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。
