Set up a projection suitable for State Plane Coordinates.

Method Detail

clone

public Object clone()

Overrides:

clone in class Projection

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

getRowFromNearestParallel

public int getRowFromNearestParallel(double latitude)

getZoneFromNearestMeridian

public int getZoneFromNearestMeridian(double longitude)

setUTMZone

public void setUTMZone(int zone)

project

public Point2D.Double project(double lplam,
                              double lpphi,
                              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:

lplam - Longitude in radians.

lpphi - 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 out)

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

isConformal

public boolean isConformal()

Description copied from class: Projection

Returns true if this projection is conformal

Overrides:

isConformal in class Projection

isRectilinear

public boolean isRectilinear()

Description copied from class: Projection

Returns true if lat/long lines form a rectangular grid for this projection. This is generally only the case for cylindrical projections, but not for oblique cylindrical projections.

Overrides:

isRectilinear in class CylindricalProjection

toString

public String toString()

Overrides:

toString in class CylindricalProjection
