We proudly present


Tool for point cloud data processing from forest environment acquired by terrestrial laser scanner.

Our story

Looking for software tool to analyse your TLS data? You just find one! We are glad to present you open-source software application for lidar data segmentation, visualization, measurement and export of various tree parameters. Let’s start with image gallery and enjoy insight into old-growth forest where this application serve for studying forest structure and dynamic in 3D space. Feel free to download and test it from download page and leave comment or sugestion at our forum. We are using also ticket system for improvements and bug report.

The 3D Forest Project started in year 2010 at Department of Forest Ecology of The Silva Tarouca Research Institute. In cooperation with Department of Geoinformation Technologies of Mendel University in Brno. Increasing need for analyzing real three-dimensional data from forest environment was apparent and widely acknowledged across numerous research questions in forestry and forest ecology. After extensive search for the best possible approach for acquiring and processing 3D data we found terrestrial laser scanning as the best data for our needs. The only missing piece was the powerful but user friendly processing tool, so we decided to create one by ourself – the 3D Forest.


Martin is going to present the latest version of 3D Forest at SilviLaser 2019 conference in Brazil, Iguazu Falls – October 8-10. See you there!

Recreating the 3D Forest web to be more vivid and attractive. We added section ‘News’ for reporting about our work progress, team and important events.
