4.1.32 semi-major axis a semi-diameter of the longest axis of an ellipsoid (4.1 .1 2) Note 1 to entry: This equates to the semi-diameter of the ellipsoid measured in its equatorial plane. [SOURCE: ISO 1 91 1 1 :2007, 4.40] 4.1.33 semi-minor axis b semi-diameter of the shortest axis of an ellipsoid (4.1 .1 2) Note 1 to entry: The shortest axis coincides with the rotation axis of the ellipsoid and therefore contains both poles.
