Broome Bathymetry Survey Grids In 0.5 Meter Resolution

25 Sep 2020 - 26 Sep 2020 bathymetry survey data from the Australian Hydrographic Office. The surface was created from a contracted national reference survey between Gantheaume Point and Talboys Rock, Broome WA, for calibrating multibeam echosounders. It provides 0.5m resolution grids in MSL, LAT, and Ellipsoid vertical datum, exported as 32-bit floating point GeoTIFF files.

Use Cases

• Calibrate multibeam echosounder systems using the high-resolution 0.5m bathymetry grids as a reference surface.
• Analyze seafloor topography by comparing the MSL, LAT, and Ellipsoid vertical datum grids for the surveyed site.
• Process bathymetric data using Caris HIPS & SIPS software workflows with the provided GeoTIFF grids.
• Assess survey area coverage and data quality for the region between Gantheaume Point and Talboys Rock.

Strengths

• High-resolution 0.5 meter grid data for precise bathymetric analysis.
• Data provided in three vertical datums (MSL, LAT, Ellipsoid) for flexibility in geospatial applications.
• Acquired using a Kongsberg EM 2040D multibeam echosounder, a standard for hydrographic surveys.
• Survey conducted under the Hydroscheme Industry Partnership Program for the Australian Hydrographic Office.

Limitations

• Dataset is explicitly not to be used for navigational purposes, limiting its operational applications.
• Temporal coverage is limited to a two-day period in September 2020.
• Specific sample data, row counts, and file sizes are unavailable for assessing dataset scale.
