Constructor Detail

CylindricalEqualAreaProjection

public CylindricalEqualAreaProjection()

CylindricalEqualAreaProjection

public CylindricalEqualAreaProjection(double projectionLatitude,
                                      double projectionLongitude,
                                      double trueScaleLatitude)

Method Detail

initialize

public void initialize()

Description copied from class: Projection

Initialize the projection. This should be called after setting parameters and before using the projection. This is for performance reasons as initialization may be expensive.

Overrides:

initialize in class Projection

project

public Point2D.Double project(double lam,
                              double phi,
                              Point2D.Double xy)

Description copied from class: Projection

The method which actually does the projection. This should be overridden for all projections.

Overrides:

project in class Projection

Parameters:

lam - Longitude in radians.

phi - Latitude in radians.

xy - The projected point.

Returns:

The projected point, identical to parameter dst.

projectInverse

public Point2D.Double projectInverse(double x,
                                     double y,
                                     Point2D.Double lp)

Description copied from class: Projection

The method which actually does the inverse projection. This should be overridden for all projections.

Overrides:

projectInverse in class Projection

hasInverse

public boolean hasInverse()

Description copied from class: Projection

Returns true if this projection has an inverse

Overrides:

hasInverse in class Projection

isEqualArea

public boolean isEqualArea()

Description copied from class: Projection

Returns true if this projection is equal area

Overrides:

isEqualArea in class Projection

toString

public String toString()

Overrides:

toString in class CylindricalProjection
