Abstract

Vegetation fires play an important role in the emission of aerosols and gaseous compounds contributing to global warming and in various land use practices that can result in land cover changes. Biomass burning is a global phenomenon that affects boreal, tropical and temperate ecosystems. The estimation of the area burnt is a prerequisite for assessing the effects of vegetation fires on the tropospheric chemistry and on the ecosystems. Several algorithms have been developed for mapping burnt areas at regional and continental levels with low spatial resolution images acquired by sensors such as the Advanced Very High Resolution Radiometer (AVHRR), and the Along Track Scanning Radiometer (ATSR) on board orbital satellites.

The SPOT-VEGETATION (VGT) system was showed to be a promising instrument for burnt area detection at regional level. This work presents an improvement of the previous algorithm, based on an image-wide threshold approach, achieved by introducing temporal change detection. .
