Geodetic CRS: ITRF2008
Datum: International Terrestrial Reference Frame 2008
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: National Geodetic Survey (NGS).
Revision date: 2019-09-17
Scope: Geodesy.
Remarks: Scale difference in ppb and scale difference rate in ppb/yr where 1/billion = 1E-9 or nm/m. Joint derivation by Canada and US (tfm 6864) concatenated with IGS value for ITRF96>97 and IERS ITRF97>2008 transformations. See tfm 8264 for Canadian equivalent.
