bufferPolygonsNoOverlaps

Buffer Polygons with No Overlaps

Buffers a group of neighboring polygons in such a way that:

A polygon feature layer
Buffer distance in the units of the spatial reference of the input dataset
Polygon ID Field. The values of this field should uniquely identify the input polygons. This field might be used to transfer all attributes from the input dataset to the output
Merge buffers option. If not selected, the output will represent only the buffered area. If selected, the input polygons will be merged with their corresponding buffers.
Precision. Indicates how well the output buffers will match the original polygons. The higher the precision is, the slower the process will be

New polygon layer
- The output layer depends on the "Merge buffers" option
- The values of the Polygon ID Field will be preserved.

It is highly recommended to use the Clean Polygons function before running this function.

Input polygons

Output Buffers - Merge Option = False (not selected)

Output Buffers - Merge Option = False (not selected) overlaid with the original polygons

Output Buffers - Merge Option = True ( selected). The red polyline is the outline of the original polygons.

Parameters

Expression	Explanation
Function Name	BufferPolygonsNoOverlaps
<input dataset>	A String representing the input layer. Must be of polygon type.
<output dataset>	A String - the full name of the output layer.
<Buffer Distance>	A Double. The buffer distance to be used.
<ID Field>	A String. The name of the field in the input dataset to be used.
<Merge>	A Boolean. Indicating whether the buffers to be merged to the original polygons.
{Precision}	A string indicating the precision of the output. Valid values - "Normal", "Medium", "High". Default value - "Normal"

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, "BufferPolygonsNoOverlaps", "input dataset", "output dataset", "Buffer Distance", "ID Field", "Merge", "Precision"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "BufferPolygonsNoOverlaps" "input dataset" "output dataset" "Buffer Distance" "ID Field" "Merge" "Precision"
.NET using ETGWOutX.dll	BufferPolygonsNoOverlaps(input dataset, output dataset, Buffer Distance, ID Field, Merge", Precision")
ArcPy	arcpy.BufferPolygonsNoOverlaps(input dataset, output dataset, "Buffer Distance" , "ID Field", "Merge", "Precision")

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.
