Australian Seabed Bathymetry at 50-Meter Resolution, 2018

Australia's offshore waters, including international waters, are covered by this multibeam bathymetry dataset compiled by Geoscience Australia. It contains all such data held by the agency as of June 2018, gridded at a 50-meter resolution. Source information is provided in a separate vector holdings product, and the data is accessible via a web mapping service.

Use Cases

• Modeling seafloor terrain and geomorphology based on the 50-meter gridded bathymetry data.
• Planning submarine cable or pipeline routes using detailed offshore depth information.
• Conducting marine habitat mapping and ecological studies based on seabed topography.
• Integrating with other marine datasets for regional oceanographic analysis, as the data covers Australia's offshore area.

Strengths

• Compiled from Geoscience Australia's complete multibeam bathymetry holdings as of a specific date (June 2018).
• Provides a consistent 50-meter resolution grid across Australia's offshore area.
• Includes data from international waters, extending the spatial coverage.

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 dataset is explicitly not to be used for navigational purposes, limiting its application scope.
