).
These are compiled, cleaned, simplified and validated using ESRI and OGC geometry tools along with key identifiying metadata attributes. As a minimum the following attributes are collated.
