Interface CoordinateOperationAuthorityFactory

All Superinterfaces:

AuthorityFactory, Factory

@UML(identifier="CT_CoordinateTransformationAuthorityFactory",
     specification=OGC_01009)
public interface CoordinateOperationAuthorityFactory
extends AuthorityFactory

Creates coordinate transformation objects from codes. The codes are maintained by an external authority. A commonly used authority is EPSG, which is also used in the GeoTIFF standard.

Since:

1.0

Method Detail

createOperationMethod

OperationMethod createOperationMethod(String code)
                                      throws NoSuchAuthorityCodeException,
                                             FactoryException

Creates an operation method from a single code. The "authority" and "code" values of the created object will be set to the authority of this object, and the code specified by the client, respectively. The other metadata values may or may not be set.

Parameters:

code - Coded value for operation method.

Returns:

The operation method for the given code.

Throws:

NoSuchAuthorityCodeException - if the specified code was not found.

FactoryException - if the object creation failed for some other reason.

Since:

2.3

Departure from OGC/ISO specification:
This method has been added because OGC 01-009 does not define a factory method for creating such object.

createCoordinateOperation

@UML(identifier="createFromTransformationCode",
     specification=OGC_01009)
CoordinateOperation createCoordinateOperation(String code)
                                              throws NoSuchAuthorityCodeException,
                                                     FactoryException

Creates an operation from a single operation code. The "authority" and "code" values of the created object will be set to the authority of this object, and the code specified by the client, respectively. The other metadata values may or may not be set.

Parameters:

code - Coded value for coordinate operation.

Returns:

The operation for the given code.

Throws:

NoSuchAuthorityCodeException - if the specified code was not found.

FactoryException - if the object creation failed for some other reason.

createFromCoordinateReferenceSystemCodes

@UML(identifier="createFromCoordinateSystemCodes",
     specification=OGC_01009)
Set<CoordinateOperation> createFromCoordinateReferenceSystemCodes(String sourceCRS,
                                                                                                    String targetCRS)
                                                                  throws NoSuchAuthorityCodeException,
                                                                         FactoryException

Creates operations from coordinate reference system codes. This method returns only the operations declared by the authority, with preferred operations first. This method doesn't need to compute operations from source to target CRS if no such operations were explicitly defined in the authority database. Computation of arbitrary operations can be performed by CoordinateOperationFactory.createOperation(sourceCRS, targetCRS) instead.

Parameters:

sourceCRS - Coded value of source coordinate reference system.

targetCRS - Coded value of target coordinate reference system.

Returns:

The operations from sourceCRS to targetCRS.

Throws:

NoSuchAuthorityCodeException - if a specified code was not found.

FactoryException - if the object creation failed for some other reason.
