Erase Point (Editing)
Summary
Deletes points from the input that are either inside or outside the Remove Features, depending on the Operation Type.
Illustration

Usage
-
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.

This tool modifies the input data. See Tools with no outputs for more information and strategies to avoid undesired data changes.

Code Sample
# Name: ErasePoint_Example.py # Description: Erase points inside polygon features # Requirements: # Author: ESRI 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
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. # Author: ESRI # 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")
