Polygon extents of bathymetry data acquisitions spanning coastal, continental shelf, and deep sea locations, including the Australian Antarctic Territory. The live database is updated regularly by Geoscience Australia and AusSeabed collaborators via the AusSeabed Marine Data Portal. Each polygon contains metadata describing compilation details generated from multiple surveys by various organisations.
Use Cases
- Map bathymetric data availability based on polygon extents and metadata attributes.
- Identify data sources and contacts for specific marine regions based on the coverage database.
- Analyze survey compilation footprints for planning new data acquisitions based on existing coverage.
Strengths
- Live database updated regularly as new coverage details are supplied.
- Coverage includes Australia's full marine jurisdiction, extending to the Australian Antarctic Territory.
- Compilations are generated from multiple surveys by a wide range of organisations, suggesting diverse sources.
Limitations
- Polygons may not represent true survey extents due to the data gridding process.
- Row count and column-level documentation are absent, limiting suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
