Geodetic Datum used in World

World Geodetic System 1984 is a geodetic datum first defined in and is suitable for use in World.. World Geodetic System 1984 references the WGS 84 ellipsoid and the Greenwich prime meridian. World Geodetic System 1984 origin is Defined through a consistent set of station coordinates. These have changed with time: by 0.7m on 1994-06-29 (G730), a further 0.2m on 1997-01-29 (G873), 0.06m on 2002-01-20 (G1150), 0.2m on 2012-02-08 (G1674) and 0.02m on 2013-10-16 (G1762). World Geodetic System 1984 is a geodetic datum for Satellite navigation. It was defined by information from NIMA TR8350.2 June 2004 revision. http://earth-info.nga.mil/GandG/publications/tr8350.2/tr8350_2.html and http://gis-lab.info/docs/nima-tr8350.2-addendum.pdf. Also NGA.STND.0036_1.0.0_WGS84 of 2014-07-08. EPSG::6326 has been the then current realisation. No distinction is made between the original and subsequent (G730, G873, G1150, G1674 and G1762) WGS 84 frames. Since 1997, WGS 84 has been maintained within 10cm of the then current ITRF.
