Full description

The AADC (Australian Antarctic Data Centre) is in the process of converting all internally held spatial datasets to the ITRF2000 horizontal datum. This consolidated dataset consists of surveys HI623_alatB_gg, HI625_alatB_GG, HI632_alat_B_gg, HI632_alat_C_gg, LADSII_MMI20756_HSDB_T0001_SD_100029052_op, LADSII_MMI20756_HSDB_T0001_SD_100029053_op, LADSII_MMI20756_HSDB_T0001_SD_100029054_op converted to 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 March 2021.

Included survey datasets:
•    HI623_alatB_gg
•    HI625_alatB_GG
•    HI632_alat_B_gg
•    HI632_alat_C_gg
•    LADSII_MMI20756_HSDB_T0001_SD_100029052_op
•    LADSII_MMI20756_HSDB_T0001_SD_100029053_op
•    LADSII_MMI20756_HSDB_T0001_SD_100029054_op

All data are in horizontal datum ITRF2000 and have been combined into a single ESRI geodatabase feature class titled AHS_Surveys_Macca_ITRF2000.

Attribute data shows quality information, conversion factors (shift in metres) for multiple datums and the MSL orthometric height:

Northing    Northing    Northing ITRF2000
LAT_to_GRS    LAT_to_GRS    LAT (Chart Datum) to GSR80
LAT_to_Mac    LAT_to_Mac    LAT to Macca MSL
Z_To_GRS80    Z_To_GRS80    Height to the Ellipsoid
Z_To_Macca    Z_To_Macca    Local MSL orthometric height
Vertical_U    Vertical_U    How good is the Vertical Position
Horizontal    Horizontal    How good is the Horizontal Position
Uncertaint    Uncertaint    Uncertainty Comments

Vertical uncertainty ranges from 0.5 to 1.2 m and horizontal uncertainty ranges from 2 to 5.5 m. Null values indicate unknown uncertainty.

See the attached document ‘Metadata_Record_Macqaurie Island Final.xlsx’ for further details.

Dataset updated in August, 2023 to add a csv version of the dataset.
