From a diameter-based to a height-based dendrometry: estimate of tree volume from laser scanning measure ments. Laser scanning is a recently-introduced remote sensing technology that shows high potentiality in the context of the forestry resources management. The research group of the University of Udine, within an IN TERREG IIIA Phare/CBC Italy-Slovenia project, developed specific methods regarding the use of LiDAR data for forestry applications. A specific methodology which makes possible to

On the basis of the height distributions, using stand height curves relation already available in the stand volume tables, a method to derive the volume values of each tree is proposed. The paper shows the first results obtained with the above method in terms of diameter and volume estimation on the basis of laser scanning data surveyed in different composed forestry plots. A comparison between laser-based and traditional methods-based data is also presented. Some of the conse quences of this different way to use the stand volume tables were analyzed, and an experimental procedure is proposed that seems to guarantee a sufficient reliability of the results, and their historical continuity. Fur thermore, the approach described may reduce the costs of the traditional dendrometric assessment, nowa days not sustainable in forest management. Citation: Abramo E, Barilotti A, Sepic F (2007).
