Burn Scar Map by High Resolution Optical Data


The most effective, passive remote-sensing methods for detecting and mapping BSs on high resolution data (meters to tens of meters), rely upon the observation in near-infrared (NIR) and short-wavelength infrared (SWIR) bands, either in contextual (single-image) or in multi-temporal mode. In the multi-temporal case, a method to separate reflectance variation due to vegetation damage from changes due to other factors influencing the at-satellite reflectance, is that of identifying pseudo-invariant features (Permanent Reflectors o PR) to be used as reference targets in different scenes.
This approach is integrated in a three-step, multi-patented procedure called MYME2 (PCT/IT04/000376, WO2005/005926A1, EP/1642087). It includes: (i) selection of pixels presenting a decrease in biomass content and chlorophyll absorption (compared to PRs variation) from image N-1 and the image N, (ii)  Selection of non-vegetated pixels located in the image N, (iii) Pixels selected in the previous steps are considered to have undergone fire damage. MYME2 is a multi-temporal method, robust, fast, automated, unsupervised, and independent of the payload, allowing for detection of fire damaged areas higher than one hectare.
It is recommended a monthly update of the BS map for two principal reasons (i) avoid the removal of ash or charcoal - that remain the univocal indicators of fire damage, and (ii) assess the damage before the re growth of vegetation cover.
