Examples of org.geotools.referencing.crs.DefaultDerivedCRS

org.geotools.referencing.crs.DefaultDerivedCRS
A coordinate reference system that is defined by its coordinate conversion from another coordinate reference system but is not a projected coordinate reference system. This category includes coordinate reference systems derived from a projected coordinate reference system. @since 2.1 @source $URL$ @version $Id$ @author Martin Desruisseaux (IRD)
