Geodetic CRS: AGD66
Datum: Australian Geodetic Datum 1966
Ellipsoid: Australian National Spheroid
Prime meridian: Greenwich
Data source: EPSG
Information source: GDA Technical Manual. http://www.icsm.gov.au/gda
Revision date: 2021-01-18
Scope: Transformation of coordinates at 0.5m level of accuracy.
Remarks: Replaces AGD66 to GDA94 variants 6, 7 and 10 (codes 1506 1507 1596). Input expects longitudes to be positive west; source and target CRSs AGD66 (code 4202) and GDA94 (code 4283) both have longitudes positive east.
Method: NTv2
