laszip

LASzip is a compression library that was developed by Martin Isenburg for compressing ASPRS LAS format data in his LAStools. 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.
