Il presente contributo propone una procedura innovativa per la stima del volume di massa legnosa di soprassuoli forestali mediante elaborazione di dati LiDAR in ambiente GIS, in particolare per i popolamenti a prevalenza di latifoglie dove i convenzionali metodi di stima basati sulle misurazioni LiDAR dell’altezza dei singoli fusti arborei conducono in genere a risultati relativamente insoddisfacenti.

The objective of this paper is to present a new approach for the estimation of growing stock based on ALS data. The approach is distinctively developed for broadleaved stands where conventional methods for growing stock estimation based on ALS measurements of single tree heights frequently provide poor results. Theoretical background and model-based statistical estimators are reported. 2007-12-31T23:00:00Z Area-based assessment of forest standing volume by field measurements and airborne laser scanner data Barbati, Anna Chirici, Gherardo Corona, Piermaria Montaghi, Alessandro Travaglini, Davide http://hdl.handle.net/2067/2137 2011-06-14T00:30:55Z 2008-12-31T23:00:00Z Title: Area-based assessment of forest standing volume by field measurements and airborne laser scanner data Authors: Barbati, Anna; Chirici, Gherardo; Corona, Piermaria; Montaghi, Alessandro; Travaglini, Davide Abstract: Airborne laser scanning (ALS) is increasingly applied as a tool for extracting forest inventory data. In recent years most applications for the assessment of forest standing volume rely on a single tree recognition approach, which generally gives satisfactory results in coniferous forests. The aim of this paper is to apply a rasterbased approach for the assessment of forest standing volume based on field measurements and a Digital Canopy Model (DCM) derived from ALS data. In addition, we explore the potential of hot spot analysis of DCM data for automatic forest gap detection, as a means to improve the accuracy of the estimation of forest standing volume by traditional estimation methods.
