EPSG:6939

AGD66 to PNG94 (4)

Attributes

Geodetic CRS: AGD66

Datum: Australian Geodetic Datum 1966

Ellipsoid: Australian National Spheroid

Prime meridian: Greenwich

Data source: EPSG

Information source: Quickclose Geomatics on behalf of Geodetic Section, PNG Office of the Surveyor-General.

Revision date: 2014-11-16

Scope: Medium accuracy applications.

Remarks: Derived in 2014 at 23 stations around the Kutubu oilfields. Aligned to the Bevan Rapids Geodetic Origin AA 070 as required by the Papua New Guinea Oil and Gas Act 1998. Replaces AGD66 to PNG94 (1) (tfm code 5662).

Method: Position Vector transformation (geog2D domain)

Area of use: Papua New Guinea - Papuan fold and thrust belt.
