AHO Reference Surfaces Rottnest 0.5m 2023: Bathymetry Survey Data

A high-resolution bathymetry survey acquired for the Australian Hydrographic Office on 11 December 2022. Separate grids in 0.5m and 2m resolution are provided for two surveyed sites near Rottnest Island, WA, in MSL, LAT, and Ellipsoid vertical datums. The datasets were processed using Caris HIPS & SIPS and exported as 32-bit floating point GeoTIFF grids.

Use Cases

• Calibrate multibeam echosounder systems based on the reference survey data.
• Analyze seabed topography near Rottnest Island based on the 0.5m and 2m resolution bathymetry grids.
• Compare vertical datums (MSL, LAT, Ellipsoid) for hydrographic applications based on the provided separate grids.

Strengths

• Survey conducted with a Kongsberg EM2040P multibeam echosounder, a specific high-precision instrument.
• Data processed using Caris HIPS & SIPS, a specific industry-standard software suite.
• Provides grids in three distinct vertical datums: MSL, LAT, and Ellipsoid.

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.
• Data may reflect geographic bias inherent to the specific survey area near Rottnest Island.
