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. 
Syntax
ReplaceTerrainPoints(in_terrain, terrain_feature_class, in_point_features, {polygon_features_or_extent})| Parameter | Explanation | Data Type | 
| in_terrain | The terrain dataset to process. | Terrain Layer | 
| terrain_feature_class | The name of the terrain point feature class that will have some or all of its points replaced. | String | 
| in_point_features | The point or multipoint features that will replace the terrain point features. | Feature Layer | 
| polygon_features_or_extent (Optional) | An optional area of interest can be used to define the extent of the area in which the terrain points would be replaced. | Feature Layer; Extent | 
Derived Output
| Name | Explanation | Data Type | 
| derived_out_terrain | The updated input terrain. | Terrain Layer |
