Replace Terrain Points (3D Analyst)
Summary
Replaces point features used in 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.
If the terrain is in SDE, it must be registered as versioned.
Syntax
