Replace Terrain Points (3D Analyst)

Resumen

Replaces point features used in a terrain dataset with points from a specified feature class.

Uso

• The terrain data source can be points, multipoints, or embedded points.

• The replacement points can come from single-point or multipoint features.

• Replacing points in a terrain dataset will invalidate it. Run Build Terrain after adding points or multipoints.

• If the terrain is in SDE, it must be registered as versioned.

Ejemplo de código

ReplaceTerrainPoints 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.ReplaceTerrainPoints_3d("sample.gdb/featuredataset/terrain", "points_old", 
                            "sample.gdb/featuredataset/terrain/pts_new")

ReplaceTerrainPoints example 2 (stand-alone script)

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

'''****************************************************************************
Name: ReplaceTerrainPoints Example
Description: This script demonstrates how to use the 
             ReplaceTerrainPoints tool.
****************************************************************************'''

# Import system modules
import arcpy
from arcpy import env

# Obtain a license for the ArcGIS 3D Analyst extension
arcpy.CheckOutExtension("3D")

# Set environment settings
env.workspace = "C:/data"

# Set Local Variables
InTerrain = "sample.gdb/featuredataset/terrain"
TerrainFCl = "points_old"
InPoints = "sample.gdb/featuredataset/terrain/pts_new"

#Execute ReplaceTerrainPoints
arcpy.ReplaceTerrainPoints_3d(InTerrain, TerrainFCl, InPoints)
