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 Features for more details on what libLAS can provide a LiDAR software developer. See Getting Started with libLAS 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, this document provides a comparison and description of the relationship of libLAS to LAStools.
