Class TrapezoidPositionPredictor

  • All Implemented Interfaces:
    ISTSearchAreaProducer
    public class TrapezoidPositionPredictor
extends Object
implements ISTSearchAreaProducer
    Predicts the position of points and polygons based upon the differential rotation of the sun, or a given normalized movement vector. Similarly, this file also produces a search based upon the polygon representation or the mbr of an object. The search are is a trapezoid that starts as the size of the mbr at the left and opens up to the right.
