Class GeometryCombiner
Combines Geometrys to produce a GeometryCollection of the most appropriate type.
Inherited Members
Namespace: NetTopologySuite.Geometries.Utilities
Assembly: NetTopologySuite.dll
Syntax
public class GeometryCombinerRemarks
Input geometries which are already collections will have their elements extracted first.
No validation of the result geometry is performed. (The only case where invalidity is possible is where IPolygonal geometries are combined and result in a self-intersection).
