This consolidated dataset consisting of Australian Hydrographic Service (AHS) surveys HI468, HI590, HI621 and HI634 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: - HI468_Davis_Z43_Appraised_Part_ITRF2000 - HI468_Davis_Z44_Appraised_ITRF2000 - HI590_Davis_Part_ITRF2000 - HI621B_Davis_Merged_ITRF2000 - HI634_Davis_AreaA_ITRF2000 - HI634_Davis_AreaD_ITRF2000 - HI634_Davis_AreaF_ITRF2000 - HI634_Davis_AreaI_ITRF2000 - HI634_Davis_AreaJ3_ITRF2000 - HI634_Davis_AreaJ4_ITRF2000 - HI634_Davis_Rocks_ITRF2000 All data are in horizontal datum ITRF2000 and have been combined into a single ESRI geodatabase feature class titled AHS_Surveys_Davis_ITRF2000. Attribute data shows quality information, conversion factors (shift in metres) for multiple datums and the MSL orthometric height in the Davis 83 datum: Column Name Alias Meaning Easting, Easting, Easting ITRF2000 Northing, Northing, Northing ITRF2000 CD_To_GRS8, CD_To_GRS80, LAT (Chart Datum) to the Ellipsoid GRS80_To_D, GRS80_To_DAVIS83_MSL, Ellipsoid to DAVIS Height Datum 83 Z_To_GRS80, Z_To_GRS80, Height to the Ellipsoid Z_To_DAVIS, Z_To_DAVIS83_MSL, Local MSL orthometric height (DAVIS Height Datum 83) 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 is 0.24 to 0.5 m for hydrographic values and 0.25 to 0.5 m for terrestrial values. See the attached document ‘Metadata_Record_Davis_Final (002).xlsx’ for further details.
