We proudly present


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


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.

Our story

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.



new version 0.52 with incorporated methods for charcoal sites analysis is right now out for your point cloud data workflow. youcan download new version from Download section of on this link: https://github.com/VUKOZ-OEL/3DForest/releases/download/v052/3DForest_052.exe


3D Forest v. 0.51 has been released! Version 0.51 brings new tools for terrain analysis and classification of terrain features directly from the terrain pointcloud. It also brings new descriptions of existing tools, more intuitive dialog windows and much more… Enjoy it!


We are happy to announce that we just published a new paper about processing utra-high-density drone lidar data for area-wide mapping of individual trees using 3D Forest. The paper received publicity also on ForestGEO’s Twitter and Facebook pages.


We have updated the Wiki User’s Guide. We believe that the new user manual better describes the functionality of 3D Forest and will be useful for all and especially for new users of the 3D Forest. At the same time we are working on updates of some 3D Forest dialog windows to be more intuitive. It will be part of the 0.51 release. Comming soon!


The article introducing 3D Forest (Trochta et al. 2017) is among the top 10% most cited PLOS ONE papers published in 2017! Thank you for your interest!!

Why choose us?

Our application is free for all users. Thanks to licence GPL v3 we can publish our work with garanty that user will never pay for this piece of code.

During our mission we have collected a big amount of data from forest environment. Our datasets has area at least 1 ha on more than 5 plots. If you are intersted in cooperation feel free to contact us.
