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 22.214.171.124, Windows binaries, source code and documentation are now available for download at https://sourceforge.net/projects/livt/. The main change from version 126.96.36.199 to 188.8.131.52 is the addition of MultiScaleIntegral Invariants (MSII).
