Usage

Caution:

This tool modifies the input data. See Tools that do not create output datasets for more information and strategies to avoid undesired data changes.

• To delete points inside or on the boundary of the Remove Features, use operation type INSIDE. To delete points outside the Remove Features, use operation type OUTSIDE.

• For multipoint input features, only points inside or outside the Remove Features will be deleted, depending on the Operation Type.

Code sample

ErasePoint example 1 (Python window)

The following Python window script demonstrates how to use the ErasePoint function in immediate mode.

import arcpy
arcpy.env.workspace = "C:/data"
arcpy.ErasePoint_edit("trees.shp", "park_boundaries", "INSIDE")

ErasePoint example 2 (stand-alone script)

The following stand-alone script demonstrates how to use the ErasePoint function.

# Name: ErasePoint_Example2.py
# Description: Replacing low resolution elevation points inside 
# lake areas by high resolution lidar points.
 
# Import system modules
import arcpy
 
# Set environment settings
arcpy.env.workspace = "C:/data/Portland.gdb/relief"
 
# Set local variables
inElevationFeatures = "elevation_points"
inLidarFeatures = "lidar_points"
inLakeFeatures = "lakes"

# Erase elevation points inside lakes
arcpy.ErasePoint_edit(inElevationFeatures, inLakeFeatures, "INSIDE")

# Clip lidar points inside lakes
arcpy.ErasePoint_edit(inLidarFeatures, inLakeFeatures, "OUTSIDE")

# Append the clipped lidar points to the remaining elevation points
arcpy.Append_management(inElevationFeatures, inLidarFeatures, "NO_TEST")
