Renode Wizard

Renode Polylines

Analyzes the nodes of a polyline layer and exports them as a point feature class. Creates links between the nodes and corresponding polylines

New point feature class
- Contains points representing polyline nodes
  - Regular nodes - node where more than two polylines intersect
  - Pseudo nodes - occur where a single line connects with itself or where only two polylines intersect
  - Dangling nodes - unconnected nodes of dangling polylines
- Two fields are added to the point attribute table :
  - [ET_Type] - the type of node.
  - [ET_Valency] - the number of polylines that connect in the node. For a Dangling node Valency = 1, for a Pseudo node Valency = 2, for a Regular node Valency >=3
  - [ET_NodeId] - the ID of the nodes allowing link to the original polylines
A copy of the original polyline layer with two fields are added to the polyline attribute table
- [ET_FNode] - the id of the From Node of the polyline - links to a point in the Node feature class
- [ET_TNode] - the id of the To Node of the polyline - links to a point in the Node feature class

Parameters

Expression	Explanation
Function Name	RenodePolylines
<input dataset>	A String representing the input layer.
<Output Node Dataset>	A String - the full name of the output Nodes layer.
<Output Polyline Dataset>	A String representing the output polyline layer.

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, "RenodePolylines", "input dataset", "Output Node Dataset", "Output Polyline Dataset"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "RenodePolylines" "input dataset" "Output Node Dataset" "Output Polyline Dataset"
.NET using ETGWOutX.dll	RenodePolylines(input dataset, Output Node Dataset,Output Polyline Dataset)
ArcPy	arcpy.RenodePolylines(input dataset, Output Node Dataset,Output Polyline Dataset)

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.
