Summary
Removes one or more LAS files and surface constraint features from a LAS dataset.
Usage
File paths must use the folder separator associated with the operating system.
Only a folder that directly contains LAS files can be provided as an input. When a folder is specified, all LAS files that reside in that folder will be removed from the LAS dataset.
Surface constraint features only have to be cited by their name. For example, boundary.shp and sample.gdb/boundary would just be referred to as boundary.
Syntax
RemoveFilesFromLasDataset(in_las_dataset, {in_files}, {in_surface_constraints})
Parameter | Explanation | Data Type |
in_las_dataset | The LAS dataset to process. | LAS Dataset Layer |
in_files [in_files,...] (Optional) | The name of the LAS files or folders containing LAS files whose reference will be removed from the LAS dataset. | String |
in_surface_constraints [in_surface_constraints,...] (Optional) | The name of the surface constraint features that will be removed from the LAS dataset. | String |
Derived Output
Name | Explanation | Data Type |
derived_las_dataset | The updated LAS dataset. | LAS Dataset Layer |
Code sample
RemoveFilesFromLasDataset example 1 (Python window)
The following sample demonstrates the use of this tool in the Python window.
