AHO Reference Surfaces Rottnest 0.5m 2023: Bathymetry Survey Data

A bathymetry survey acquired for the Australian Hydrographic Office on 11 December 2022 created this reference surface. Separate grids in 0.5m and 2m resolution are provided for two surveyed sites near Rottnest Island, Western Australia, in MSL, LAT, and Ellipsoid vertical datums. The datasets were exported as 32-bit floating point GeoTIFF grids.

Use Cases

• Calibrate multibeam echosounders based on the high-resolution reference surface.
• Analyze seafloor topography based on 0.5m and 2m resolution bathymetry grids.
• Compare vertical datums based on the provided MSL, LAT, and Ellipsoid versions.

Strengths

• High-resolution 0.5m and 2m grids provide detailed bathymetric data.
• Data is provided in three standard vertical datums (MSL, LAT, Ellipsoid).
• Survey was conducted using a Kongsberg EM2040P multibeam echosounder.

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.
