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
