AHO Reference Surfaces Banks Strait 0.5m 2023 (20230009R)

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. 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.

本数据集为班克斯海峡基准面水深测量（Banks Strait Reference Surfaces bathymetry survey），于2021年12月17日为澳大利亚水文局（Australian Hydrographic Office, AHO）完成。该基准面源自塔斯马尼亚州（Tasmania, TAS）巴伦角至班克斯海峡区域的承包国家基准测量工作，采集目的为校准多波束测深仪。本次测量作为澳大利亚水文局水文方案行业伙伴计划（Hydroscheme Industry Partnership Program）的组成部分开展，数据采集使用康斯伯格（Kongsberg）EM 2040 MkII与EM 2040P设备，后处理工作通过QPS Qimera软件完成。针对本次测量范围内的测区，本数据集提供了基于平均海平面（Mean Sea Level, MSL）、天文最低潮面（Lowest Astronomical Tide, LAT）及椭球垂直基准面的0.5米分辨率格网数据。后续该数据集被导出为测量区域的0.5米分辨率32位浮点型GeoTIFF格网文件。本数据集不得用于导航用途。
