AHO Reference Surfaces Banks Strait 0.5m 2023: Bathymetry Survey

The Banks Strait Reference Surfaces bathymetry survey was acquired for the Australian Hydrographic Office on 17 December 2021. It was created from a contracted national reference survey within Banks Strait to Cape Barren, Tasmania, for calibrating multibeam echosounders. The dataset includes a 0.5-meter resolution grid exported as a 32-bit floating point GeoTIFF.

Use Cases

• Calibrating multibeam echosounder systems based on the high-resolution reference surface.
• Analyzing seafloor topography based on the 0.5-meter resolution bathymetric grid.
• Referencing vertical datums (MSL, LAT, Ellipsoid) for marine charting and research.

Strengths

• High-resolution 0.5-meter grid derived from survey data.
• Survey conducted using specific Kongsberg EM 2040 MkII and EM 2040P equipment.
• Data processed using QPS Qimera software.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is explicitly not to be used for navigational purposes.
