Cairns Bathymetry Survey for Multibeam Calibration, 0.5m Resolution

AHO Reference Surfaces Cairns 0.5m 2023 provides high-resolution bathymetry data for calibrating multibeam echosounders. The Australian Hydrographic Office acquired the survey on 27 May 2020, processed it using Caris HIPS & SIPS, and exported it as a 0.5m resolution GeoTIFF grid. Separate grids are provided for three surveyed sites in MSL, LAT, and Ellipsoid vertical datums.

Use Cases

• Calibrating multibeam echosounders based on the high-resolution reference surfaces.
• Analyzing seabed topography in Cairns, Queensland based on the surveyed sites.
• Comparing bathymetric measurements across different vertical datums (MSL, LAT, Ellipsoid).

Strengths

• High-resolution 0.5m grid derived from a national reference survey.
• Data processed using specialized hydrographic software (Caris HIPS & SIPS).
• Provides three separate grids for three surveyed sites.

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.
