Generalize Method—ArcGIS Pro

Performs the generalize operation on the geometry.

Syntax

C#
Visual Basic (Declaration)

Geometry Generalize( 
   Geometry geometry,
   double maxDeviation,
   bool removeDegenerateParts,
   bool preserveCurves
)

Function Generalize( _
   ByVal geometry As Geometry, _
   ByVal maxDeviation As Double, _
   Optional ByVal removeDegenerateParts As Boolean, _
   Optional ByVal preserveCurves As Boolean _
) As Geometry

Parameters

geometry: The geometry to be generalized.
maxDeviation: The maximum distance in meters that the output geometry can deviate from the input geometry.
removeDegenerateParts: When true, the degenerate parts of the geometry will be removed from the output.
preserveCurves: (Optional) The default value is false.

Return Value

The generalized geometry.

Exceptions

Exception	Description
System.ArgumentNullException	Geometry is null or empty.
System.NotImplementedException	The method is not implemented for GeometryBag or Multipatch.
GeometryObjectException	The geomtry is of an incorrect type. (i.e. a point or multipoint).

Remarks

Generalize performs a Douglas-Peucker Generalization algorithm with a specified maximum offset tolerance given as input. For line segments, the generalized output is a subset of the original input vertices. For non-linear segments, if is false, then the generalized output contains points along all parts of the curve, not necessarily only the vertices. If is true, then the non-linear segments are left as is.
