CoordinateTransformer

public CoordinateTransformer(CoordinateSystem targetCRS)
                      throws IllegalArgumentException

Creates a new CoordinateTransformer object.

Parameters:

targetCRS -

Throws:

IllegalArgumentException - if the given parameter is null.

CoordinateTransformer

public CoordinateTransformer(String targetCRS)
                      throws UnknownCRSException,
                             IllegalArgumentException

Creates a new CoordinateTransformer object, with the given id as the target CRS.

Parameters:

targetCRS - an identifier to which all other CRS's shall be transformed.

Throws:

UnknownCRSException - if the given crs name could not be mapped to a valid (configured) crs.

IllegalArgumentException - if the given parameter is null.

CoordinateTransformer

public CoordinateTransformer(Transformation transformation)
                      throws IllegalArgumentException

Creates a new CoordinateTransformer object, with the given id as the target CRS.

Parameters:

transformation - to be used.

Throws:

IllegalArgumentException - if the given parameter is null.

Method Detail

transform

public List<javax.vecmath.Point3d> transform(CoordinateSystem sourceCRS,
                                             List<javax.vecmath.Point3d> points)
                                      throws TransformationException,
                                             IllegalArgumentException

Transforms all points to the CoordinateTransformer's coordinate system.

Parameters:

sourceCRS - in which the given points are referenced.

points - to transform.

Returns:

a list of transformed point3d's or an empty list if something went wrong, never null

Throws:

TransformationException - if no transformation could be created for the given source and target crs.

IllegalArgumentException - if the sourceCRS is null

transform

public double[] transform(CoordinateSystem sourceCRS,
                          double[] input,
                          double[] out)
                   throws IllegalArgumentException,
                          TransformationException

Transforms a given coordinate into the CoordinateTransformer's coordinate system.

Parameters:

sourceCRS - crs of the input coordinate, must not be null

input - input coordinate, must not be null and array length must match the number of dimensions of sourceCRS

out - output coordinate, used to store the transformed ordinates, must not be null and array length must match the number of dimensions of the target crs

Returns:

transformed coordinate, this is the same instance as out

Throws:

TransformationException

IllegalArgumentException
