Erase

Clip

Running programmatically

Erases a feature layer with the features of a polygon layer

Inputs:

Layer to be erased - a Point, Multipoint, Polyline or Polygon layer
Erase layer - a polygon layer which features will be used for clipping

Outputs:

New layer (Point, Multipoint, Polyline or Polygon depending on the type of the original layer)
- The attributes are preserved
- The spatial reference of the input data set is preserved

Examples:

Running Programmatically

Parameters

Expression	Explanation
Function Name	EraseSingle
<input dataset>	A String representing the input layer.
<Erase Dataset>	A String representing the layer to be merged. Must be of Polygon type.
<output dataset>	A String - the full name of the output layer.

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, "EraseSingle", "input dataset", "Erase Dataset", "output dataset"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "EraseSingle" "input dataset" "Erase Dataset" "output dataset"
.NET using ETGWOutX.dll	EraseSingle(input dataset, Erase Dataset, output dataset)
ArcPy	arcpy.EraseSingle(input dataset, Erase Dataset, "output 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.
