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.
