MultiPolygon
A MultiPolygon is a MultiSurface object composed of
Polygon elements.
MultiPolygon Examples
MultiPolygon could represent a system of lakes.
MultiPolygon Assertions
MultiPolygon has no two Polygon elements with interiors
that intersect.
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.
MultiPolygon may not have cut lines, spikes or punctures. A
MultiPolygon is a regular, closed point set.
MultiPolygon which has more than one Polygon has an
interior which 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
MultiPolygon is a two-dimensional geometry.
MultiPolygon boundary is a set of closed curves
(LineString values) corresponding to the boundaries of its
Polygon elements.
Curve in the boundary of the MultiPolygon is in the
boundary of exactly one Polygon element.
Curve in the boundary of an Polygon element is
in the boundary of the MultiPolygon.
