public class GTTransformUtils
extends java.lang.Object

Utility class to create a GeoTools2 transformation class for a given geoSystem field definition.

This class runs as a singleton to allow for caching of internal fetched transformation routines.

Method Detail

getInstance

public static GTTransformUtils getInstance()
                                    throws org.opengis.referencing.FactoryException

Fetch the singleton instance of the factory. If needed, a new instance will be created.

Returns:

The shared singleton instance of this class

Throws:

org.opengis.referencing.FactoryException - There was a problem creating the class

createSystemTransform

public org.opengis.referencing.operation.MathTransform createSystemTransform(java.lang.String[] systemDef,
                                                                             boolean[] coordSwap)
                                                                      throws org.opengis.referencing.FactoryException

From the given system definition strings, generate a coordinate transformation service.

Check whether we need to reverse the two primary coordinate systems. If true, then the user needs to swap the coordinate values for X and Y.

Parameters:

systemDef - The X3D system definition string

coordSwap - an array of length 1 for returning the primary coordinate swap flag

Returns:

A transform for taking geo coordinates to cartesian

Throws:

org.opengis.referencing.FactoryException
