AHO Reference Surfaces Hobart 0.5m and 1m 2023 (20230017R)

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.

霍巴特参考地表水深勘测于2021年10月10日至11月8日由澳大利亚水文局（Australian Hydrographic Office, AHO）承接开展。本次地表数据源自塔斯马尼亚州霍巴特市的签约国家基准勘测，其采集目的为校准多波束测深仪。本勘测作为水文计划行业伙伴关系项目（Hydroscheme Industry Partnership Program）的一部分由澳大利亚水文局牵头实施，数据采集使用康士伯Kongsberg EM2040D设备，后经QPS Qimera软件处理完成。本次勘测区域内的两个勘测点位分别提供0.5米与1米分辨率的网格数据，采用平均海平面（MSL, Mean Sea Level）、最低天文潮面（LAT, Lowest Astronomical Tide）及椭球垂直基准面（Ellipsoid vertical datum）三种垂直基准。最终该数据集以0.5米、1米分辨率的32位浮点型GeoTIFF网格格式导出，覆盖整个勘测区域。本数据集不得用于导航用途。
