GPTool

public class CreateThiessenPolygons
extends AbstractGPTool

Creates Thiessen polygons from point input features. The Create Thiessen Polygons tool is contained in the Analysis Tools tool box.

Usage tips:

• This tool is used to divide the area covered by the point input features into Thiessen or proximal zones. These zones represent full areas where any location within the zone is closer to its associated input point than to any other input point.
• The theoretical background for creating Thiessen polygons is as follows:
• Thiessen proximal polygons are constructed as follows:
• The outside boundary of the output Thiessen polygon feature class is the extent of the point input features plus an additional 10%. If the environment is set to a specific extent window, this tool tool will use the environment setting to set its outside boundary.
• This tool may produce unexpected results with data in a geographic coordinate system since the Delaunay triangulation method used by the tool works best with data in a projected coordinate system.
