public interface Conversion
- extends Operation
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.

- GeoAPI 1.0

- Abstract specification 2.0

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.
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.
getOperationVersion
@UML(identifier="operationVersion",
obligation=CONDITIONAL,
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
