******************************************************************************
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 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' initial development was supported in 2007-2008 by the `IGSB`_ of the
Iowa DNR for use in its state-wide `LIDAR`_ project. Ongoing support for
libLAS is provided by a number of organizations including the
`U.S. Army Cold Regions Research and Engineering Laboratory`_.
libLAS builds upon by `Martin Isenburg and Jonathan Shewchuk`_ of LLNL/UC
Berkeley in their `LAStools`_ project to do a number of things. First, the
libLAS focuses almost completely on providing an easy-to-program-with library
for software developers wishing to implement the LAS specification in their
own software. libLAS is a building block for developers looking to implement
their own LiDAR data processing when working with ASPRS LAS data.
For more information, :ref:`this document <lastools_liblas>` provides a
comparison and description of the relationship of libLAS to LAStools.
