Hello, I have a question. If a multipolygon has inner "holes", are these holes part of the multipolygon? I mean, if I want to check if a given point is inside of a multipolygon (using "within" or "contains") and this point is in the hole, should "within" and "contains" return "true"?
Being more specific, I have a multypolygon that represents a forest, in a map. This multipolygon has a hole inside. Then, I have another multipolygon that fits exactly into the hole, and represents an airport. If I select a point from the airport, this point is inside the second multipolygon, of course, but should it be inside the first one too? Because my problem is that I have to decide if the point is part of the airport or part of the forest, and "within" and "contains" methods return both multipolygon, instead of only the second one (the airport). Maybe is more clear with an image: http://www.nebulared.com/tmp_geo/multipolygon.jpg Thanks in advance!
