Summary
Deletes points within a specified area of interest from one or more features that participate in a terrain dataset.
Usage
Deleting points from an embedded feature class will invalidate the terrain. Run the Build Terrain tool after deleting points.
If the terrain is in an enterprise geodatabase, it must be registered as versioned.
Syntax
DeleteTerrainPoints(in_terrain, data_source, polygon_features_or_extent)
Parameter | Explanation | Data Type |
in_terrain | The terrain dataset to process. | Terrain Layer |
data_source [data_source,...] | One or more feature classes from which points will be removed. | String |
polygon_features_or_extent | Specifies the area from which points will be removed. A polygon feature class or an extent can be used. If extent values are desired, use an arcpy.Extent object. | Feature Layer; Extent |
Derived Output
Name | Explanation | Data Type |
derived_out_terrain | The updated terrain. | Terrain Layer |
Code sample
The following sample demonstrates the use of this tool in the Python window.
arcpy.env.workspace = "C:/data"

Name: Delete Terrain Outliers
Description: Uses Locate Outliers to identify outlier points in
a terrain dataset, and eliminates the outliers from the
terrain with Delete Terrain Points.
