메소드	설명
Boundary ( ) : Geometry	Returns the closure of the combinatorial boundary of this Geometry. The combinatorial boundary is defined as described in section 3.12.3.2 of [1]. Because the result of this function is a closure, and hence topologically closed, the resulting boundary can be represented using representational geometry primitives
Buffer ( double d ) : Geometry	Returns a geometry that represents all points whose distance from this Geometry is less than or equal to distance. Calculations are in the Spatial Reference System of this Geometry.
Clone ( ) : Polygon	Return a copy of this geometry
ConvexHull ( ) : Geometry	Geometry—Returns a geometry that represents the convex hull of this Geometry.
Difference ( Geometry geom ) : Geometry	Returns a geometry that represents the point set difference of this Geometry with anotherGeometry.
Distance ( Geometry geom ) : double	Returns the shortest distance between any two points in the two geometries as calculated in the spatial reference system of this Geometry.
Equals ( Polygon p ) : bool	Determines if this Polygon and the specified Polygon object has the same values
GetBoundingBox ( ) : BoundingBox	Returns the bounding box of the object
GetHashCode ( ) : int	Serves as a hash function for a particular type. GetHashCode is suitable for use in hashing algorithms and data structures like a hash table.
InteriorRing ( int N ) : LinearRing	Returns the Nth interior ring for this Polygon as a LineString This method is supplied as part of the OpenGIS Simple Features Specification
Intersection ( Geometry geom ) : Geometry	Returns a geometry that represents the point set intersection of this Geometry with anotherGeometry.
IsEmpty ( ) : bool	If true, then this Geometry represents the empty point set, Ø, for the coordinate space.
IsSimple ( ) : bool	Returns 'true' if this Geometry has no anomalous geometric points, such as self intersection or self tangency. The description of each instantiable geometric class will include the specific conditions that cause an instance of that class to be classified as not simple.
Polygon ( ) : System	Instatiates a polygon
Polygon ( LinearRing exteriorRing ) : System	Instatiates a polygon based on one extorier ring.
Polygon ( LinearRing exteriorRing, List interiorRings ) : System	Instatiates a polygon based on one extorier ring and a collection of interior rings.
SymDifference ( Geometry geom ) : Geometry	Returns a geometry that represents the point set symmetric difference of this Geometry with anotherGeometry.
TransformToImage ( SharpMap map ) : System.Drawing.PointF[]	Transforms the polygon to image coordinates, based on the map
Union ( Geometry geom ) : Geometry	Returns a geometry that represents the point set union of this Geometry with anotherGeometry.
