Files conforming to the ASPRS LIDAR data exchange format standard are named with an LAS extension. The LAS file is intended to contain LIDAR point data records. The data will generally be put into this format from software (provided by LIDAR hardware vendors) which combines GPS, IMU, and laser pulse range data to produce X, Y, and Z point data.

In this specific case, the output is a LAS file. When readLAS() reads a chunk from the catalog the points in the buffer are flagged so they can be easily manipulated. Since they are flagged, we can easily remove these points by adding this step to our user-defined function. It is always the role of the user to remove the buffer of the output.The LAS File Viewer Applet was created to assist the user in locating and plotting well data, rock measured & observational data and formation tops data by depth.
