ConvenienceTransformFactory() Creates a new ConvenienceTransformFactory object.

Method Summary

private MathTransform	getGeogrToProjected(CoordinateSystem src, CoordinateSystem dest) retuns a MathTransform object for the transformation of coodinates from a geographic to a projected coodinate systems
static ConvenienceTransformFactory	getInstance()
private MathTransform	getProjectedToGeogr(CoordinateSystem src, CoordinateSystem dest) retuns a MathTransform object for the transformation of coodinates from a projected to a geographic coodinate systems
private MathTransform	getProjectedToProjected(CoordinateSystem src, CoordinateSystem dest) retuns a MathTransform object for the transformation of coodinates between two projected coodinate systems
MathTransform	getTransform(CoordinateSystem src, CoordinateSystem dest) returns a Transform object that's able to perform a coordinate tranformation from the source- to the destination-coordinate system.
MathTransform	getTransform(java.lang.String src, java.lang.String dest) returns a Transform object that's able to perform a coordinate tranformation from the source- to the destination-coordinate system.

Creates a new ConvenienceTransformFactory object.

Method Detail

getInstance

public static ConvenienceTransformFactory getInstance()

Returns:

getTransform

public MathTransform getTransform(java.lang.String src,
                                  java.lang.String dest)
                           throws java.lang.Exception

returns a Transform object that's able to perform a coordinate tranformation from the source- to the destination-coordinate system. At the moment only transformations between geographic coordinate systems geographic and projected coordinated systems and vice versa are supported.

Parameters:

src - source coordinated system

dest - destination (target) coodinate system

Returns:

an instance of net.ct.Transform

Throws:

java.lang.Exception - will be thrown if the desired transformaion isn't possible

getTransform

public MathTransform getTransform(CoordinateSystem src,
                                  CoordinateSystem dest)
                           throws java.lang.Exception

returns a Transform object that's able to perform a coordinate tranformation from the source- to the destination-coordinate system. At the moment only transformations between geographic coordinate systems geographic and projected coordinated systems and vice versa are supported.

Parameters:

src - source coordinated system

dest - destination (target) coodinate system

Returns:

an instance of net.ct.Transform

Throws:

java.lang.Exception - will be thrown if the desired transformaion isn't possible

private MathTransform getGeogrToProjected(CoordinateSystem src,
                                          CoordinateSystem dest)
                                   throws java.lang.Exception

retuns a MathTransform object for the transformation of coodinates from a geographic to a projected coodinate systems

Throws:

java.lang.Exception

getProjectedToProjected

private MathTransform getProjectedToProjected(CoordinateSystem src,
                                              CoordinateSystem dest)
                                       throws java.lang.Exception

retuns a MathTransform object for the transformation of coodinates between two projected coodinate systems

Throws:

java.lang.Exception

getProjectedToGeogr

private MathTransform getProjectedToGeogr(CoordinateSystem src,
                                          CoordinateSystem dest)
                                   throws java.lang.Exception

retuns a MathTransform object for the transformation of coodinates from a projected to a geographic coodinate systems

Throws:

java.lang.Exception
