Geodetic CRS: ITRF2008
Datum: International Terrestrial Reference Frame 2008
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 ITRF2008 to NZGD2000 concatenated operations, followed by application of NZGD2000 deformation model.
Method: Time-dependent Position Vector tfm (geocentric)
