Remarks
The interior of a point is the point itself, the boundary is the empty set, and the exterior is all other points.

A MapPoint is based upon the parent Geometry class. The Geometry class is immutable which means that you can not change its shape once it is created. If you need to modify a MapPoint once it has been created, use the MapPointBuilder class instead. The MapPointBuilder.ToGeometry method will provide you with the MapPoint object.
