The AusSeabed Bathymetry Compilations Coverage Database from Geoscience Australia contains polygon extents of bathymetry data acquisitions. It is a live, regularly updated resource identifying data from coastal, continental shelf, and deep-sea locations, including the Australian Antarctic Territory. The database aggregates contributions from a wide range of organisations and countries, both inside and outside Australia's marine jurisdiction.
Use Cases
- Map the spatial availability of bathymetric surveys based on published polygon extents.
- Identify data custodians and contact details for bathymetry compilations not held by Geoscience Australia.
- Plan new marine surveys by analyzing existing data coverage across coastal, shelf, and deep-sea locations.
- Monitor the expansion of bathymetric data holdings over time based on the live, augmented database.
Strengths
- Database is live and regularly updated, indicating ongoing maintenance.
- Coverage includes Australia's full marine jurisdiction, including the Australian Antarctic Territory.
- Metadata includes compilation details and contact information for external data holders.
Limitations
- Polygons may not represent true survey extents due to the data gridding process.
- Row count and specific column-level documentation are unknown.
- Data freshness should be verified despite the last update timestamp of 2026-04-20.
