Class KrovakProjection

java.lang.Object

org.locationtech.proj4j.proj.Projection

org.locationtech.proj4j.proj.KrovakProjection

All Implemented Interfaces:

Serializable, Cloneable

public class KrovakProjection
extends Projection

The Krovak projection. While Krovak defines parameters for the azimuth and the latitude of the pseudo-standard parallel, these are hardcoded in this implementation.

Constructor Details

KrovakProjection

public KrovakProjection()

Method Details

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 lplam,
 double lpphi,
 ProjCoordinate out)

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)

out - the projected coordinate (in coordinate system units)

Returns:

the target coordinate

projectInverse

protected ProjCoordinate projectInverse(double x,
 double y,
 ProjCoordinate dst)

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)

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

Returns:

the target coordinate

toString

public String toString()

Overrides:

toString in class Projection
