The Broome Reference Surfaces bathymetry survey was acquired for the Australian Hydrographic Office (AHO) during the period 25 Sep 2020 - 26 Sep 2020. 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.

The Hobart Reference Surfaces bathymetry survey was acquired for the Australian Hydrographic Office (AHO) on 10 Oct to 8 Nov 2021. This surface was created from a contracted national reference survey in Hobart TAS, 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. Separate grids in 0.5m and 1m resolutions are provided for the two surveyed sites within this survey area in MSL, LAT and Ellipsoid vertical datum. The dataset was then exported as 0.5m and 1m resolutions, 32 bit floating point GeoTIFF grid of the survey area. This dataset is not to be used for navigational purposes.
