Multi-temporal wet snow mapping in alpine context using polarimetric Radarsat-2 time-series

Lessard-Fontaine, A. ; Allain, S. ; Dedieu, J.-P. ; Durand, Yves

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.
