Method Detail

project

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

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.

out - 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

getEPSGCode

public int getEPSGCode()

Returns the ESPG code for this projection, or 0 if unknown.

Overrides:

getEPSGCode in class Projection

toString
