LAS file extension - LIDAR data exchange

What is las file? How to open las files?

File type specification:

GIS, GPS navigation and map file type icon GIS, GPS navigation and map file type

The las file extension is associated with the LIDAR data exchange file format.

The 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. The intention of the data format is to provide an open format which allows different LIDAR vendors to output data into a format which a variety of LIDAR software vendors can use. Software that creates the LAS file will be referred to as “generating software”, and software that reads and writes to the LAS file will be referred to as “user software” within this specification.

The format contains binary data consisting of a header block, variable length records, and point data. All data is in little-endian format. The header block consists of a public block followed by variable length records. The public block contains generic data such as point numbers and coordinate bounds. The variable length records contain variable types of data including projection information, metadata, and user application data.
