Method Detail

toDegrees

public static double toDegrees(Angle dmsAngle)

Convert a degree-minutes-seconds angle to signed floating-point degrees.

Parameters:

dmsAngle - angle in degrees-minutes-seconds

Returns:

degrees in dmsAngle, accurate to within 0.0001 degrees, where angles north & east are positive and south & west are negative

displacement

public static Angle displacement(Angle begin,
                                 Angle end)

Angular displacement from begin to end. Returns an angle with smallest absolute value, for example like this:

Not this:

Parameters:

begin - starting angle, must be a valid latitude or longitude as defined in Angle

end - ending angle, must be a valid angle measuring the same coordinate (latitude or longitude) as begin

Returns:

angle with a smallest absolute value, measuring the same coordinate as the inputs, that sweeps from begin to end
