liblas1.8.2 支持LAS/LAZ格式

.. _home: ****************************************************************************** libLAS - LAS 1.0/1.1/1.2 ASPRS LiDAR data translation toolset ****************************************************************************** libLAS is a C/C++ library for reading and writing the very common `LAS` `LiDAR`_ format. The `ASPRS LAS format`_ is a sequential binary file format used to store data from LiDAR sensors and by LiDAR processing software for data interchange and archival. See :ref:`features` for more details on what libLAS can provide a LiDAR software developer. See :ref:`start` for how to get started using the library. libLAS supports the ASPRS LAS format specification versions: 1.0, 1.1, 1.2. libLAS' initial development was supported in 2007-2008 by the `IGSB`_ of the Iowa DNR for use in its state-wide `LIDAR`_ project. Later support for libLAS was provided by a number of organizations including the `U.S. Army Cold Regions Research and Engineering Laboratory`_. As of 2018, libLAS has been replaced by the `PDAL`_ project and it is in hibernation or maintenance mode. libLAS does not provide support for LAS or LAZ 1.4, which PDAL does. PDAL also provides support for many more formats, the notion of `PDAL pipelines`_, Python support, and has packages for OSGeo4W, Docker/Ubuntu/Alpine, and OSX Homebrew. Additionally, libLAS' Python capabilities are much better expressed by the pure-Python laspy http://laspy.org library, and if manipulating LAS data in Python is your ultimate desire, use that instead of libLAS. In short, if you are starting fresh, start with PDAL. .. _`PDAL`: https://pdal.io .. _`PDAL pipelines`: https://www.pdal.io/pipeline.html .. _`U.S. Army Cold Regions Research and Engineering Laboratory` : http://www.crrel.usace.army.mil/ .. _`LASlib`: http://www.cs.unc.edu/~isenburg/lastools/download/laslib.zip .. _`free-as-in-beer`: http://en.wikipedia.org/wiki/Gratis_versus_Libre#.22Free_beer.22_vs_.22free_speech.22_distinction License ------------------------------------------------------------------------------ libLAS is available under the terms of the `BSD License`_.
