A 2009 compilation of bathymetry and topography grids for Australia and its Exclusive Economic Zone. The data integrates multibeam, single beam, digitised chart, and satellite-derived sources, with a 0.0025-degree resolution grid where direct observations are dense. The topographic component is based on revised Australian and New Zealand grids and a 90m SRTM DEM.
Use Cases
- Modeling coastal erosion and inundation based on integrated bathymetry and topography data.
- Creating nautical charts and maritime safety maps based on compiled multibeam and chart data.
- Analyzing seabed morphology for habitat mapping based on high-resolution bathymetric grids.
- Generating 3D visualizations of the Australian continental shelf based on the combined topographic and bathymetric surface.
Strengths
- Integrates multiple authoritative sources including Geoscience Australia compilations and ETOPO global models.
- Provides a high-resolution (0.0025-degree) grid where direct bathymetric observations are sufficiently dense.
- Covers a defined geographic area encompassing Australia's onshore topography and adjoining Exclusive Economic Zone.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- The area selected excludes data from Australia's marine jurisdiction offshore from the Territory of Heard and McDonald Islands and the Australian Antarctic Territory.
