Method Detail

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 and projected coordinated systems and vice versa are supported.

Parameters:

src - source coordinated system as a String

dest - destination (target) coodinate system as a String

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

                                   throws java.lang.Exception

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

Throws:
