Geodetic CRS: GDA94
Datum: Geocentric Datum of Australia 1994
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: ANZLIC Intergovernmental Committee on Surveying and Mapping (ICSM) (http://www.icsm.gov.au).
Revision date: 2021-01-18
Scope: Alignment of datasets referenced to WGS 84 which have been derived from GDA2020 via the null transformation EPSG::8450 with GDA94 datasets.
Remarks: Concatenation of CTs 8048 and 8450 through GDA2020. Scale difference in ppb where 1/billion = 1E-9. See GDA94 to WGS 84 (2) (CT code 9689) for alternative for Australia including distortion model.
Method: Coordinate Frame rotation (geog2D domain)
