Method Detail

getGeographicCRS

IGeographicCRS getGeographicCRS()

Returns:

the underlyingCRS.

getProjection

IProjection getProjection()

Returns:

the projection.

doProjection

javax.vecmath.Point2d doProjection(double lambda,
                                   double phi)
                                   throws ProjectionException

The actual transform method doing a projection from geographic coordinates to map coordinates.

Parameters:

lambda - the longitude

phi - the latitude

Returns:

the projected Point or Point(Double.NAN, Double.NAN) if an error occurred.

Throws:

ProjectionException - if the given lamba and phi coordinates could not be projected to x and y.

doInverseProjection

javax.vecmath.Point2d doInverseProjection(double x,
                                          double y)
                                          throws ProjectionException

Do an inverse projection from projected (map) coordinates to geographic coordinates.

Parameters:

x - coordinate on the map

y - coordinate on the map

Returns:

the projected Point with x = lambda and y = phi;

Throws:

ProjectionException - if the given x and y coordinates could not be inverted to lambda and phi.
