The coordinate origin of WGS 84 is meant to be located at the Earth's center of mass; the error is believed to be less than 2 cm. In WGS 84, the meridian of zero longitude is the IERS Reference Meridian. It lies 5.31 arc seconds east of the Greenwich Prime Meridian, which corresponds to 102.5 metres (336.3 feet) at the latitude of the R…

Oct 06, 2015 · The Global Positioning System uses the World Geodetic System (WGS84) as its reference coordinate system. It’s made up of a reference ellipsoid, a standard coordinate system, altitude data, and a geoid. Similar to the North American Datum of 1983 (NAD83), it uses the Earth’s center mass as the coordinate origin. Reviews: 9

WGS84 can also be one type of geographic coordinate system. The WGS84 Coordinate Systems adds Greenwich as the starting point (prime meridian) for the longitude (0°) and sets the units in degrees (°). This coordinate systems also has a unique reference code, the so-called EPSG codewhich is 4326. The illustration below lists the WGS84 system with al...

The North American 1983 datum (NAD83) uses the Geodetic Reference System (GRS80) ellipsoid while the World Geodetic System of 1984 (WGS84) uses the WGS 84 ellipsoid. The dimensions of these ellipsoids differ slightly. For more information, refer to Projection basics the GIS professional needs to know. A map will have only one coordinate system ...
