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
andGnomonic.Reverse
and it always includes the fields x, y, azi. and rk.
