public class LambertConformal

extends ConicProjection

Lambert Conical Conformal Projection. Areas and shapes are deformed as one moves away from standard parallels. The angles are true in a limited area. This projection is used for the charts of North America. It uses a default central latitude of 40?N.

This implementation provides transforms for three cases of the lambert conic conformal projection:

• Lambert_Conformal_Conic_1SP (EPSG code 9801)
• Lambert_Conformal_Conic_2SP (EPSG code 9802)
• Lambert_Conic_Conformal_2SP_Belgium (EPSG code 9803)

For the 1SP case the latitude of origin is used as the standard parallel (SP). To use a 1SP with a latitude of origin different from the SP, use the 2SP and set both the SP1 and SP2 to the single SP.

protected LambertConformal(Projection parameters)
                    throws MissingParameterException

Deprecated.

Construct a new projection from the supplied parameters.

Parameters:

parameters - The parameter values in standard units.

Method Detail

getName

public java.lang.String getName(java.util.Locale locale)

Deprecated.

Returns a human readable name localized for the specified locale.

Specified by:

getName in class MapProjection

transformNormalized

protected java.awt.geom.Point2D transformNormalized(double x,
                                                    double y,
