Remove Terrain Pyramid Level (3D Analyst)

Available with 3D Analyst license.

Summary

Removes a pyramid level from a terrain dataset.

Usage

• Any pyramid level can be removed except for level 0, which represents the full resolution pyramid.

• When used in an enterprise geodatabase, the input terrain cannot be registered as versioned.

Parameters

Input Terrain	The terrain dataset that will be processed.	Terrain Layer
Pyramid Level Resolution	The pyramid level to be removed as specified by its resolution.	Double

Derived Output

Label	Explanation	Data Type
Updated Input Terrain	The updated terrain.	Terrain Layer

Python

arcpy.ddd.RemoveTerrainPyramidLevel(in_terrain, pyramid_level_resolution)

Name	Explanation	Data Type
in_terrain	The terrain dataset that will be processed.	Terrain Layer
pyramid_level_resolution	The pyramid level to be removed as specified by its resolution.	Double

Code sample

RemoveTerrainPyramidLevel example 1 (Python window)

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

arcpy.ddd.RemoveTerrainPyramidLevel("c:/data/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.
