Public Methods

Method	Description
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 ( ) : MultiPolygon	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.
Geometry ( int N ) : Geometry	Returns an indexed geometry in the collection
GetBoundingBox ( ) : BoundingBox	Returns the bounding box of the object
GetEnumerator ( ) : IEnumerator	Gets an enumerator for enumerating the geometries in the GeometryCollection
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.
MultiPolygon ( ) : System	Instantiates a MultiPolygon
SymDifference ( Geometry geom ) : Geometry	Returns a geometry that represents the point set symmetric difference of this Geometry with anotherGeometry.
Union ( Geometry geom ) : Geometry	Returns a geometry that represents the point set union of this Geometry with anotherGeometry.
this ( int index ) : Polygon	Returns an indexed geometry in the collection

Method Details

Boundary() public method

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

public Boundary ( ) : Geometry
return	Geometry

Buffer() public method
