Summary

Deletes points from the input that are either inside or outside the Remove Features, depending on the Operation Type.

Illustration

Usage

Caution:

This tool modifies the input data. See Tools with no outputs 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.

Syntax

ErasePoint_edit (in_features, remove_features, {operation_type})

Parameter	Explanation	Data Type
in_features	The input point features.	Feature Layer
remove_features	Input features inside or outside the Remove Features will be deleted, depending on the Operation Type parameter.	Feature Layer
operation_type (Optional)	Determines if points INSIDE or OUTSIDE the Remove Features will be deleted. INSIDE —Input point features inside or on the boundary of the Remove Features will be deleted. OUTSIDE —Input point features outside the Remove Features will be deleted.	String

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"
try:
    arcpy.ErasePoint_edit(inFeatures, removeFeatures, operationType)
except Exception, e:
    # If an error occurred, print line number and error message
    import traceback, sys
    tb = sys.exc_info()[2]
    print "Line %i" % tb.tb_lineno
    print e.message

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")
