Australia Multibeam Bathymetry Gridded at 50-Meter Resolution

Geoscience Australia compiled all multibeam bathymetry data held within the offshore area of Australia, including international waters, as of June 2018. The data is gridded at a 50-meter resolution. Source information is available in a separate vector product, and the dataset is accessible via a web mapping service on the Marine data portal.

Use Cases

• Map seabed topography based on the 50-meter gridded bathymetry data.
• Analyze offshore geological features based on the compiled multibeam holdings.
• Conduct marine spatial planning based on the detailed bathymetric coverage of Australia's offshore area.

Strengths

• Compiles all multibeam bathymetry data held by Geoscience Australia as of a specific date (June 2018).
• Provides a consistent 50-meter grid resolution across the compiled area.
• Covers Australia's offshore area, including international waters.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is explicitly not to be used for navigational purposes.
