  +--com.AndrewGray.geoutils.MercatorMap

public final class MercatorMap

extends java.lang.Object

class defines a notional perfect mercator map with specified width and height. Used in conjunction with MapPoint to allow the conversion between mercator x,y coordinates and LatLongs.
The map supports re-sizing after it it created. Upon any resize operation all currently defined mappoints are recomputed based on their LatLong.
