All Implemented Interfaces:

@Deprecated
public class GCTPProjection
extends MapProjection
implements Cloneable

Deprecated.

The native methods of GCTP are no longer supported. Use the MapProjectionFactory to create and work with map projections rather than this class.

The GCTPProjection class implements Earth transform calculations for many common 2D map projections using the native GCTP transformation library. See the General Cartographic Transformations Package (GCTP) class for details on the projections constants and parameters.

3.1.0

Constructor Details

GCTPProjection

public GCTPProjection(int system,
 int zone,
 double[] parameters,
 int spheroid,
 int[] dimensions,
 AffineTransform affine)
               throws NoninvertibleTransformException

Deprecated.

Constructs a map projection from the specified projection and affine transform. The SpheroidConstants and ProjectionConstants class should be consulted for valid parameter constants.

Parameters:

system - the map projection system.

zone - the map projection zone for State Plane and UTM projections.

parameters - an array of 15 GCTP projection parameters.

spheroid - the spheroid code.

dimensions - the dimensions of the data grid as [rows, columns].

affine - the affine transform for translating data [row, column] to map [x, y].

Throws:

NoninvertibleTransformException - if the map projection to data coordinate affine transform is not invertible.
