Class GnomonicData

java.lang.Object

net.sf.geographiclib.GnomonicData

public class GnomonicData
extends Object

The results of gnomonic projection.

This is used to return the results for a gnomonic projection of a point (lat, lon) given a center point of projection (lat0, lon0). The returned GnomonicData objects always include the parameters provided to Gnomonic.Forward and Gnomonic.Reverse and it always includes the fields x, y, azi. and rk.
