The idea (as I understand it - could be wrong) is to be able to use a (fast) bounding box to find the polygons to test, rather than having to test against every polygon using more complex algorithms. </div><div class=""><br class=""></div><div class="">I suppose you could consider that if you want to find out if a point is in one or more of your polygons, the benefit of having more index squares.
