Class SearchUsingPreparedGeometryIndex
java.lang.Object
org.locationtech.jtsexample.technique.SearchUsingPreparedGeometryIndex
Demonstrates use of
PreparedGeometry
s 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.- Version:
