The LAS file is intended to contain LIDAR point data records. The data will generally be put into this format from software (e.g. provided by LIDAR hardware vendors) which combines GPS, IMU,and laser pulse range data to produce X, Y, and Z point data. The intention of the data format is to provide an open format that allows different LIDAR hardware and software tools to output data in a common format.
The American Society for Photogrammetry & Remote Sensing (ASPRS) is the owner of the LAS Specification. The standard is maintained by committees within the organization as directed by the ASPRS Board of Directors. Questions related to this standard can be directed to ASPRS at 301-493-0290, by email at firstname.lastname@example.org, or by mail at 5410 Grosvenor Lane, Suite 210, Bethesda, Maryland 20814-2160
