Description
Summary: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.
