Description

The majorAxis parameter represents the semimajor axis. For example, the semimajor axis of the WGS 1984 spheroid is 6378137.0 meters. The flattening value is a small number, such as 0.003352811 (WGS 1984). Often the inverse flattening value is used instead, 298.257223563, and that is what is reported in a well-known text (WKT) version of spheroid. The Define method expects the true flattening value.
