clusterPolygons

Create Cluster Polygons S

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

The algorithm starts from a random point and if finds 2 points closer than the Cluster Tolerance to the start point creates an initial cluster polygon. As long as there is another point closer to the initial cluster polygon, it is joined to it. The function is suitable for creating elongated clusters for points representing linear spatial phenomenon.
See also the ClusterPolygonsC function which uses a different algorithm and creates Center based clusters.

Parameters

Expression	Explanation
Function Name	PointsToClusterPolygonsS
<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).
{Remove Holes}	A Boolean indicating whether the function to remove the holes created during the interpolation.

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, "PointsToClusterPolygonsS", "input dataset", "output dataset", "Cluster Tolearance", "Remove Holes"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "PointsToClusterPolygonsS" "input dataset" "output dataset" "Cluster Tolearance" "Remove Holes"
.NET using ETGWOutX.dll	PointsToClusterPolygonsS(input dataset, output dataset, Cluster Tolearance, Remove Holes)
ArcPy	arcpy.PointsToClusterPolygonsS(input dataset, output dataset, "Cluster Tolearance", "Remove Holes")

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.
