Buffer

Creates buffer polygons from the features of the input dataset. The buffer distance (in the units of the spatial reference of the input dataset) can be entered as a number (equal for all input features)or a numeric field.

Inputs:

A point, multipoint, polyline or polygon feature layer
Buffer distance - a number (the same buffer distance will be used for all input polylines) or the name of a numeric field in the polyline attribute table that has the buffer distance for each input polyline.
Dissolve option - the boundaries of the intersecting buffers will be dissolved. The original attributes will not be preserved if the dissolve option is used.

Outputs:

New polygon feature class

Notes :

The attributes of the input features will be transferred to the resulting polygons only if the Dissolve option is NOT used.
For advanced buffering of polylines see the Buffer Polylines function.

Parameters

Expression	Explanation
Function Name	Buffer
<input dataset>	A String representing the input layer.
<output dataset>	A String - the full name of the output layer.
{Buffer Distance}	A Double representing the buffer distance in the units of the Spatial Reference of the input layer.
{Buffer Field}	A String representing the name of a field in the in the attribute table of the input dataset. The field has the values for the buffer distance.
{Dissolve Buffers}	A Boolean. If True - the boundaries of the intersecting buffers will be dissolved.
{Dissolve Fields}	A String representing a list (separated with ";") with the field names to be used for dissolving.
{Statistic Fields}	A String representing a list (separated with ";") with the field names for which statistics will be created. Example: "Field1 Sum;Field2 Max;Field3 Min"
{Create Multiparts}	A Boolean indicating whether the function will create multipart polygons.

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, "Buffer", "input dataset", "output dataset", "Buffer Distance", "", "Dissolve Buffers", "Dissolve Fields", "Statistic Fields", "Create Multiparts"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "Buffer" "input dataset" "output dataset" "Buffer Distance" "" "Dissolve Buffers" "Dissolve Fields" "Statistic Fields" "Create Multiparts"
.NET using ETGWOutX.dll	Buffer(input dataset, output dataset, Buffer Distance, "", Dissolve Buffers, Dissolve Fields, Statistic Fields, Create Multiparts)
ArcPy	arcpy.Buffer(input dataset, output dataset, "Buffer Distance", "", "Dissolve Buffers", "Dissolve Fields", "Statistic Fields", "Create Multiparts")

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.
