Class Angle

java.lang.Object

geo.Angle

public class Angle
extends Object

Immutable datatype representing an angle in a geographic coordinate system, measured in degrees, minutes (1/60ths of a degree), and seconds (1/60ths of a minute). Angles can be used for many purposes, but for some uses, only certain angles are valid:

• Valid angles for latitude range from 0 to 90 deg N or S, inclusive. Note that 0 deg N & S are different representations of the same latitude (equator).
• Valid angles for longitude range from 0 to 180 deg E or W, inclusive. 0 deg E & W are different representations of the same longitude (prime meridian), and 180 deg E & W are also different representations of the same longitude (antimeridian).
• Valid angles for displacement range from 0 to 180 deg, inclusive.

PS1 instructions: do NOT change this class.
