Australian topography and bathymetry data for the Australian Exclusive Economic Zone, excluding offshore territories. The 2009 bathymetry data were compiled by Geoscience Australia from multibeam, single beam, and satellite-derived sources, while onshore topography is based on revised Australian and New Zealand grids and SRTM DEM.
Use Cases
- Model coastal erosion and inundation based on integrated bathymetry and topography.
- Analyze seafloor geomorphology based on multibeam and single beam survey data.
- Create marine habitat maps based on high-resolution bathymetric observations.
- Conduct continental shelf studies based on the defined Australian Exclusive Economic Zone area.
Strengths
- Integrates bathymetry and topography for a continuous land-sea model.
- Uses high-resolution (0.0025 degree) grids where direct observations are dense.
- Compiled by Geoscience Australia from multiple authoritative sources including multibeam surveys and SRTM DEM.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- The area selected does not include data from Australia's marine jurisdiction offshore from the Territory of Heard and McDonald Islands and the Australian Antarctic Territory.
