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.
# 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
