This paper describes an approach to develop a time-series slope hazard map using multi resolution satellite images. This approach initially gives tree root status using relationships between spectral radiances and vegetation parameters such as leaf area index (tree crown), vegetation types (vegetation species), vegetation density and the arrangement. Then the slope hazard (slope stability) is calculated by using parameters derived from laboratory tests. Finally forest hazard map can be generated. Therefore the map can be updated when satellite data are acquired.
