Landslide Susceptibility Mapping Using Gis-Based Weight-of- Evidence Modelling in Central Georgian Regions

This paper explains the procedure for the generation of a landslide susceptibility map at regional level in Georgia. At the first place, this research presents the results of the weight-of-evidence model applied to estimate the probability of landslides manifestation. A spatial database, including causative factors associated with landslides was constructed from geological maps and satellite data products. The factors that influence landslide occurrence, such as terrain slope, aspect, curvature, elevation, flow accumulation and distance from drainages were calculated from a Sentinel-1 digital terrain elevation data (DTED). Lithology is derived from the Georgia’s geological map. Vegetation cover map is retrieved from Sentinel-2 multispectral satellite imagery
