AHO Reference Surfaces Banks Strait 0.5m 2023: Bathymetry Survey

The AHO Reference Surfaces Banks Strait 0.5m 2023 dataset is a high-resolution bathymetry survey acquired for the Australian Hydrographic Office on 17 Dec 2021. It was created from a contracted national reference survey within Banks Strait to Cape Barren, Tasmania, for calibrating multibeam echosounders. The dataset is provided as a 0.5m resolution, 32-bit floating point GeoTIFF grid in MSL, LAT, and Ellipsoid vertical datums.

Use Cases

• Calibrating multibeam echosounders based on the described reference survey purpose.
• Analyzing seafloor topography based on the high-resolution bathymetric grid.
• Creating or validating nautical charts for the Banks Strait region based on the survey area.
• Conducting marine geological or habitat studies based on detailed seabed elevation data.

Strengths

• High 0.5-meter spatial resolution for detailed bathymetric analysis.
• Survey conducted using specific, named equipment (Kongsberg EM 2040 MkII and EM 2040P).
• Data provided in three vertical datums (MSL, LAT, Ellipsoid) for flexibility.

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 primary application.
