Geodetic CRS: ITRF2020
Datum: International Terrestrial Reference Frame 2020
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: PNG Office of the Surveyor General.
Revision date: 2025-05-05
Scope: Geodesy.
Remarks: Transformation derived by inversion of seven site velocities within the transformation coverage area. Transformation accuracy at 2σ is 0.15 m between 1994.0 and 2035.0 for locations within Papuan Foreland. Transformation precision degrades in plate margin deforming zone (PFTB) near plate boundary with NGH and Woodlark plates. Transformation not valid outside stated extent.
Method: Time-dependent Coordinate Frame rotation (geocen)
