Method Detail

parseCoordinateSystem

CoordinateSystem parseCoordinateSystem(T crsDefintion)
                                       throws CRSConfigurationException

Parameters:

crsDefintion - to be parsed

Returns:

an instance of the given crs or null if the crsDefinition is null or could not be mapped to a valid type.

Throws:

CRSConfigurationException - if something went wrong while constructing the crs.

getVersion

String getVersion()
                  throws CRSConfigurationException

Returns:

the version of the root element of the empty string if no version attribute was found in the root element.

Throws:

CRSConfigurationException - if the root element is empty

parseTransformation

Transformation parseTransformation(T transformationDefinition)

Retrieves a transformation from the resource.

Parameters:

transformationDefinition -

Returns:

the parsed transformation or null if no transformation could be parsed.

getGeodeticDatumForId

GeodeticDatum getGeodeticDatumForId(String datumID)
                                    throws CRSConfigurationException

Parameters:

datumID -

Returns:

the

Throws:

CRSConfigurationException

getPrimeMeridianForId

PrimeMeridian getPrimeMeridianForId(String meridianID)
                                    throws CRSConfigurationException

Parameters:

meridianID - the id to search for.

Returns:

the primeMeridian with given id or null

Throws:

CRSConfigurationException - if the longitude was not set or the units could not be parsed.

getEllipsoidForId

Ellipsoid getEllipsoidForId(String ellipsoidID)
                            throws CRSConfigurationException

Tries to find a cached ellipsoid, if not found, the config will be checked.

Parameters:

ellipsoidID -

Returns:

an ellipsoid or null if no ellipsoid with given id was found, or the id was null or empty.

Throws:

CRSConfigurationException - if something went wrong.

parseIdentifiableObject

CRSIdentifiable parseIdentifiableObject(String id)

Gets the Element for the given id and heuristically check the localname of the resulting root Element. This version supports following local names (see schema):

• ellipsoid
• geodeticDatum
• projectedCRS
• geographicCRS
• compoundCRS
• geocentricCRS
• primeMeridian
• wgs84Transformation

Parameters:

id - to look for.

Returns:

the instantiated CRSIdentifiable or null if it could not be parsed.

getAvailableCRSCodes

List<CRSCodeType[]> getAvailableCRSCodes()
                                         throws CRSConfigurationException

Returns:

all available codetypes, each sole array should reference the ids of one single crs.

Throws:

CRSConfigurationException

getProjectionForId

Projection getProjectionForId(String projectionId,
                              GeographicCRS underlyingCRS)

Parameters:

projectionId - of the projection

underlyingCRS - of the projection

Returns:

the projection denoted by the given id, or null if no such projection could be loaded.
