Abstrakti

Determination of aboveground biomass (AGB) requires accurate measurements from individual trees including measurements of height, multiple stem diameters, density of the wood, bark and branches, and dry mass of the needless. These measurements are time-consuming and expensive, and can only be collected in a destructive manner. Terrestrial and airborne laser scanning (TLS / ALS) are promising techniques for measuring the required tree attributes that can be used in the estimation of AGB of the single trees. TLS and ALS produce dense three-dimensional (3D) point clouds that can be used in extraction of various tree attributes. The main objective was to develop and evaluate the accuracy of a combination of ALS and TLS in total AGB modelling. The study also reviews state-of-the-art in laser scanning-based single tree AGB modelling. The use of ALS in the estimation of canopy biomass have been promising, but can be further improved with TLS data. Thus, in the further studies TLS and ALS should be combined to improve the single tree AGB modelling accuracy.
