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.Shp All 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, Meaning Easting, Easting, Easting ITRF2000 Northing, Northing, Northing ITRF2000 CD_To_GRS8, CD_To_GRS80, LAT (Chart Datum) to the Ellipsoid LAT_to_GRS80, LAT_to_GRS80, LAT (Chart Datum) to GSR80 LAT_to_MSL_Mawson, LAT_to_MSL_Mawson, LAT to Mawson MSL Z_To_GRS80, Z_To_GRS80, Height to the Ellipsoid Z_To_MSL_Mawson, Z_To_MSL_Mawson, Local MSL orthometric height Vertical_U, Vertical_Uncertainty, How good is the Vertical Position Horizontal, Horizontal Uncertainty, How good is the Horizontal Position Uncertaint, 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 m See the attached document ‘Metadata_Record_Mawson Final REV2.xlsx’ for further details.
