Method Generalize

Generalize(Geometry, Double, Boolean)

Generalizes the given geometry by removing vertices based on the Douglas-Poiker algorithm.

Declaration

public static Geometry Generalize(this Geometry geometry, double maxDeviation, bool removeDegenerateParts)

Parameters

Type	Name	Description
Geometry	geometry	The geometry to be generalized.
System.Double	maxDeviation	The maximum distance that the generalized geometry can deviate from the original, in the same units as the geometry's spatial reference system.
System.Boolean	removeDegenerateParts	When true, the degenerate parts of the geometry are removed from the output (may be undesired for drawing).

Returns

Type	Description
Geometry	A Geometry that represents the generalization of the input geometry.

Remarks

Geometry is generalized by removing vertices based on the Douglas-Poiker algorithm. MapPoint and Multipoint geometries are left unchanged. Envelope is converted to a Polygon and then generalized. Supports true curves as input, producing a densified curve as output where applicable.

Relevant samples

Densify and generalize: A multipart geometry can be densified by adding interpolated points at regular intervals. Generalizing multipart geometry simplifies it while preserving its general shape. Densifying a multipart geometry adds more vertices at regular intervals.
