RemoveTerrainPyramidLevel example 1 (Python window)

The following sample demonstrates the use of this tool in the Python window:

import arcpy
from arcpy import env

arcpy.CheckOutExtension("3D")
env.workspace = "C:/data"
arcpy.RemoveTerrainPyramidLevel_3d("sample.gdb/featuredataset/terrain", 10)
RemoveTerrainPyramidLevel example 2 (stand-alone script)

The following sample demonstrates the use of this tool in a stand-alone Python script:

'''****************************************************************************
Name: RemoveTerrainPyramidLevel Example
Description: This script demonstrates how to add new 
             points to a terrain with the DeleteTerrainPoints tool, then use 
             the ChangeTerrainReferenceScale and RemoveTerrainPyramidLevel to
             to adjust the pyramids for reducing the amount of data stored for 
             providing an optimized display performance.
