Library for lossless LAS compression

LASzip is a compression library for compressing ASPRS LAS format data. It has been provided as an LGPL-licensed stand-alone software library to allow other softwares that handle LAS data to read and write LASzip-compressed data. The BSD-licensed libLAS and the LGPL-licensed LASlib can take advantage of LASzip to read and write compressed data.

LASzip is completely lossless. It compresses bulky LAS files into compact LAZ files that are only 10-20 percent of the original size, accurately preserving every single bit.
