clusterPolygonsC

Create Cluster Polygons C

Delineates cluster polygon for the input points based on user specified cluster distance.

The algorithm tries first to find the centers for the clusters of points and then assigns to these centers the points located within the cluster tolerance.
See also the ClusterPolygonsS function which uses a different algorithm and is able to create elongated clusters.

Parameters

Expression	Explanation
Function Name	PointsToClusterPolygonsC
<input dataset>	A String representing the input layer. Must be of Point type.
<output dataset>	A String - the full name of the output layer.
<Cluster Tolearance>	A Double representing the Cluster Tolearance( in the units of the spatial reference of the input dataset).
<Polygon Type>	A String indicating the type of cluster polygons to be created. Valid options - "Convex","ConcaveC" - conservative, "ConcaveA" - aggressive.

ETGWPath used in the table below is the full path to ETGWRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETGeo Wizards\ETGWRun.exe")

Language	Syntax
Python	subprocess.call([ETGWPath, "PointsToClusterPolygonsC", "input dataset", "output dataset", "Cluster Tolearance", "Polygon Type"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "PointsToClusterPolygonsC" "input dataset" "output dataset" "Cluster Tolearance" "Polygon Type"
.NET using ETGWOutX.dll	PointsToClusterPolygonsC(input dataset, output dataset, Cluster Tolearance, Polygon Type)
ArcPy	arcpy.PointsToClusterPolygonsC(input dataset, output dataset, "Cluster Tolearance", "Polygon Type")

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
