Class Polygon
A Polygon
is a planar Surface
representing a multisided geometry. It is defined by a single exterior boundary and zero or more interior boundaries, where each interior boundary defines a hole in the Polygon
.
Polygon
Examples
- On a region map,
Polygon
objects could represent forests, districts, and so on.
Polygon
Assertions
- The boundary of a
Polygon
consists of a set ofLinearRing
objects (that is,LineString
objects that are both simple and closed) that make up its exterior and interior boundaries. - A
Polygon
has no rings that cross. The rings in the boundary of aPolygon
may intersect at aPoint
, but only as a tangent. - A
Polygon
has no lines, spikes, or punctures. - A
Polygon
has an interior that is a connected point set. - A
Polygon
may have holes. The exterior of aPolygon
with holes is not connected. Each hole defines a connected component of the exterior.
The preceding assertions make a Polygon
a simple geometry.
