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)
Parameter | Explanation | Data 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
Name | Explanation | Data Type |
derived_out_terrain | The updated terrain. | Terrain Layer |
Code sample
The following sample demonstrates the use of this tool in the Python window.
arcpy.RemoveTerrainPyramidLevel_3d("c:/data/sample.gdb/featuredataset/terrain", 10)
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.
