public class Bounds
extends Object

Methods for computing the latitudes and longitudes spanned by a set of points.

PS1 instructions: do NOT change the method signatures or specifications of these methods, but you should implement their method bodies, and you may add new public or private methods or classes if you like.

Method Detail

latitudeRange

public static List<Angle> latitudeRange(Set<PointOfInterest> pointsOfInterest)

Find minimum-area latitude range that encloses all points of interest.

Parameters:

pointsOfInterest - set of POIs, not modified by this method

Returns:

a new two-element list representing a minimum-area band of latitudes such that sweeping a latitude line from latitude list[0] NORTHWARD to latitude list[1] touches every point in pointsOfInterest

longitudeRange

public static List<Angle> longitudeRange(Set<PointOfInterest> pointsOfInterest)

Find minimum-area longitude range that encloses all points of interest.

Parameters:

pointsOfInterest - set of POIs, not modified by this method

Returns:

a new two-element list representing a minimum-area band of longitudes (also called a spherical lune) such that sweeping a longitude line from longitude list[0] EASTWARD to longitude list[1] touches every point in pointsOfInterest
