Metadata details

AHS_Surveys_Casey_ITRF2000

All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

    Description

    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:
