Description: Coordinate system introduced 1.1 WGS-84 coordinate system WGS-84 coordinate system is used by GPS coordinate system is established by the U.S. Defense Mapping Agency in 1987, was replaced by the coordinate system used by GPS (WGS-72 coordinates system) and a GPS coordinate system currently in use. WGS-84 coordinate system origin is at the center of mass of the Earth, Z-axis earth pointing BIHl984.0 very definition of the direction of the agreement, X-axis starting point BIHl984.0 the intersection of the meridian and the equatorial plane, Y axis and X axis and Z axis constitute a right-handed system. Department of WGS-84 ellipsoid parameters are used: a = 6378138m f = 1/298.257223563.
