Terrestrial laser scanning (TLS) is providing exciting new ways to quantify tree and forest
structure, particularly above-ground biomass (AGB). We show how TLS can address some of …

… The restriction dis P of the distance dis to P M gives the distances between the points of P M
, and thus also a metric topology for P M . Notice that dis P locally approximates the distance …

… The QSMs in this paper are reconstructed with a modified version of the method presented
in Raumonen et al. (2013). The original method was validated previously using detailed 3D …

… P s u b is subdivided into P S t e m and P B r a n c h . P S t e m ( P B r a n c h is processed
in … Clustering ( e p s C l u s t e r S t e m , 5 , m i n P t s C l u s t e r S t e m ) into i clusters …

… We reconstructed the woody structure of trees using the QSM method developed by
Raumonen et al. (2013) and further developed by Calders, Newnham, et al. (2015) and …

… To determine the r-ball for the point p, we take the r-cube of p and its 26 neighbouring cubes
to restrict the search to nearby points. More details can be found in Raumonen et al. 2013. …

Calibration and validation of aboveground biomass (AGB) (AGB) products retrieved from
satellite-borne sensors require accurate AGB estimates across hectare scales (1 to 100 ha). …

Above-Ground Biomass (AGB) product calibration and validation require ground reference
plots at hectometric scales to match space-borne missions' resolution. Traditional forest …

Key message A method using terrestrial laser scanning and 3D quantitative structure models
opens up new possibilities to reconstruct tree architecture from tropical rainforest trees. …

… Pasi Raumonen … This approach builds on Raumonen et al. [13] and fits cylinders to the point
cloud … Lewis, P. Three-dimensional plant modelling for remote sensing simulation studies …
