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. 84 85 86 87Binaries 88.............................................................................. 89 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. 98 99 100Documentation 101.............................................................................. 102 103 - The LASzip `paper`_ and `video`_ from the ELMF 2011 presentation in Salzburg, Austria. An `interview <http://geodatapoint.com/articles/view/expanding_access_to_lidar_through_compression>`_ with editor Christine Grahl of POB magazine. 104 105 106Development Source 107------------------------------------------------------------------------------ 108 109* Current Trunk: https://github.com/LASzip/LASzip 110 111 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. 140 141Software with native LAZ support 142------------------------------------------------------------------------------ 143 144* Fugroviewer (2.0 and up) by `Fugro <http://www.fugroviewer.com/>`_ 145* QT Modeler (7.1.6 and up) by `Applied Imagery <http://www.appliedimagery.com/>`_ 146* ERDAS IMAGINE (14.1 and up) by `Hexagon Geospatial <http://www.hexagongeospatial.com/products/ERDAS-IMAGINE/Details.aspx>`_ 147* Global Mapper (13.1 and up) by `Blue Marble Geo <http://www.bluemarblegeo.com/>`_ 148* Trimble RealWorks (8.1 and up) by `Trimble Navigation Limited <http://www.trimble.com/3d-laser-scanning/realworks.aspx>`_ 149* ENVI LiDAR (5.1 and up) by `Exelis VIS <http://www.exelisvis.com/ProductsServices/ENVI/ENVILiDAR.aspx>`_ 150* FME (2012 and up) by `Safe Software <http://www.safe.com/>`_ 151* TopoDOT by `Certainty3D <http://www.certainty3d.com/products/topodot/>`_ 152* Pointools by `Bentley Systems <http://www.pointools.com/>`_ 153* Pix4uav by `Pix4D <http://www.pix4d.com/>`_ 154* CloudCompare by `Daniel Girardeau-Montaut <http://www.danielgm.net/cc/>`_ 155* SURE by `nframes <http://www.nframes.com/>`_ 156* Pointfuse by `Arithmetica <http://pointfuse.com/>`_ 157* LAStools by `rapidlasso - fast tools to catch reality <http://rapidlasso.com/>`_ 158* plas.io 3D Web Viewer by `Hobu Inc. <http://plas.io/>`_ 159* RiProcess by `RIEGL LMS GmbH <http://www.riegl.com/>`_ 160* CloudPro by `Leica Geosystems AG <http://www.leica-geosystems.com/en/About-us-News_360.htm?id=5380>`_ 161* Optech LMS (3.0 and up) by `Teledyne Optech <http://www.teledyneoptech.com/index.php/product/optech-lms/>`_ 162* Leica LIDAR Survey Studio LSS (2.2 and up) by `Leica Geosystems AG <http://www.leica-geosystems.com/en/About-us-News_360.htm?id=5960>`_ 163* FUSION (3.40 and up) by `Bob McGaughey of the USDA <http://forsys.cfr.washington.edu/fusion/fusionlatest.html/>`_ 164* ZEB1 by `3D Laser Mapping <http://www.3dlasermapping.com/index.php/products/handheld-mapping>`_ 165* OCAD (11.4.0 and up) by `OCAD Inc. <http://ocad.com/blog/2013/11/ocad-11-4-0-supports-laz-files/>`_ 166* Gexcel R3 by `Gexcel <http://www.gexcel.it/en/software/>`_ 167* Voyager (1.3 and up) by `Voyager GIS <http://www.voyagergis.com/>`_ 168* LIDAR Analyst (5.2 or 6.0 and up) by `TEXTRON Systems <http://www.textronsystems.com/>`_ 169* TerraScan, TerraMatch, TerraPhoto, and TerraSlave (015.xxx and up) by `Terrasolid <http://www.terrasolid.com/>`_ 170* Carlson (2016 and up) by `Carlson Software <http://carlsonsw.com/>`_ 171* Remote Sensing Software by `Joanneum Research Forschungsgesellschaft mbH <http://www.remotesensing.at/en/remote-sensing-software.html>`_ 172* LiMON Viewer by `Dephos Software <http://www.limon.eu/products/compare-versions/>`_ 173* Scanopy by `imagination <http://www.imagination.at/>`_ 174* WinGeoTransform by `KLT Assoc <http://www.kltassoc.com/>`_ 175* BayesStripAlign by `BayesMap Solutions, LLC <http://bayesmap.com/>`_ 176* Point Cloud Technology by `Point Cloud Technology, GmbH <http://www.pointcloudtechnology.com/>`_ 177* Scalypso by `Ingenieurbuero Dr.-Ing.
