“…This made it possible to analyze geographic information, apply particular algorithms, perform statistical analyses and model the results. Several researchers have underlined the importance of this approach for mapping the hazard associated with landslides (Brabb, 1984 and1987;Wadge , 1988;Van v , 1993;Brabb , 1995;Carrara et al, 1995;Irigaray , 1995;Soeters and Van Westen, 1996;El Kharim , 2002). Furthermore, some researchers have highlighted the interest of combining satellite imagery with GIS to establish maps of the hazard linked to landslides Leroi et al, 1992;Van Westen , 1993).…”
