com.vividsolutions.jtsexample.technique.SearchUsingPreparedGeometryIndex

public class SearchUsingPreparedGeometryIndex
extends Object

Demonstrates use of PreparedGeometrys in a spatial index to optimize spatial search. The example creates a grid of circular polygons, packed into the 1 x 1 square. This set of polygons is spatially indexed as PreparedGeometrys in an STRtree index. A series of random points in the square is generated, and the index is used to determine whether each point intersects any circles. The fraction of points which intersect will approximate the fraction of area covered by the circles.
