Generalize

Generalize Polylines

Generalizes (reduces the number of vertices required to represent a polyline) the features of a polyline layer using the Douglas-Poiker algorithm

A polyline feature layer
Generalize tolerance (maximum offset) - the maximum distance that the generalized polyline will differ from the original one

New polyline feature class
- The output feature class will contain all the features of the original data set
- The attributes of the input data set are preserved.

Parameters

Expression	Explanation
Function Name	GeneralizePolylines
<input dataset>	A String representing the input layer. Must be of Polyline type.
<output dataset>	A String - the full name of the output layer.
<Generalize Tolerance>	A Double representing the Generalization tolerance (in the units of the spatial reference of the input 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, "GeneralizePolylines", "input dataset", "output dataset", "Generalize Tolerance"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "GeneralizePolylines" "input dataset" "output dataset" "Generalize Tolerance"
.NET using ETGWOutX.dll	GeneralizePolylines(input dataset, output dataset, Generalize Tolerance)
ArcPy	arcpy.GeneralizePolylines(input dataset, output dataset, "Generalize Tolerance")

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.
