摘要
从 terrain 数据集中移除金字塔等级。
用法
除了表示全分辨率金字塔的等级 0 之外，任何金字塔等级都可以移除。
在 企业、工作组或 desktop 地理数据库 数据库中使用时，输入 terrain 将无法注册为版本。
语法
RemoveTerrainPyramidLevel_3d (in_terrain, pyramid_level_resolution)
| 参数 | 说明 | 数据类型 |
in_terrain | 待处理的 terrain 数据集。 | Terrain Layer |
pyramid_level_resolution | 要移除的由分辨率指定的金字塔等级。 | Double |
代码实例
RemoveTerrainPyramidLevel 示例 1（Python 窗口）
下面的示例演示了如何在 Python 窗口中使用此工具。
import arcpy
from arcpy import env
arcpy.CheckOutExtension("3D")
env.workspace = "C:/data"
arcpy.RemoveTerrainPyramidLevel_3d("sample.gdb/featuredataset/terrain", 10)
RemoveTerrainPyramidLevel 示例 2（独立脚本）
下面的示例演示了如何在独立 Python 脚本中使用此工具。
'''****************************************************************************
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.
