Purpose of the present study is the geomorphological and land use analysis of the Crete Senesi located in the Asciano municipality (Siena, Italy), by means of both multitemporal series of panchromatic and full chromatic aerial photos, and recent high resolution QuickBird satellite imageries. This work was realized to reconstruct the changes suffered by these famous landscapes with universally conferred naturalistic priceless value. First step of the analysis concerned the orientation of the whole remotely sensed data, for which GCPs were collected by means of DGPS measurements in static mode. A synthetic image starting from the QuickBird satellite imagery has been created by applying an artificial parallax proportional to the digital terrain model. Afterwards the aerial photos have been oriented as well as the satellite imagery by means of digital photogrammetric techniques directed to morphometric study. Digital elevation models related to the different temporal intervals have been calculated from the aerial photos by utilising semi-automatic techniques, whilst the multitemporal land use data base has been carried out through stereoscopic restitution. Map Analysis procedures allowed to compare the data and to rebuild the Crete Senesi’s geomorphologic evolution. Multitemporal land use and elevation data have been utilized as input for the RUSLE in the potential soil loss calculation.
