http://www.billburmaster.com/rmsandw/illinois/us/us14cookil.html WebST_Intersects and ST_Contains give us two ways to look at whether or not two polygons, or a polygon and point or lines share space. With ST_Intersects, the geometries just have to overlap. With ST_Contains, the geometry for one feature has to be completely inside the geometry of the reference polygon.
