public abstract class CentralProjection
extends PropertyBundles
implements Projection

Abstract base class for sphere to planar projections. This class is only used for central projection, i.e. projections with a defined center of projection. The simpliest application is the orthonormal projection. The coordinate system used on the sphere is the longitude/latitude system, commonly used in astronomy and geography. Both coordinates are in degrees.
