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 ProjCoordinate project(double lam,
                              double phi,
                              ProjCoordinate xy)

Description copied from class: Projection

Computes the projection of a given point (i.e. from geographics to projection space). This should be overridden for all projections.

Overrides:

project in class Projection

Parameters:

lam - the geographic x ordinate (in radians)

phi - the geographic y ordinatee (in radians)

xy - the projected coordinate (in coordinate system units)

Returns:

the target coordinate

projectInverse

public ProjCoordinate projectInverse(double x,
                                     double y,
                                     ProjCoordinate lp)

Description copied from class: Projection

Computes the inverse projection of a given point (i.e. from projection space to geographics). This should be overridden for all projections.

Overrides:

projectInverse in class Projection

Parameters:

x - the projected x ordinate (in coordinate system units)

y - the projected y ordinate (in coordinate system units)

lp - the inverse-projected geographic coordinate (in radians)

Returns:

the target coordinate

hasInverse

public boolean hasInverse()

Description copied from class: Projection

Tests whether this projection has an inverse. If this method returns true then the Projection.inverseProject(ProjCoordinate, ProjCoordinate) and Projection.inverseProjectRadians(ProjCoordinate, ProjCoordinate) methods will return meaningful results.

Overrides:

hasInverse in class Projection

Returns:

true if this projection has an inverse

isRectilinear

public boolean isRectilinear()

Description copied from class: Projection

Tests whether under this projection lines of latitude and longitude form a rectangular grid

Overrides:

isRectilinear in class Projection

toString

public java.lang.String toString()

Overrides:

toString in class Projection
