PolylinetoPoint

Polylines To Points

Converts a polyline data set to a point dataset

A polyline feature layer
Conversion option
- Vertices - the vertices of all polylines will be converted to points. If the "Remove duplicate points" option is selected the duplicate points created from the nodes of two polylines sharing a common node will be represented by one point. Note that if this option is used the attempt to convert back these points to polylines will produce incorrect result.
- Nodes - only the nodes of each polyline will be exported.
- Middle points - only the middle point of each polyline will be exported.
More options
- Remove Duplicate Points - the duplicate points created from the vertices of two adjacent polygons will be represented by one point. Note that if this option is used the attempt to convert back these points to polygons will produce incorrect result
- Calculate point Position along boundaries
  - If used the [ET_Order] field will be populated with the relative location of the vertex (0 to 1) from the start of the polylines.
  - If not used, the [ET_Order] field will be populated with the order of the vertex in the polyline (from 0 to number of vertices)
- Preserve Z(M) available only if the input feature class is of PolygonZ(M) type. If selected, the result will be of PointZ(M) type, otherwise the result will be of plain points (no Z or M values)

See above for the use of the "Remove duplicate points" option
If the "Assign angle attribute" option is used, the points symbols can be rotated and in such a way can represent the direction of the polylines. See the example below

Parameters

Expression	Explanation
Function Name	PolylinesToPoints
<input dataset>	A String representing the input layer. Must be of Polyline type.
<output dataset>	A String - the full name of the output layer.
<Option>	A String - the convertion option. Valid values. "Vertex" "Node" "Middle"
{Calculate Angle}	A Boolean indicating whether the angle of the polyline at the points location to be calculated and stored in the attribute table. Used only for "Vertex" option.
{Remove Duplicates}	A Boolean indicating whether the duplicate points are to be removed from the output. Used only for "Vertex" option.
{Calculate Position}	A Boolean indicating whether the position of the points along the polygon boundary to be calculated. Used only for "Vertex" option.
{Keep Z}	A Boolean indicating whether if the input has Z values to keep them in the output.
{Keep M}	A Boolean indicating whether if the input has M values to keep them in the output.

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, "PolylinesToPoints", "input dataset", "output dataset", "Option", "Calculate Angle", "Remove Duplicates", "Calculate Position", "Keep Z", "Keep M"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "PolylinesToPoints" "input dataset" "output dataset" "Option" "Calculate Angle" "Remove Duplicates" "Calculate Position" "Keep Z" "Keep M"
.NET using ETGWOutX.dll	PolylinesToPoints(input dataset, output dataset, Option,Calculate Angle, Remove Duplicates, Calculate Position, Keep Z, Keep M)
ArcPy	arcpy.PolylinesToPoints(input dataset, output dataset,"Option", "Calculate Angle", "Remove Duplicates", "Calculate Position", "Keep Z", "Keep M")

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.
