    <description>Title: Applications of very high resolution satellite imagery to forest ecosystem assessment
Authors: Chirici, Gherardo; Barbati, Anna; Bottalico, Francesca; Corona, Piermaria
Abstract: The latest generation of commercial satellite sensors&#xD;
provides image products with very high geometric resolution (VHR).&#xD;
VHR images have been extensively exploited in the last years for&#xD;
monitoring forest ecosystem conditions. This chapter presents a&#xD;
review of applications in several fields: forest assessment, forest&#xD;
mapping, detection of stand structural attributes, forest disturbances,&#xD;
estimation of forest biomass and other biophysical variables. Current&#xD;
scientific knowledge under each issue is discussed and most&#xD;
promising classification techniques and approaches are outlined

Abstract: In questo studio è stata valutata la potenzialità del telerilevamento laser scanner aereo (ALS) per&#xD;
classificare le forme di governo forestale in un bosco misto di latifoglie. La metodologia applicata&#xD;
prevede l’utilizzo del modello digitale delle chiome (CHM) ottenuto da dati ALS e l’impiego di&#xD;
procedure automatizzate per la segmentazione object-oriented delle immagini telerilevate. La&#xD;
classificazione delle forme di governo si basa sulle metriche estratte dal CHM. I risultati ottenuti&#xD;
indicano che la media delle altezze e il coefficiente di variazione delle altezze estratti dal CHM&#xD;
sono utili per distinguere i boschi governati a ceduo da quelli governati a fustaia; In this study aerial laser scanning (ALS) data has been tested to classify coppice stands and high&#xD;
forest stands in a mixed broadleaved forest. The method is based on a canopy height model (CHM)&#xD;
obtained from ALS data. Forest stands have been delineated using a object-oriented approach. The&#xD;
polygons have been classified into coppices and high forests based on the metrics derived from&#xD;
CHM. Our results indicate that the mean of the heights and the coefficient of variation of the&#xD;
heights extracted from CHM are useful to discriminate coppices from high forests.
