    dct:description """The Banks Strait Reference Surfaces bathymetry survey was acquired for the Australian Hydrographic Office (AHO) on 17 Dec 2021. This surface was created from a contracted national reference survey within Banks Strait to Cape Barren, TAS, collected for the purpose of calibrating multibeam echosounders.&nbsp;It was conducted for the Australian Hydrographic Office as part of the Hydroscheme Industry Partnership Program, acquired using Kongsberg EM 2040 MkII and Kongsberg EM 2040P, and processed using QPS Qimera. 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.""" ;
