Class MultiPolygon

A MultiPolygon is a MultiSurface object composed of Polygon elements.

MultiPolygon Examples

• On a region map, a MultiPolygon could represent a system of lakes.

MultiPolygon Assertions

• A MultiPolygon has no two Polygon elements with interiors that intersect.
• A MultiPolygon has no two Polygon elements that cross (crossing is also forbidden by the previous assertion), or that touch at an infinite number of points.
• A MultiPolygon may not have cut lines, spikes, or punctures. A MultiPolygon is a regular, closed point set.
• A MultiPolygon that has more than one Polygon has an interior that is not connected. The number of connected components of the interior of a MultiPolygon is equal to the number of Polygon values in the MultiPolygon.

MultiPolygon Properties

• A MultiPolygon is a two-dimensional geometry.
• A MultiPolygon boundary is a set of closed curves (LineString values) corresponding to the boundaries of its Polygon elements.
• Each Curve in the boundary of the MultiPolygon is in the boundary of exactly one Polygon element.
• Every Curve in the boundary of an Polygon element is in the boundary of the MultiPolygon.
