The LASzip LiDAR compressor packaged as a simple stand-alone assembly for easy inclusion of compression and decompression functionality into other software. It compresses LAS files into much more compact LAZ files and vice versa. The resulting files are around 7 - 20 percent of their original size.
To get the original LASzip just download the LAStools distribution which contains the LASlib as well as the LASzip sources together with the binaries of the popular LAStools software and some small example LAZ files.

To get the newest version of the C# port of the LASzip library, goto: https://github.com/seeseekey/laszip.net/
ATTENTION: This port is not a complete port of the LASzip library. It does not contain an example, and you can't write version 1 LAZ files, while reading version 1 is still possible.
