The experimental study results demonstrate the possibilities for quantitative assessment of forest burnt severity using
various vegetation indexes derived from satellite remote sensing measurements of spectral reflectance in visible,
near- and mid-infrared spectral ranges. These vegetation indexes have been retrieved applying both satellite data
acquisition strategy, namely using post-fire image only and also based on bi-temporal pre- and post-fire images.
Ground-truth reference data on burnt severity have been collected on test sites located in Chita Oblast, Krasnoyarsk
Kray and Republic of Buryatia and were used as independent source of information on forest status. The highest
performances in terms of correlation with reference data on forest burnt severity have demonstrated vegetation indexes
estimated using bi-temporal pre- and post-fire images in near- and mid-infrared spectral bands.
