Brief description
The Furneaux Group, Bass Strait bathymetry survey was acquired for the Australian Hydrographic Office (AHO) using Cessna 441 during the period 11 Apr 2022 – 20 Nov 2022. This was a contracted survey conducted for the Australian Hydrographic Office by Fugro Australia as part of the Hydroscheme Industry Partnership Program. The survey area encompases an area in Furneaux Group, Bass Strait. Bathymetry data was acquired using a LADS HD+ / LADS HD / RIEGL VQ-820-G, and processed using RIEGL RiProcess and CARIS HIPS and SIPS 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.
