Method Detail

project

public ProjCoordinate project(double lplam,
                              double lpphi,
                              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:

lplam - the geographic x ordinate (in radians)

lpphi - the geographic y ordinatee (in radians)

xy - the projected coordinate (in coordinate system units)

Returns:

the target coordinate

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

isEqualArea

public boolean isEqualArea()

Returns true if this projection is equal area

Overrides:

isEqualArea in class Projection

Returns:

true if this projection is equal-area

setW

public void setW(double w)

getW

public double getW()

setM

public void setM(double m)

getM

public double getM()

toString

public String toString()

Overrides:

toString in class PseudoCylindricalProjection

equals

public boolean equals(Object that)

Description copied from class: Projection

Represents quality between possible outputs of Projection.project(ProjCoordinate, ProjCoordinate). Subclasses of Projection should capture additional state that is used in the project method and delgate to base. Note: The name of the projection is not part of equality.

Overrides:

equals in class Projection

hashCode

public int hashCode()

Description copied from class: Projection

Hash of those fields considered in Projection equalituy. Subclasses that override equality should override hashCode.

Overrides:

hashCode in class Projection
