Remarks

This class introduces the following properties.

• Ellipsoid.SemimajorAxis - returns the value of the ellipsoid’s semimajor axis.
• Ellipsoid.SemiminorAxis - returns the value of the ellipsoid’s semiminor axis.
• Ellipsoid.Flattening - returns the flattering value.

To create an ellipsoid use one of the following methods.

• Ellipsoid.CreateByTwoAxes - create an ellipsoid by the semimajor and semiminor axis.
• Ellipsoid.CreateBySemimajorAndInverseFlattering - create an ellipsoid by the semimajor axis and the inverse flattering value.

The objects of this class are used by EllipsoidBasedCartesianToGeoConverter class descendants.
