@UML(identifier="CC_Conversion",
     specification=ISO_19111)
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.

Method Details

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 through General­Derived­CRS.get­Base­CRS() instead.

Specified by:

get­Source­CRS in interface Coordinate­Operation

Returns:

The source CRS, or null if not available.

See Also:

• get­Source­CRS()
• Transformation.get­Source­CRS()

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 through General­Derived­CRS instead.

Specified by:

get­Target­CRS in interface Coordinate­Operation

Returns:

The target CRS, or null if not available.

See Also:

• get­Target­CRS()
• Transformation.get­Target­CRS()

getOperationVersion

@UML(identifier="operationVersion",
     obligation=FORBIDDEN,
     specification=ISO_19111)
String getOperationVersion()

This attribute is declared in Coordinate­Operation but is not used in a conversion.

Specified by:

get­Operation­Version in interface Coordinate­Operation

Returns:

Always null.
