    • Analysing individual 3D tree structure using the R package ITSMe 

      Terryn, Louise; Calders, Kim; Åkerblom, Markku; Bartholomeus, Harm; Disney, Mathias; Levick, Shaun; Origo, Niall; Raumonen, Pasi; Verbeeck, Hans (01 / 2023)
      article
      Detailed 3D quantification of tree structure plays a crucial role in understanding tree- and plot-level biophysical processes. Light detection and ranging (LiDAR) has led to a revolution in tree structural measurements and ...
    • Automatic tree species recognition with quantitative structure models 

      Åkerblom, Markku; Raumonen, Pasi; Mäkipää, Raisa; Kaasalainen, Mikko (15.03.2017)
      article
      We present three robust methods to accurately and automatically recognize tree species from terrestrial laser scanner data. The recognition is based on the use of quantitative structure tree models, which are hierarchical ...
    • Bayes Forest : A data-intensive generator of morphological tree clones 

      Potapov, Ilya; Järvenpää, Marko; Åkerblom, Markku; Raumonen, Pasi; Kaasalainen, Mikko (2017)
      article
      Detailed and realistic tree form generators have numerous applications in ecology and forestry. For example, the varying morphology of trees contributes differently to formation of landscapes, natural habitats of species, ...
    • Non-intersecting leaf insertion algorithm for tree structure models 

      Åkerblom, Markku; Raumonen, Pasi; Casella, Eric; Disney, Mathias I.; Danson, F. Mark; Gaulton, Rachel; Schofield, Lucy A.; Kaasalainen, Mikko (06.04.2018)
      article
      We present an algorithm and an implementation to insert broadleaves or needleleaves into a quantitative structure model according to an arbitrary distribution, and a data structure to store the required information ...
    • Realistic forest stand reconstruction from terrestrial LiDAR for radiative transfer modelling 

      Calders, Kim; Origo, Niall; Burt, Andrew; Disney, Mathias; Nightingale, Joanne; Raumonen, Pasi; Åkerblom, Markku; Malhi, Yadvinder; Lewis, Philip (01.06.2018)
      article
      Forest biophysical variables derived from remote sensing observations are vital for climate research. The combination of structurally and radiometrically accurate 3D "virtual" forests with radiative transfer (RT) models ...
    • Simulating solar-induced chlorophyll fluorescence in a boreal forest stand reconstructed from terrestrial laser scanning measurements 

      Liu, Weiwei; Atherton, Jon; Mõttus, Matti; Gastellu-Etchegorry, Jean Philippe; Malenovský, Zbyněk; Raumonen, Pasi; Åkerblom, Markku; Mäkipää, Raisa; Porcar-Castell, Albert (2019)
      article
      Solar-induced chlorophyll fluorescence (SIF) has been shown to be a suitable remote sensing proxy of photosynthesis at multiple scales. However, the relationship between fluorescence and photosynthesis observed at the leaf ...
    • Terrestrial laser scanning : A new standard of forest measuring and modelling? 

      Åkerblom, Markku; Kaitaniemi, Pekka (2021)
      review
      Background: Laser scanning technology has opened new horizons for the research of forest dynamics, because it provides a largely automated and non-destructive method to rapidly capture the structure of individual trees and ...
    • Tree species classification using structural features derived from terrestrial laser scanning 

      Terryn, Louise; Calders, Kim; Disney, Mathias; Origo, Niall; Malhi, Yadvinder; Newnham, Glenn; Raumonen, Pasi; Åkerblom, Markku; Verbeeck, Hans (01.10.2020)
      article
      Fast and automated collection of forest data, such as species composition information, is required to support climate mitigation actions. Recently, there have been significant advances in the use of terrestrial laser ...
    • Uncertainty in multispectral lidar signals caused by incidence angle effects 

      Kaasalainen, Sanna; Åkerblom, Markku; Nevalainen, Olli; Hakala, Teemu; Kaasalainen, Mikko (06.04.2018)
      article
      Multispectral terrestrial laser scanning (TLS) is an emerging technology. Several manufacturers already offer commercial dual or three wavelength airborne laser scanners, while multispectral TLS is still carried out mainly ...
