79The LGPL-licensed LASzip library is easiest integrated via the DLL that is in
80the LASzip subdirectory of the `LAStools`_ distribtion. Other options are to
81link LASzip via the BSD-licensed `libLAS`_ library or to work with the `LASlib`_
82library which fully integrates and enhances the LASzip codebase with spatial
83indexing, filters, transforms, geo-referencing, ... of LAS and LAZ files.

90  - See `OSGeo4W`_ for Windows .lib and
91    include files to compile LASzip into your own application. `libLAS`_
92    binaries through `OSGeo4W`_ also link LASzip.
93
94  - For explicit compression (decompression) of LAS (LAZ) files a Windows
95    binary `laszip.exe`_ is available (command-line only `laszip-cli.exe`_),
96    as well as source code, examples, and makefiles to build your
97    own `LASzip`_ on Windows, Linux, or MacOS.

112Background
113------------------------------------------------------------------------------
114
115LASzip is a compression library that was developed by `Martin Isenburg`_ for
116compressing `ASPRS LAS format`_ data in his `LAStools`_. It has been provided
117as an `LGPL`_-licensed stand-alone software library to allow other softwares
118that handle LAS data to read and write LASzip-compressed data. The BSD-licensed
119`libLAS`_ and the LGPL-licensed `LASlib`_ can take advantage of LASzip to read
120and write compressed data.
121
122LASzip is completely lossless. It compresses bulky LAS files into compact LAZ
123files that are only 7-20 percent of the original size, accurately preserving
124every single bit. For example, compressing and decompressing the LAS file
125lidar.las with `laszip.exe`_ (command-line only `laszip-cli.exe`_) as shown below results in lidar_copy.las that
126is bit-identical to lidar.las. However, the small size of lidar.laz makes it
127much easier to store, copy, transmit, or archive large amounts of LIDAR.
128
129* laszip -i lidar.las -o lidar.laz
130* laszip -i lidar.laz -o lidar_copy.las
131
132LASzip compression can be many times smaller and many times faster than
133generic compressors like `bz2`_, `gzip`_, and `rar`_ because it knows what
134the different bytes in a LAS file represent. Another advantage of LASzip
135is that it allows you to treat compressed LAZ files just like standard LAS
136files. You can load them directly from compressed form into your application
137without needing to decompress them onto disk first. The availability of the
138`LASzip`_ DLL and two APIs, `libLAS`_ and `LASlib`_, with LASzip capability
139makes it easy to add native LAZ support to your own software package.
