Estimation of forest stem volume in sloping terrain using CARABAS-II VHFSAR data

Sammanfattning

In this paper a heuristic method is presented for reducing topography effects on forest stem volume estimation at stand level using a combination of low-frequency CARABAS-II very high frequency (VHF) synthetic aperture radar (SAR) images acquired from several flight directions. The method has been tested on stand-wise backscatter averages and on segment (derived from digital elevation models) backscatter averages aggregated to stand level. The investigation was performed at two test sites in Sweden characterized by coniferous forests on sloping terrain (ground slope
