Summary
Removes one or more LAS files and surface constraint features from a LAS dataset.
Usage
When a folder is specified for removal, all LAS files that reside in the 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_management (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 |
Code sample
RemoveFilesFromLasDataset example 1 (Python window)
The following sample demonstrates the use of this tool in the Python window.
import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.RemoveFilesFromLasDataset_management("test.lasd",
"LA_N; LA_S/LA_5S4E.las",
"boundary.shp; streams.shp")
RemoveFilesFromLasDataset example 2 (stand-alone script)
The following sample demonstrates the use of this tool in a stand-alone Python script.
