A spatial index is calculated and added to the LAS auxiliary files when statistics are calculated.What is a LAS file? A LAS file contains Light Detection and Ranging (LIDAR) data that was collected by optical remote sensors. The data is saved in a standard format developed by the American Society for Photogrammetry and Remote Sensing (ASPRS). American military and scientific agencies use LAS files to share LIDAR data with each other.Log ASCII Standard, LAS, is a format specification for storing and distributing digital well log data.
