<div>Hi Andrea,</div><div><br></div><div>Just a note of warning: </div><div><br></div>if you have a point x,y that is inside the hole (so it doesn't belong the the polygon), and you run some point in polygon query (intersection for example) you will get that it is no part of any polygon.... but if you convert the ring in two polygons using this method.... that point will become part of a polygon (the ex hole)... So if for example the polygon represent the field, the hole represent the water and the point is a boat, after the conversion (ring to more polygons) the boat would be drained.... ;)<div>
