Method Summary

Transformation	getTransformation(CoordinateSystem sourceCRS, CoordinateSystem targetCRS) Implementations should find a given transformation (chain) which transforms coordinates of the given coordinate system into coordinates of the target crs.
Helmert	getWGS84Transformation(GeographicCRS sourceCRS) Implementations should find the helmert transformation which transforms coordinates of the geodetic datum into coordinates of the WGS84 datum.

Method Detail

getWGS84Transformation

Helmert getWGS84Transformation(GeographicCRS sourceCRS)

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

Parameters:

sourceCRS - to retrieve the transformation for.

Returns:

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

getTransformation

Transformation getTransformation(CoordinateSystem sourceCRS,
                                 CoordinateSystem targetCRS)

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

Parameters:

sourceCRS - start point of the transformation.

targetCRS - end point of the transformations

Returns:

the Transformation or null if no such transformation was defined.
