Overrides:
hashCode in class java.lang.Object

dot

public static double dot(double[] v0,
                         double[] v1)

getVector

public static double[] getVector(double lat,
                                 double lon)

Parameters:
lat - geographic latitude in radians.
lon - longitude in radians.
Returns:
3 component unit vector.

getVector
