A free LiDAR toolbox software is available from ArcLand. The Lidar Visualisation Toolbox LiVT written by Ralf Hesse at the State Office for Cultural Heritage Baden-Württemberg has now been published as an open source software project under the GNU General Public License (GPL). LiVT is a software for the computation of a variety of visualisations from high-resolution DEM data. Starting with the current version LiVT 184.108.40.206, Windows binaries, source code and documentation are now available for download at https://sourceforge.net/projects/livt/. The main change from version 220.127.116.11 to 18.104.22.168 is the addition of MultiScaleIntegral Invariants (MSII).
