spiderDiagram

Spider Diagram

Creates a polyline feature class representing the shortest distance between centers (point dataset) and Destinations (Point, Polyline or Polygon datasets). The Destinations are allocated to the closest Center.

Spider Diagram

Inputs:

Point feature layer representing the Centers
Point, Polyline or Polygon layer representing the destinations
Cutoff distance - the maximum distance between a Center and a Destination to be used. Destinations that a further than this distance from any Center will not be assigned to a Center
Output Spatial Reference from Centers or Destinations

Outputs:

New Polyline feature class. The attribute table of the resulting feature class will have three new fields
- [Center_ID] - the Feature ID of the Center point
- [Dest_ID] - the Feature ID of the Destination feature
- [ET_Dist] - the distance from the Center to the Destination

Parameters

Expression	Explanation
Function Name	SpiderDiagram
<Centers Dataset>	A String representing the input layer. Must be of Point type.
<Destinations Dataset>	A String representing the reference layer. Must be of Polyline type
<output dataset>	A String - the full name of the output layer.
< CutOff Distance>	A Double representing the Cut-Off distance to be used. The units of the tolerance are the units of spatial reference of the Centers Dataset if KeepSourceSref = TRUE. Otherwise - the units of spatial reference of the Destinations Dataset.
{KeepSourceSref}	A Boolean indicating whether the output to have the spatial reference of the input layer. If False or 0, the spatial reference of the reference layer will be used.

Running the function

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, "SpiderDiagram", "Centers Dataset", "Destinations Dataset", "output dataset", " CutOff Distance", "KeepSourceSref"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "SpiderDiagram" "Centers Dataset" "Destinations Dataset" "output dataset" "CutOff Distance" "KeepSourceSref"
.NET using ETGWOutX.dll	SpiderDiagram(Centers Dataset,Destinations Dataset, output dataset, CutOff Distance, KeepSourceSref)
ArcPy	arcpy.SpiderDiagram(Centers Dataset, Destinations Dataset, output dataset, "CutOff Distance", "KeepSourceSref")

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.
