Constructor Detail

CoordinateTransformer

public CoordinateTransformer(org.opengis.referencing.crs.CoordinateReferenceSystem crs)
                      throws org.opengis.referencing.FactoryException

Create transformer from CRS

Parameters:

crs - the CRS

Throws:

org.opengis.referencing.FactoryException - if no transformation for the CRS could be found

Method Detail

transform

public double[] transform(double[] from,
                          int dimension)
                   throws org.opengis.referencing.operation.TransformException

Transform an array of coordinates to DefaultGeographicCRS.WGS84

Parameters:

from - the source array of coordinates

dimension - the dimension of the source coordinates. Allowed values are <= 0, 2 and 3. If the value is <= 0 the dimension will be guessed (see guessDimension(double[])).

Returns:

a new array with the destination coordinates of null if the dimension in unknown or the source coordinates could not be transformed

Throws:

org.opengis.referencing.operation.TransformException - if the coordinates could not be transformed

decode

public static org.opengis.referencing.crs.CoordinateReferenceSystem decode(java.lang.String s)
                                                                    throws org.opengis.referencing.FactoryException

Decode CRS from a string. This might be:

• a simple CRS (see CRS.decode(String))
• a compound CRS (see CompoundCRSDecoder.decode(String))
• a WKT string (see WKTCRSDecoder.decode(String))

Parameters:

s - the string

Returns:

the parsed CRS

Throws:

org.opengis.referencing.FactoryException - if the CRS could not be parsed
