Abstract :
The temporal monitoring of snow cover in mountainous areas is a very important challenge in order to predict snow melting. A way to solve this problematic is the snow detection using polarimetric SAR data. By this way, a set of eight Radarsat-2 images have been acquired over the French Alps during 2009 and 2010. This project proposes to apply snow detection algorithms with some improvements to map dry/no snow cover over the study area under different snow conditions.
