Ellipticity. Given a spheroid with equatorial radius and polar radius , the ellipticity is defined by. (1) It is defined analogously to eccentricity and is commonly denoted using the symbols (Snyder 1987, p. 13) or (Beyer 1987). It is related to the flattening by.Flattening - Wikipedia

A sphere of radius a compressed to an oblate ellipsoid of revolution. Flattening is a measure of the compression of a circle or sphere along a diameter to form an ellipse or an ellipsoid of revolution (spheroid) respectively. Other terms used are ellipticity, or oblateness.
