TXT-tool 1.039-1.2 Bedding Attitude Information Through the Interpretation of Stereoscopic Aerial Photographs and GIS Modeling Ivan Marchesini, Michele Santangelo, Federica Fiorucci, Mauro Cardinali, Mauro Rossi, Francesco Bucci and Fausto Guzzetti Abstract Information on bedding attitude is necessary to define the geological and structural setting of an area and is relevant for the assessment of landslide susceptibility at different scales and in different physiographic environ- ments. Bedding planes are a known factor controlling the type, abundance, and pattern of landslides. Where layered rocks crop out, the geometrical relationships between the attitude of the bedding and the geometry of the terrain is crucial to understand landslide phenomena. Obtaining information on bedding attitude for large areas through field surveys is time consuming, and resource intensive, hampering the possibility of quantitative investiga- tions on the control of bedding planes on landslides. We describe a GIS-based method to extract information on bedding planes from the analysis of information captured through the visual interpretation of stereoscopic aerial photographs and a digital representation of the terrain. Results show that our procedure provides bedding attitude information in good agreement with bedding attitude data acquired during field surveys.
