ITRF2005 to ITRF96 (1)

Attributes

Geodetic CRS: ITRF2005

Datum: International Terrestrial Reference Frame 2005

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Land Information New Zealand (LINZ) technical note 2017-05-09, "Transforming between ITRF and NZGD2000".

Revision date: 2019-05-28

Scope: Geodesy.

Remarks: Scale difference in ppb and scale difference rate in ppb/yr where 1/billion = 1E-9 or nm/m. Used as first step in ITRF2005 to NZGD2000 concatenated operations, followed by application of NZGD2000 deformation model.

Method: Time-dependent Position Vector tfm (geocentric)

Area of use: New Zealand - onshore and offshore. Includes Antipodes Islands, Auckland Islands, Bounty Islands, Chatham Islands, Cambell Island, Kermadec Islands, Raoul Island and Snares Islands.
