Marine Bathymetry Data Collection from Multiple Acoustic and Satellite Sources

Bathymetric data for mapping the sea floor, collected via multiple methods including satellite altimetry, singlebeam echosounders, multibeam echosounders, and airborne laser (LADS). The dataset is a collection of data acquired by Geoscience Australia and other government and non-government agencies. It was last updated on 2026-04-30.

Use Cases

• Producing low-resolution seafloor feature maps over large areas based on satellite altimetry data.
• Identifying general sea floor patterns or fish schools using singlebeam echosounder line data.
• Creating high-resolution seafloor models with sub-meter accuracy from multibeam or LADS swath data.

Strengths

• Integrates data from multiple collection methods, including satellite, singlebeam, multibeam, and LADS.
• Includes high-resolution data with accuracy down to better than one metre from multibeam and LADS sources.
• Sourced from a national geological survey (Geoscience Australia) and other agencies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific spatial or temporal coverage are unknown, which may limit suitability assessment.
• Data is provided in HTML format, which likely contains metadata rather than the raw data files themselves.
