Vertical uncertainty ranges from 0.05 to 0.64 m and horizontal uncertainty ranges from 0.05 to 1.0 m This consolidated dataset consists of Australian Hydrographic Service (AHS) surveys HI621A and HI545 converted to International Terrestrial Reference Frame 2000 (ITRF2000) horizontal datum with Z conversion values for multiple height datums. The data was provided to the Australian Antarctic Division by Paul Digney of Jacobs consulting in February 2021. Included survey datasets: - HI621A.shp (Validated folder) - 1812_5093-HI621A_CASEY_Terrestrial.shp - QC_HI545_12pt5_appraised All data are in horizontal datum ITRF2000 and have been combined into a single ESRI geodatabase feature class titled AHS_Surveys_Casey_ITRF2000. Attribute data shows quality information, conversion factors (shift in metres) for multiple datums and the MSL orthometric height for Casey: Column Name, Alias, Meaning Easting, Easting, Easting ITRF2000 Northing, Northing, Northing ITRF2000 CD_To_GRS8, CD_To_GRS80, LAT (Chart Datum) to the Ellipsoid CD_TO_MSL_Casey, CD_To_MSL_Casey, Ellipsoid to Casey MSL Z_To_GRS80, Z_To_GRS80, Height to the Ellipsoid Z_To_MSL_Casey, Z_To_MSL_Casey, Local MSL orthometric height Vert_Uncer, Vertical_Uncertainty, How good is the Vertical Position Horiz_Unce, 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 Casey Final.xlsx’ for further details. The AADC (Australian Antarctic Data Centre) is in the process of converting all internally held spatial datasets to the ITRF2000 horizontal datum.
