Method Detail

getWGS84Transformation

public Helmert getWGS84Transformation(IGeographicCRS sourceCRS)

Description copied from interface: CRSResource

Implementations should find the helmert transformation which transforms coordinates of the geodetic datum into coordinates of the WGS84 datum. If no such transformation could be found, the implementation should return null

Specified by:

getWGS84Transformation in interface CRSResource<org.apache.axiom.om.OMElement>

Parameters:

sourceCRS - to retrieve the transformation for.

Returns:

the Helmert transformation or null if no such transformation was defined.

getTransformation

public Transformation getTransformation(ICRS sourceCRS,
                                        ICRS targetCRS)

Description copied from interface: CRSResource

Implementations should find a given transformation (chain) which transforms coordinates of the given coordinate system into coordinates of the target crs. If no such transformation could be found, the implementation should return null

Specified by:

getTransformation in interface CRSResource<org.apache.axiom.om.OMElement>

Parameters:

sourceCRS - start point of the transformation.

targetCRS - end point of the transformations

Returns:

the Transformation or null if no such transformation was defined.

getURIAsType

public org.apache.axiom.om.OMElement getURIAsType(String uri)
                                           throws IOException

Description copied from interface: XLinkResolver

Opens a stream to a resource which is defined by the uri.

Specified by:

getURIAsType in interface XLinkResolver<org.apache.axiom.om.OMElement>

Parameters:

uri - to locate

Returns:

an opened InputStream to the given resource or null if no resource was found.

Throws:

IOException - If an error occurred while locating or opening the resource.

getAvailableCRSIds

public List<CRSCodeType[]> getAvailableCRSIds()

Specified by:

getAvailableCRSIds in interface GMLResource

Returns:

the available crs ids of this gml resource.

getAvailableCRSs

public List<ICRS> getAvailableCRSs()

Specified by:

getAvailableCRSs in interface GMLResource

Returns:

the list of coordinate systems.
