Geodetic CRS: AGD84
Datum: Australian Geodetic Datum 1984
Ellipsoid: Australian National Spheroid
Prime meridian: Greenwich
Data source: OGP
Information source: GDA Technical Manual. http://www.icsm.gov.au/gda
Revision date: 2019-09-17
Scope: 0.1m accuracy.
Remarks: Replaces AGD84 to GDA94 (4) (code 1593) which itself replaced variant 3 (code 1559). Input expects longitudes to be + west; EPSG GeogCRS AGD84 (code 4203) and GDA94 (code 4283) both have longitudes positive east. May be used as tfm to WGS 84 - see 15785
Method: NTv2
Area of use: Australia - Queensland, South Australia, Western Australia, federal areas offshore west of 129°E.
