The paper describes a multidisciplinary and integrated methodology related to material and structural elements tests, Laser Scanner surveys and Remote Sensing technology, applied to Historical Heritage. The knowledge process was aimed at defining the rehabilitation project of an historic building in Caporciano, a small old town centre damaged by the Abruzzo (Italy) earthquake which occurred on April 6th, 2009. The building analyzed is characterized by an extremely complex morphology, developed on different levels and making surveys using traditional methods particularly difficult. Therefore the laser scanning technique, which provides a complete 3D model of the entire structure, has been used. Due to the effects of the earthquake, the testing of the building’s structure had to take several aspects into consideration. An extensive non-destructive and semi-destructive tests survey has been performed, in order to obtain historical-architectural knowledge and in situ materials characterization. The main techniques used were thermograph, ground penetrating radar, endoscopy, masonry analysis and mortar penetration test. In this case study, UAV remote sensing was employed, to collect data thanks to sensors mounted on carriers operating at low altitude. I was able to survey the roofs of the buildings: captured images were processed to identify any damage even on inaccessible areas.
