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 |
