Constructor Detail

ReferenceEllipsoid

public ReferenceEllipsoid(java.lang.String inName,
                          double inSemiMajorAxis,
                          double inSemiMinorAxis)

Create a new reference ellipsoid from the semi-major (equatorial radius) and semi-minor axes. The semi-minor axis of the ellipsoid can be calculated from the eccentricity squared (e²) and the semi-major axis (a²) by finding sqrt(-e²a² + a²)

Parameters:

inName - the name of the reference ellipsoid

inSemiMajorAxis -

inSemiMinorAxis -
