Updated: 2023-11-16
<div>The Cairns Reference Surfaces bathymetry survey was acquired for the Australian Hydrographic Office (AHO) on 27 May 2020. This surface was created from a contracted national reference survey in Cairns 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 R2Sonic 2022, and processed using Caris HIPS & SIPS. Seperate grids in 0.5m resolution are provided for the three 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.</div><div>This dataset is not to be used for navigational purposes.</div>
