About Loading and Unloading LAS Files

LAS files can be in a loaded or unloaded state within a LIDAR Layer. In an unloaded state the LAS file is uninitialized in the layer and no points will be retrieved from the LAS file or displayed in the map. In a loaded state the LAS file is initialized within the layer and will return or display points if the map's display overlaps the extent or boundary of the file. The number of loaded LAS files do not affect the display performance of the LIDAR Layer.

Note: A noticeable pause will occur when opening an MXD document containing a LIDAR Layer with numerous loaded LAS files.
