Class GnomonicData

java.lang.Object

com.irurueta.navigation.geodesic.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(double, double, double, double) and Gnomonic.reverse(double, double, double, double) and it always includes the fields x, y, azi, and rk.
