Mistra Digital Forest invites you to an one hour-webinar showcasing recent developments in digital forestry on Tuesday 21 April, 2026 at 10:00.
The session features two presentations: one on tree maps derived from airborne laser scanning, and one on the Computational Forestry Lab and the role of high-performance computing in forestry research.
Tree maps from airborne laser scanning
Johan Holmgen, SLU
The Mistra Digital Forest (MDF) Test Site North covers approximately 125,000 hectares of forest land. The area has been scanned using high-resolution airborne laser scanning, enabling the extraction of tree-level information through large-scale tree segmentation. Using the Computational Forestry Lab (CFL), tree maps are produced for the entire area. These products from the Test Site North will also be made accessible for use within the research program.
A key challenge is obtaining suitable training data for models used to predict stem attributes for the tree maps. One approach is to use standard production files from harvesters as training data. In parallel, algorithms are being developed to estimate tree stem size and shape using laser scanners mounted directly on harvesting machines.
Computational Forestry Lab and high-performance computing for forestry
Lucas Hedström, Umeå University
The Computational Forestry Lab (CFL) is a high-performance supercomputer integrated within the High-Performance Computing Center North (HPC2N) at Umeå University. CFL is specifically designed to support forestry- and AI-related research and applications.
This part of the webinar provides an overview of CFL and its resources, highlights ongoing projects that utilize the platform, and outlines future plans for high-performance computing within forestry research.
