Class GeodesicData

java.lang.Object
com.irurueta.navigation.geodesic.GeodesicData
public class GeodesicData extends Object
The results of geodesic calculations. This is used to return the results for a geodesic between point 1 (lat1, lon1) and point 2 (lat2, lon2). Fields that have not been set will be filled with Double.NaN. The returned GeodesicData objects always include the parameters provided to Geodesic.direct(double, double, double, double) and Geodesic.inverse(double, double, double, double) and it always includes the field a12.
