Method Detail

doInverseProjection

public javax.vecmath.Point2d doInverseProjection(double x,
                                                 double y)
                                          throws ProjectionException
Description copied from class: Projection
Do an inverse projection from projected (map) coordinates to geographic coordinates.

Specified by:
doInverseProjection in class Projection
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.

doProjection

public javax.vecmath.Point2d doProjection(double lambda,
                                          double phi)
                                   throws ProjectionException
Description copied from class: Projection
The actual transform method doing a projection from geographic coordinates to map coordinates.

Specified by:
doProjection in class Projection
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.

getImplementationName

public java.lang.String getImplementationName()
Specified by:
getImplementationName in class Projection
Returns:
A deegree specific name which will be used for the export of a projection.
