Class MapEnvelope

java.lang.Object

com.nutiteq.core.MapEnvelope

public class MapEnvelope
extends java.lang.Object

A bounding area on the map. Can be defined by a map bounds object or by a convex bounding polygon.
This class is intended for conservative object area estimation and fast intersection testing.
