Public Methods

	Name	Description
	AccelerateForRelationalOperations	Produces a copy of the given geometry that is an accelerated geometry used to speed up relational operations. Only polyline and polygon geometries can be accelerated. If the geometry cannot be accelerated, the method returns the same input geometry.
	Area	Gets the area of the geometry. This is a planar measurement using 2D Cartesian mathematics to compute the area.
	AutoComplete	Constructs a polygon that fills in the gaps between the existing polygon and polyline.
	Boundary	Calculates the boundary of the input geometry.
	Buffer	Overloaded.
	CalculateNonSimpleMs	Calculates M attribute values for each non-simple (NaN) M-value from existing simple (non-NaN) M attributes on the specified geometry. The non-simple M values are obtained by extrapolation/interpolation for polylines and interpolation for polygons.
	CalculateNonSimpleZs	Calculates Z attribute values for each non-simple (NaN) Z-value from existing simple (non-NaN) Z attributes on the specified geometry. The non-simple Z values are obtained by extrapolation/interpolation for polylines and interpolation for polygons.
	CalibrateByMs	Calibrates M values using M values of input points.
	CenterAt	Center the envelope at the specified x and y coordinates.

	ConstructMultipatchExtrudeToZ	Creates a multipatch from the input polygon or polyline.
	Contains	Returns true if geometry1 contains geometry2.
	ConvexHull	Constructs the convex hull of the geometry.
	Crosses	Returns true if geometry1 crosses geometry2.

	Difference	Performs the topological difference operation on the two geometries.
	Disjoint	Returns true if geometry1 and geometry2 are disjoint.
	Disjoint3D	Returns true if geometry1 and geometry2 are disjoint in a 3-dimensional manner.
	Distance	Measures the planar distance between two geometries.

	ExportToWKT	Writes an OGC well-known text formatted version of the input geometry to a string.
	Extend	Performs the extend operation on a polyline using a polyline as the extender. The output polyline will have the first and last segment of each part extended to the extender if the segments can be interpolated to intersect the extender. In the case that the segments can be extended to multiple segments of the extender, the shortest extension is chosen. Only end points for parts that are not shared by the end points of other parts will be extended. If the polyline cannot be extended by the input extender, then a null will be returned.
	Generalize	Performs the generalize operation on the geometry.
	Generalize3D	Performs the generalize operation on the geometry.
	GeodesicArea	Gets the geodesic area of a polygon.
	GeodesicBuffer	Overloaded.
	GeodesicDistance	Calculates the geodesic distance between two geometries.
	GeodesicEllipse	The function returns a piecewise approximation of a geodesic ellipse (or geodesic circle, if semiAxis1Length = semiAxis2Length). Constructs a geodesic ellipse centered on the specified point. If this method is used to generate a polygon or a polyline, the result may have more than one part, depending on the size of the ellipse and its position relative to the horizon of the coordinate system. When the method generates a polyline or a multipoint, the result vertices lie on the boundary of the ellipse. When a polygon is generated, the interior of the polygon is the interior of the ellipse, however the boundary of the polygon may contain segments from the spatial reference horizon, or from the GCS extent.
	GeodesicLength	Gets the geodesic length of the input geometry.
	GeodesicSector	The function returns a piecewise approximation of a geodesic ellipse (or geodesic circle, if SemiAxis1Length = SemiAxis2Length). Constructs a geodesic ellipse centered on the specified point. If this method is used to generate a polygon or a polyline, the result may have more than one part, depending on the size of the sector and its position relative to the horizon of the coordinate system. When the method generates a polyline or a multipoint, the result vertices lie on the boundary of the ellipse. When a polygon is generated, the interior of the polygon is the interior of the sector, however the boundary of the polygon may contain segments from the spatial reference horizon, or from the GCS extent.

	GeodeticDensifyByLength	Creates geodetic segments connecting existing vertices and densifies the segments.

	GetMinMaxM	Gets the minimum and maximum M value.
	GetMMonotonic	Determines whether Ms are monotonic, and if so, whether they are ascending or descending.

	NearestPoint3D	Finds the nearest point, in 3D space, on a z-aware geometry to a specified point.
	NearestVertex	Finds the nearest vertex in the geometry to a specified point.
	NormalizeCentralMeridian	Folds the geometry into a range of 360 degrees. This may be necessary when wrap around is enabled on the map. If geometry is an Envelope then a Polygon will be returned unless the Envelope is empty in which case an empty Envelope will be returned.
	Offset	Returns offset version of the input geometry. The offset operation creates a geometry that is a constant distance from an input polyline or polygon. It is similar to buffering, but produces a one sided result. If offset distance > 0, then the offset geometry is constructed to the right of the oriented input geometry, otherwise it is constructed to the left. For a simple polygon, the orientation of outer rings is clockwise and for inner rings it is counter clockwise. So the "right side" of a simple polygon is always its inside. The bevelRatio is multiplied by the offset distance and the result determines how far a mitered offset intersection can be from the input curve before it is beveled.

	Project	Projects the given geometry to a new spatial reference. Same as GeometryEngine.ProjectEx(geometry, ProjectionTransformation.Create(geometry.SpatialReference, outputSpatialReference)); or, if both spatial references have vertical coordinate systems same as GeometryEngine.ProjectEx(geometry, ProjectionTransformation.CreateWithVertical(geometry.SpatialReference, outputSpatialReference));
