Replace Terrain Points (3D Analyst)

Summary

Replaces points referenced by a terrain dataset with points from a specified feature class.

Usage

• 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.

Code sample

ReplaceTerrainPoints example 1 (Python window)

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

arcpy.env.workspace = "C:/data"
arcpy.ddd.ReplaceTerrainPoints("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.
