Post-fire Vegetation Recovery Map


The method applied to define the effective vegetation re-growth and/or biomass increase, is based on the same technical and scientific approach used for Burn Scar Map from high resolution optical data. Taking the Permanent Reflectors (PRs) as the internal references (PCT/IT04/000376, WO2005/005926A1, EP/1642087), all pixels presenting a reflectance increase in Vis-NIR channels and an increase of the ratio between NIR and SWIR channels from acquired multi-spectral image N-1 to image N, are considered to have undergone post-fire vegetation recovery.
