Constructor Detail

GeodeticCRS

protected GeodeticCRS(Identifier identifier,
                      GeodeticDatum datum,
                      CoordinateSystem coordinateSystem)

Creates a new GeodeticCRS.

Parameters:

identifier - the identifier of the GeodeticCRS

datum - the datum associated with the GeodeticCRS

coordinateSystem - the coordinate system associated with the GeodeticCRS

Method Detail

getProjection

public Projection getProjection()

Description copied from interface: CoordinateReferenceSystem

Returns the Projection to which this CoordinateReferenceSystem is refering. It returns null if no projection is defined for this CRS.

Specified by:

getProjection in interface CoordinateReferenceSystem

Returns:

See Also:

CoordinateReferenceSystem.getProjection()

getType

public abstract CoordinateReferenceSystem.Type getType()

Description copied from interface: CoordinateReferenceSystem

Returns this CoordinateReferenceSystem Type.

Specified by:

getType in interface CoordinateReferenceSystem

Returns:

See Also:

CoordinateReferenceSystem.getType()

getCoordinateSystem

public CoordinateSystem getCoordinateSystem()

Description copied from interface: CoordinateReferenceSystem

Returns the CoordinateSystem used by this CoordinateReferenceSystem.

Specified by:

getCoordinateSystem in interface CoordinateReferenceSystem

Returns:

See Also:

CoordinateReferenceSystem.getCoordinateSystem()

getDatum

public GeodeticDatum getDatum()

Returns the Datum to which this CoordinateReferenceSystem is refering.

Specified by:

getDatum in interface CoordinateReferenceSystem

Returns:

toGeographicCoordinateConverter

public abstract CoordinateOperation toGeographicCoordinateConverter()
                                                             throws CoordinateOperationException

Creates a CoordinateOperation object to convert coordinates from this CoordinateReferenceSystem to a Geographic3DCRS based on the same GeodeticDatum, and using normal SI units in the following order : latitude (rad), longitude (rad) height (m).

Returns:

Throws:

CoordinateOperationException

fromGeographicCoordinateConverter

public abstract CoordinateOperation fromGeographicCoordinateConverter()
                                                               throws CoordinateOperationException

Returns:

Throws:

CoordinateOperationException

toWKT

public abstract String toWKT()

Returns a WKT representation of the geodetic CRS.

Specified by:

toWKT in interface CoordinateReferenceSystem

Returns:

toString

public String toString()
