All Implemented Interfaces:

java.lang.Comparable<Altitude>, I_Unitable<Altitude>

public class Altitude
extends java.lang.Object
implements I_Unitable<Altitude>

Defines an altitude. The units are assumed to be feet, but no calculations rely on this. It allows negative values to support delta values.
