| Description | A geographic area of any type. An area is bounded by at least one polyline. It could also have a more complex shape with holes defined by inner polygons with islands in the holes with their own outer polygons. Areas may also include a set of polygons (multipolygon), each with its own exterior boundary as in a chain of islands. |
