Description
A 0.5m resolution bathymetry grid was created for the Australian Hydrographic Office from a survey conducted between 25-26 September 2020. The surface covers an area between Gantheaume Point and Talboys Rock, Broome, Western Australia, and is provided in MSL, LAT, and Ellipsoid vertical datums. Data was acquired using a Kongsberg EM 2040D multibeam echosounder and processed with Caris HIPS & SIPS software.
Use Cases
Calibrating multibeam echosounder systems based on the high-resolution reference surface.
Analyzing seafloor morphology and topography based on the 0.5m resolution bathymetric grid.
Comparing vertical datums (MSL, LAT, Ellipsoid) for geospatial accuracy in marine applications.
Strengths
High-resolution 0.5m grid derived from a dedicated national reference survey.
Data provided in three vertical datums (MSL, LAT, Ellipsoid) for flexibility.
Acquired using a specific, professional-grade sensor (Kongsberg EM 2040D).
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.
