资源简介:
This consolidated dataset consists of Australian Hydrographic Service (AHS) surveys HI621C, 5135 (Terrestrial), HI364, HI514, and HI607 converted to International Terrestrial Reference Frame 2000 (ITRF2000) horizontal datum with Z conversion values for multiple height datums. The data was provided to the AAD by Paul Digney of Jacobs consulting in February 2021.Included survey datasets:•    HI621C_MAWSON_merged.shp•    HI621C_MAWSON_merged.shp•    Terrestrial_Data_5135•    HI364_HSDB_T0001_SD_100035029_op_soundings•    QC_HI 514 HDCS_FDD_appraised (Mawson Approches)•    HI607.ShpAll data are in horizontal datum ITRF2000 and have been combined into a single ESRI geodatabase feature class titled AHS_Surveys_Mawson_ITRF2000.Attribute data shows quality information, conversion factors (shift in metres) for multiple datums and the MSL orthometric height:Column Name,     Alias,    MeaningEasting,    Easting,    Easting ITRF2000Northing,    Northing,    Northing ITRF2000CD_To_GRS8,    CD_To_GRS80,     LAT (Chart Datum) to the EllipsoidLAT_to_GRS80,    LAT_to_GRS80,    LAT (Chart Datum) to GSR80LAT_to_MSL_Mawson,    LAT_to_MSL_Mawson,    LAT to Mawson MSLZ_To_GRS80,    Z_To_GRS80,    Height to the EllipsoidZ_To_MSL_Mawson,    Z_To_MSL_Mawson,    Local MSL orthometric heightVertical_U,    Vertical_Uncertainty,    How good is the Vertical PositionHorizontal,    Horizontal Uncertainty,    How good is the Horizontal PositionUncertaint,    Uncertainty Comments,    Depth_Comm,     Depth_Comments,            Vertical uncertainty ranges from 0.05 to 0.64 m and horizontal uncertainty ranges from 0.05 to 1.0 mSee the attached document ‘Metadata_Record_Mawson Final REV2.xlsx’ for further details.The dataset was updated in August, 2023 to add a csv version of the data.

本整合数据集包含澳大利亚水文局(Australian Hydrographic Service,AHS)的多份测量成果:HI621C、5135(陆地版)、HI364、HI514及HI607,已转换至国际陆地参考框架2000(International Terrestrial Reference Frame 2000,ITRF2000)水平基准面,并附带多类高程基准面的Z转换参数。该数据由Jacobs咨询的Paul Digney于2021年2月交付予澳大利亚南极署(Australian Antarctic Division,AAD)。 包含的测量数据集如下: • HI621C_MAWSON_merged.shp • HI621C_MAWSON_merged.shp • Terrestrial_Data_5135 • HI364_HSDB_T0001_SD_100035029_op_soundings • QC_HI 514 HDCS_FDD_appraised(莫森海域水道) • HI607.Shp 所有数据均采用ITRF2000水平基准面,并已整合至名为AHS_Surveys_Mawson_ITRF2000的单一ESRI地理数据库要素类中。 属性数据包含质量信息、多基准面转换因子(单位:米)以及平均海平面(Mean Sea Level,MSL)正高信息,各字段说明如下: 1. 字段名:Easting,别名:Easting,含义:ITRF2000东向坐标 2. 字段名:Northing,别名:Northing,含义:ITRF2000北向坐标 3. 字段名:CD_To_GRS8,别名:CD_To_GRS80,含义:海图基准面坐标至椭球面的转换值 4. 字段名:LAT_to_GRS80,别名:LAT_to_GRS80,含义:海图基准面坐标至GRS80椭球的转换值(原文笔误GSR80已修正) 5. 字段名:LAT_to_MSL_Mawson,别名:LAT_to_MSL_Mawson,含义:海图基准面坐标至莫森站平均海平面的转换值 6. 字段名:Z_To_GRS80,别名:Z_To_GRS80,含义:高程至椭球面的转换值 7. 字段名:Z_To_MSL_Mawson,别名:Z_To_MSL_Mawson,含义:本地平均海平面正高 8. 字段名:Vertical_U,别名:Vertical_Uncertainty,含义:垂直位置精度水平 9. 字段名:Horizontal,别名:Horizontal Uncertainty,含义:水平位置精度水平 10. 字段名:Uncertaint(应为Uncertainty),别名:Uncertainty Comments,含义:不确定性注释 11. 字段名:Depth_Comm,别名:Depth_Comments,含义:深度注释 垂直精度范围为0.05至0.64米,水平精度范围为0.05至1.0米。详细信息请参阅附件《Metadata_Record_Mawson Final REV2.xlsx》。 本数据集于2023年8月更新,新增了数据的CSV格式版本。
