With TLS data you can analyze whole forest site.
Automated method for basic tree parameters can be fast and precise.
Analyze how tree affecting it neighborhood.
Extraction of terrain with automated methods.
Whole application is free for all users.
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.
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.
Are you interested in 3D approach in forest ecology and want to know more about what the 3D Forest team is working on? ForestGEO just posted the blog on their website, with a short interview with Kamil. Announced also on ForestGEO Facebook and Twitter pages.
The ability of 3DForest to assess three-dimensional tree/crown asymetry and crown shape plasticity will be presented in Helsinki, Finland on the workshop “3D Tree Models for Forest Dynamics” (https://forestdynamics.fi/3dfdyn/), January 9th and 10th 2020. See you there!
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!!
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.
