Vulnerability Zonation Mapping for Landslides' Occurrence Using GIS and Remote Sensing Methodology: A Case Study from Northwestern Greece

This paper presents the creation of a vulnerability zonation map for landslides’ occurrence. This map is developed using Geographic Information Systems (GIS) and remote sensing methods. Seven separate maps are created that include land cover, lithology, distance from road and hydrographic network, altitude, orientation and inclinations of the slopes of the study area, which is the Municipality of Pogoni in Epirus region, northwestern Greece. Then, these maps are calibrated with weighting factors and combined with a linear method. The final map shows three zones of landslides’ hazard occurrence, low, medium and high. The creation of this map may result in credible future location of infrastructure, labeling vulnerability points and settlements and choice of the most appropriate and safer land use in the region.
