A review of AVHRR-based fire susceptibility estimation methods

摘要

The existing methods for fire susceptibility estimation (FSE) based on AVHRR data were applied in different regions of southern Italy. Their performances were evaluated by using a wide data sample of NOAA-12-14 summer imagery acquired from 1996 to 1999. The evaluation was performed by comparing the results obtained from the considered methods and the fire archives provided by the Italian National Forestry Service. The most satisfactory results were obtained from methods based on the cross analyses of NDVI (Normalized Difference Vegetation Index) with satellite-derived thermal data. In particular, the most satisfactory results were obtained when the two indicators are first classified separately and then combined in a single index.
