“…Furthermore, spectral overlaps between burnt areas and shadows, water bodies and unburnt canopies as well as vegetation regrowth in previously burnt areas can cause difficulties in discriminating between burnt and unburnt areas [5]. Therefore, burnt area mapping algorithms are generally focused on areas with uniform topography and vegetation characteristics [5].…”

“…In particular, the removal of leaves and branches of vegetation due to fire would lead to a change in SAR backscatter [19]. Studies on the use of SAR data for burnt area detection generally rely on the analysis of SAR backscatter at various polarisations and its variation between burnt and unburnt areas [1,2,5] using single-pass [1,5] or multi-temporal analysis [3] approaches. In general, SAR backscatter was found to be affected by many factors including moisture conditions, surface roughness and biomass [4].…”

“…Most of the studies were carried out in boreal forest (Bourgeau-Chavez et al 1997, Kasische et al, 1994, French et al 1999, Siegert and Ruecker, 2000, Menges et al, 2004, but some examples for the Mediterranean area exist San-Miguel-Ayanz, 2004, Gimeno et al 2005). Rather than the changes in vegetation condition and structure, the detection of burnt areas from SAR is based on the changes on moisture content in the burnt surface with respect to the unburned areas.…”
