Create LAS Dataset In Arcgis
Create LAS Dataset on ArcGis for Desktop
Similar to a mosaic dataset, the LAS dataset simply references files on disk. This allows for minimizing required storage space as well as limiting redundancies in your data. However, it is always recommended to keep an archive of your LAS files. Any changes to point classifications made in the LAS dataset will apply to the native LAS file as well. These changes are irreversible; therefore maintaining a collection of backup LAS files is prudent.
