This surface was created from a contracted national reference survey between Goods Island and Goods Island cardinal mark, and Tuesday Island and the Herald Patches QLD, 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 EM2040D, and processed using QPS Qimera. Seperate grids in 0.5m resolution are provided for the two surveyed sites 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": [[[142.0664, -10.66214], [142.3827, -10.66214], [142.3827, -10.45585], [142.0664, -10.45585], [142.0664, -10.66214]]]} 142.0664 142.3827 -10.66214 -10.45585 AusSeabed EARTH SCIENCES Earth Science | Oceans | Bathymetry/Seafloor Topography | Bathymetry HVC_144641 Oceans Published_External bathymetric grids bathymetry marine multibeam AHO Reference Surface (Torres Strait) 2023 0.5m (zip) [128.1 MB] documentDigital AHO Reference Surface (Torres Strait) 2023 0.5m (zip) [128.1 MB] ZIP
