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.
