PolygonN

Base Type: Polygon

A class for a polygon represented in normalized form.

Property	Type	Description
Extent	Envelope	Bounding extent of the polygon.
HasID	bool	True if the polygon is composed of points that define a id property.
HasM	bool	True if the polygon is composed of points that define an M (measure) property.
HasZ	bool	True if the polygon is composed of points that define a Z (3rd dimension) property.
RingArray	Ring[]	An array of rings that define the polygon.
SpatialReference	SpatialReference	The spatial reference associated with the polygon.

Remarks

This type should be used to construct a polygon and will be used when a service operation returns a polygon. See the Polygon discussion for more information.
