Generates a Voronoi diagram or Thiessen polygon. A Voronoi diagram is a set of polygons that represent proximity information about a set of input points. Each polygon in the diagram defines the area of space that is closest to a particular input point.
If a Voronoi diagram is to be made from points with elevations, and you want to add additional breakline and tolerance options, consider using the SurfaceModeller transformer.
This parameter allows groups to be formed by attribute values. Zero or more attributes may be specified.
Input features with the same attribute values are placed into the same group. The transformer then operates independently on each group of input features.
If this parameter is left blank, the transformer will treat the entire set of input features as one group.
If this parameter is set to Yes, which is the default, attributes from input points will be preserved on the output polygons.
If specified, this value limits the radius of the output polygons. This provides a way of generating a region of influence around each point.
