AHO Reference Surfaces Banks Strait 0.5m 2023: Bathymetry Survey for Sensor Calibration

Banks Strait to Cape Barren, Tasmania, is covered by a high-resolution bathymetric survey. The Australian Hydrographic Office acquired this data on 17 December 2021 using Kongsberg multibeam echosounders. It provides a 0.5-meter resolution GeoTIFF grid in multiple vertical datums for calibrating hydrographic equipment.

Use Cases

• Calibrate multibeam echosounder systems based on the described reference surface data.
• Analyze seafloor topography in Banks Strait based on the 0.5-meter resolution bathymetric grid.
• Compare vertical datums (MSL, LAT, Ellipsoid) for a specific survey area based on the provided grids.

Strengths

• High 0.5-meter spatial resolution for detailed seafloor mapping.
• Data provided in three vertical datums (MSL, LAT, Ellipsoid) for flexibility.
• Acquired using specific, professional-grade equipment (Kongsberg EM 2040 MkII and EM 2040P).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and column-level documentation are absent; field semantics must be inferred after download.
