Thread safety: This property is thread-safe.
Syntax
public static Ellipsoid Grs1980 { get; }Property Value
Type: Ellipsoid
The predefined ellipsoid GRS 1980.
The predefined ellipsoid GRS 1980.
Remarks
The EPSG code is 7019.
The equatorial radius is 6378137 m; the inverse flattening is 298.257222101.
This ellipsoid was adopted by IUGG 1979 in Canberra (International Union of Geodesy and Geophysics). For practical purposes, it is the same as the Wgs84 ellipsoid. There is a slight difference in the inverse flattening, but it corresponds to a difference of only 0.1 millimeter in the polar radius.
