Multibeam Bathymetry of Australia's Offshore Waters, 50m Grid 2018

June 2018 holdings of multibeam bathymetry data for Australia's offshore area, including international waters, compiled and gridded at 50-meter resolution by Geoscience Australia. The dataset is accessible via a web mapping service on Geoscience Australia's Marine data portal and is not intended for navigational purposes. Source metadata is provided in the associated AusSeabed Bathymetry Holdings vector product.

Use Cases

• Modeling seafloor topography based on 50-meter gridded bathymetry data
• Analyzing offshore geological features based on compiled multibeam data holdings
• Integrating bathymetric data for marine spatial planning based on the defined offshore area coverage

Strengths

• Gridded at a consistent 50-meter resolution
• Covers Australia's offshore area including international waters
• Compiled from Geoscience Australia's holdings as of a specific date (June 2018)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Freshness should be verified as the snapshot is from 2018
