Brief description

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.
