getVector

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

Convert geographic lat, lon into a geocentric unit vector. The x-component points toward lat,lon = 0, 0. The y-component points toward lat,lon = 0, PI/2. The z-component points toward north pole.

Parameters:

lat - geographic latitude in radians.

lon - longitude in radians.

Returns:

3 component unit vector.
