). Moreover, threshold values are not constant and sometimes require to be tuned for the different environments or even adapted to local conditions or from scene to scene ( Barbosa et al. 1999 ; Smith et al. 2007 ). The objective of our research was to develop a new algorithm for mapping fire-affected areas in a Mediterranean environment from postfire HR satellite images. The algorithm integrates multiple SIs to exploit the complementary and/or the redundant information brought by each of them and to

conditions or differences in fire behavior ( Giglio et al. 2006b ). These issues can be solved through the combination of collecting active fire information together with spectral indices. Following this model, Roy et al. ( Roy et al. 1999 ) developed a multitemporal burn scar detection algorithm that used a time series of burn scar index data (based on a vegetation index) derived from Advanced Very High Resolution Radiometer (AVHRR) daily images to compute a burn scar index change map that was then
