Integrating geological, geomorphological and GIS analysis to evaluate the spatial distribution of landslides in the Cino stream catchment (Calabria, south Italy)

Combining field investigation and air-photo interpretation, this work provides a first analysis of the relationships between lithological, structural setting, morphometric features, distribution and characteristics of landslides in the Cino stream catchment (Calabria, south Italy). The morphometric parameters were obtained by digital elevation model (DTM) with pixel size of 10 meters. The DTM has been produced from digitization of contour lines and points of the topographical map of Calabria Region at 1:5000 scale. Data collected were geo-referenced and digitized using a Geographic Information System (GIS), in order to carry out a spatial analysis of landform distributions. For each mapped landform, a database containing attributes of the main features observed has been developed.
