This surface was created from a contracted national reference survey between Gantheaume Point and Talboys Rock, Broome WA, collected for the purpose of calibrating multibeam echosounders. It was conducted for the Australian Hydrographic Office as part of the Hydroscheme Industry Partnership Program, acquired using Kongsberg EM 2040D, and processed using Caris HIPS & SIPS. A grid in 0.5m resolution is provided for the surveyed site within this survey area in MSL, LAT and Ellipsoid vertical datum. The dataset was then exported as a 0.5m resolution, 32 bit floating point GeoTIFF grid of the survey area. This dataset is not to be used for navigational purposes. {"type": "Polygon", "coordinates": [[[122.0652, -17.89026], [122.0704, -17.89026], [122.0704, -17.88544], [122.0652, -17.88544], [122.0652, -17.89026]]]} 122.0652 122.0704 -17.89026 -17.88544 AusSeabed EARTH SCIENCES Earth Science | Oceans | Bathymetry/Seafloor Topography | Bathymetry HVC_144641 Oceans Published_External bathymetric grids bathymetry marine multibeam AHO Reference Surface (Broome) 2023 0.5m (zip) [90.2 MB] documentDigital AHO Reference Surface (Broome) 2023 0.5m (zip) [90.2 MB] ZIP
