org.opengis.referencing.operation.CoordinateOperationFactory.createOperation()
Returns an operation for conversion or transformation between two coordinate reference systems.
- If an operation exists, it is returned.
- If more than one operation exists, the default is returned.
- If no operation exists, then the exception is thrown.
Implementations may try to {@linkplain CoordinateOperationAuthorityFactory#createFromCoordinateReferenceSystemCodes query an authority factory} first, and compute the operation next if no operation from{@code source} to {@code target} code was explicitly defined by the authority. @param sourceCRS Input coordinate reference system. @param targetCRS Output coordinate reference system. @return A coordinate operation from {@code sourceCRS} to {@code targetCRS}. @throws OperationNotFoundException if no operation path was found from {@code sourceCRS}to {@code targetCRS}. @throws FactoryException if the operation creation failed for some other reason.
