Cairns Bathymetry Survey for Echosounder Calibration, 0.5m Resolution

Cairns, Queensland bathymetry data from a 2020 survey for the Australian Hydrographic Office. The dataset comprises three separate 0.5m resolution grids for surveyed sites, exported as 32-bit floating point GeoTIFFs in MSL, LAT, and Ellipsoid vertical datums. It was acquired using an R2Sonic 2022 multibeam echosounder and processed with Caris HIPS & SIPS software under the Hydroscheme Industry Partnership Program.

Use Cases

• Calibrating multibeam echosounder systems based on the reference survey purpose stated in the description
• Modeling high-resolution seafloor topography based on the 0.5m bathymetric grids
• Comparing vertical datums (MSL, LAT, Ellipsoid) for hydrographic applications based on the separate grids provided
• Assessing coastal bathymetric changes over time when combined with other surveys

Strengths

• High-resolution 0.5m grid cells for detailed seafloor representation
• Provides three separate grids for different vertical datums (MSL, LAT, Ellipsoid)
• Data processed with industry-standard Caris HIPS & SIPS software
• Acquired using a specific R2Sonic 2022 multibeam echosounder system

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
