The Darwin Reference Surfaces bathymetry survey was acquired for the Australian Hydrographic Office (AHO) on 8 Jul 2020. This surface was created from a contracted national reference survey in Darwin NT, 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 2026 and R2Sonic 2024, and processed using QPS Qimera. Separate 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.
