Brief description
The Western Approaches to Torres Strait Bathymetry survey was acquired for the Australian Hydrographic Office (AHO) onboard the MV Pacific Conquest, an unmanned vehicle USV and VH-VEH Cessna 441 aircraft during the period 29 October 2020 – 21 February 2021.
This is a contracted survey conducted for the Australian Hydrographic Office by Fugro Australia Marine as part of the Hydroscheme Industry Partnership Program (HIPP).
The survey area is east of the Western approaches to the Torres Strait.
Bathymetry data was acquired using a Kongsberg EM2040 (Dual/Single Head and Dual swath), EM2040P and LADS HD+ and RIEGL VQ-820-G systems and processed using CARIS HIPS & SIPS 11.3.17, LADS HD+ GS, RiWorld processing software.
The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area.
This dataset is not to be used for navigational purposes.

Processing methodology:
This dataset was produced using CARIS HIPS & SIPS as follow:
1. Processed in accordance with HIPP SOR 2020v 1.2 using CUBE techniques, 1m and 2m CUBE surfaces generated as the final L3 product (a gridded surface derived from cleaned point data).
2. Data was provided to Geoscience Australia for publication.
3. The final processed grid was exported as a 32-bit floating point Geotiff at 30 m resolution, referenced to MSL, WGS 84 (EPSG:4326).
DATA QUALITY
This dataset has been subject to independent post-production validation and testing. Tests have been performed for data completeness, correct spatial representation, attribute accuracy, logical consistency, metadata completeness and correctness, and where appropriate for compliance with Geoscience Australia's data dictionaries.
