The Rottnest Reference Surface was created from a bathymetry survey acquired for the Australian Hydrographic Office (AHO) on 11 December 2022. This surface was created from a contracted national reference survey adjacent to Rottnest Island, 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, using a Kongsberg EM2040P and processed using Caris HIPS & SIPS. Separate grids in 0.5m and 2m resolution are provided for the two surveyed sites within this survey area in MSL, LAT and Ellipsoid vertical datums. The datasets were exported as 0.5m and 2m resolution, 32-bit floating point GeoTIFF grids.

This dataset is not to be used for navigational purposes.
