EPSG:10853

ITRF2020 to PNG94 (1)

Attributes

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)

Area of use: Papua New Guinea - onshore and offshore - Western Province, Gulf Province, Central Province, National Capital District and maritime zones offshore of these provinces.
