public interface Conversion
extends SingleOperation
An operation on coordinates that does not include any change of Datum. The best-known
example of a coordinate conversion is a map projection. The parameters describing
coordinate conversions are defined rather than empirically derived.
Note that some conversions have no parameters.

getSourceCRS
@UML(identifier="sourceCRS", obligation=OPTIONAL, specification=ISO_19111) CoordinateReferenceSystem getSourceCRS()Returns the source CRS. Conversions may have a source CRS that is not specified here, but throughGeneralDerivedCRS.getBaseCRS()
instead.- Specified by:
getSourceCRS
in interfaceCoordinateOperation
- Returns:
- The source CRS, or
null
if not available. - See Also:
-
getTargetCRS
@UML(identifier="targetCRS", obligation=OPTIONAL, specification=ISO_19111) CoordinateReferenceSystem getTargetCRS()Returns the target CRS. Conversions may have a target CRS that is not specified here, but throughGeneralDerivedCRS
instead.- Specified by:
getTargetCRS
in interfaceCoordinateOperation
- Returns:
- The target CRS, or
null
if not available. - See Also:
-
getOperationVersion
@UML(identifier="operationVersion", obligation=FORBIDDEN, specification=ISO_19111) String getOperationVersion()This attribute is declared inCoordinateOperation
but is not used in a conversion.- Specified by:
