Road infrastructure projects have proven to be a challenging task, particularly in a dynamic setting, such as mountains and hillsides. Such an endeavour entails the integration and processing of cross-disciplinary research, particularly engineering and geosciences. Our study is oriented towards the geographic aspects, specifically the ones involving applied geomorphology. We aim to provide a cartographic solution that reveals the areas suitable for developing a road network, based on a geomorphologic and environmental approach. This is achieved through a GIS-based multi-criteria analysis involving raster data sets of different geodynamic factors, such as geology, pedology, gravitational processes, land use and other environmental components.
