WebBrief Description: WGS 84 is an Earth-centered, Earth-fixed terrestrial reference system and geodetic datum. WGS 84 is based on a consistent set of constants and model parameters that describe the Earth's size, shape, and gravity and geomagnetic fields. WebBut Yellows use an earth radius = 6378 137m, which is the WGS-84 ellipsoid, semi-major axis, while Sulkeh use 6371 000 m. Using a radius = 6378 137 m in the Sulkeh' method, gives 269533625893 square meters.
