Code sample

ErasePoint Example 1 (stand-alone script)
# Name: ErasePoint_Example.py
# Description: Erase points inside polygon features

import arcpy
from arcpy import env
env.workspace="C:/data"
inFeatures="wells.shp"
removeFeatures="land.shp"
operationType="INSIDE"

arcpy.ErasePoint_edit(inFeatures, removeFeatures, operationType)
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
from arcpy import env
 
# Set environment settings
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")
