AHO Reference Surfaces Adelaide 1m 2023: Bathymetry Survey

AHO Reference Surfaces Adelaide 1m 2023 is a bathymetry survey acquired for the Australian Hydrographic Office from September 4 to September 16, 2020. The surface was created from a contracted national reference survey in Gulf St Vincent, South Australia, for calibrating multibeam echosounders. The dataset consists of separate 1-meter resolution grids for two surveyed sites, exported as 32-bit floating point GeoTIFF files.

Use Cases

• Calibrate multibeam echosounders based on the high-resolution reference bathymetry surfaces.
• Analyze seabed topography in Gulf St Vincent based on the 1-meter resolution bathymetric grids.
• Compare vertical datums (MSL, LAT, Ellipsoid) for hydrographic applications based on the separate grids provided.
• Process bathymetric data using Caris HIPS & SIPS software based on the described methodology.

Strengths

• Survey conducted over a defined period from September 4 to September 16, 2020.
• Data processed using specific industry-standard software (Caris HIPS & SIPS).
• Provides separate grids in three vertical datums (MSL, LAT, Ellipsoid).
• High-resolution 1-meter grids exported as 32-bit floating point GeoTIFFs.

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.
• Row count is unknown, which may limit suitability assessment.
