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.

Syntax

arcpy.3d.RemoveTerrainPyramidLevel(in_terrain, pyramid_level_resolution)
ParameterExplanationData Type
in_terrain

The terrain dataset to process.

Terrain Layer
pyramid_level_resolution

The pyramid level to be removed as specified by its resolution.

Double

Derived Output

NameExplanationData Type
derived_out_terrain

The updated terrain.

Code sample

RemoveTerrainPyramidLevel example 1 (Python window)

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

arcpy.RemoveTerrainPyramidLevel_3d("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.
