Geomatics application for geological and geomorphological mapping and landslide hazard evaluation: case studies in the Italian NW-Alps
نویسندگان
چکیده
Theoretical assumptions, research methodologies and results applications of innovative geological and geomorphological mapping for landslide hazard evaluation in the alpine environment are presented in the paper. Case studies from the Italian NW-Alps highlight the role of Geomatics techniques in enhancing the accuracy of multitemporal reconstructions of geomorphic processes and landforms. Aerial and satellite remote sensing stereoscopy, derived DTMs, high resolution hyperspectral images, allow precise slope movements evaluation and detailed thematic mapping. Results are available for supporting hazard studies and disaster management.
