Australian Hydrographic Service Surveys at Casey Station - ITRF2000

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_appraisedAll 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,    MeaningEasting,    Easting,    Easting ITRF2000Northing,    Northing,    Northing ITRF2000CD_To_GRS8,    CD_To_GRS80,    LAT (Chart Datum) to the EllipsoidCD_TO_MSL_Casey,    CD_To_MSL_Casey,    Ellipsoid to Casey MSLZ_To_GRS80,    Z_To_GRS80,    Height to the EllipsoidZ_To_MSL_Casey,    Z_To_MSL_Casey,    Local MSL orthometric heightVert_Uncer,    Vertical_Uncertainty,    How good is the Vertical PositionHoriz_Unce,    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 Casey Final.xlsx’ for further details.
