SM55: 50m Resolution Multibeam Bathymetry Grid of Australia

Geoscience Australia's multibeam data within tile SM55, gridded to a 50-meter resolution. Some deeper data has been interpolated within the mapped area. The data was held as of August 2012 and is distributed by the Australian Ocean Data Network.

Use Cases

• Generate seafloor terrain models based on the 50-meter gridded bathymetry.
• Analyze underwater geological features based on the multibeam survey data.
• Support marine navigation and habitat mapping based on the interpolated deeper data.
• Conduct coastal geomorphology studies based on the specified Australian area coverage.

Strengths

• Data is gridded to a consistent 50-meter resolution.
• Includes interpolated deeper data within the mapped area.
• Sourced from Geoscience Australia, a national geoscience agency.

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.
• Data snapshot is from August 2012; temporal coverage is not ongoing.
