public class CoordinateReferenceSystem
extends java.lang.Object
Ellipsoid
specifies how the shape of the Earth is approximated
Datum
provides the mapping from the ellipsoid to
actual locations on the earth
Projection
method maps the ellpsoidal surface to a planar space.
(The projection method may be null in the case of geodetic coordinate systems).
Unit
indicates how the ordinate values
of coordinates are interpreted

public CoordinateReferenceSystem createGeographic()
CoordinateReferenceSystem
based on the Datum
of this CRS.
This is useful for defining CoordinateTransform
s
to and from geographic coordinate systems,
where no datum transformation is required.
The Units
of the geographic CRS are set to Units.DEGREES
