Australian Bathymetry and Topography Grid at 0.0025 Degree Resolution

The 2009 bathymetry data were compiled by Geoscience Australia from multibeam and single beam sources. The topography data is based on a revised Australian 0.0025 degree grid, a New Zealand grid, and the 90m SRTM DEM. The dataset covers the topography of Australia and the bathymetry of the adjoining Australian Exclusive Economic Zone.

Use Cases

• Modeling coastal erosion based on combined bathymetry and topography data
• Creating nautical charts based on compiled multibeam and single beam bathymetry
• Analyzing seabed morphology based on satellite-derived bathymetry in shelf areas
• Generating regional elevation models based on the 0.0025 degree resolution grid

Strengths

• Data includes both bathymetry and topography for coastal analysis
• Bathymetry compiled from direct observations like multibeam and digitised chart data
• Topography incorporates multiple authoritative sources including the 90m SRTM DEM

Limitations

• 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
