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

Περίληψη

This paper presents the creation of a landslide vulnerability map. The latter is developed using Geographic Information Systems (GIS) and Remote Sensing methods. Seven separate maps that include land cover, lithology, distance from road and hydrographic network, altitude, orientation and slope gradient in the study area, which is the Municipality of Pogoni in the region of Epirus, northwestern Greece, are created. Then, these maps are calibrated with weighting factors and combined with a linear method. In the final map, three landslide vulnerability zones, low, medium and high, are represented. The creation of this map may result in credible future location of infrastructure, identification of vulnerable spots and settlements and selection of the most appropriate and safer land use in the region.
