“…Obviously, the surveys on the S. Agostino church do not correspond to the only reference of what has been done, and many other examples can be found in literature (Gagliolo et al 2017). However, this case study well represents which results could be obtained by adopting such photogrammetric toolsboth the terrestrial and the aerial ones -, as well as which their critical points and their future developments could be.…”

Abstract. Concerning the care of our Built Heritage, one of the most important problem that was observed after an earthquake is the speed in the reaction, aiming to minimize the damages provoked by the shakes. As a matter of fact, the necessary time for the reaction of the rescue teams should be not too long, in order to avoid further damages provoked by the future shakes. Thus, the best way to minimize this type of damage is to design appropriate shoring systems that replace the lack of stiffness provoked by earthquake as soon as possible. In this sense, it’s necessary to know many information of a damaged monument, such as: the geometry, the materials and the structural characteristics, the presence of previous alterations and/or restorations, etc. Unfortunately, the accessibility to this kind of information is not always available after an earthquake, due to the possible damages provoked to the buildings, where the public archives and the documentation are normally stored (L’Aquila 2009, Amatrice 2016).The awareness of this problem started immediately after the serious earthquake that hit the city of L’Aquila in 2009. Then, it became more urgent after 2016, when the extended and continued earthquake in the Centre of Italy provoked increasing damages to buildings and monuments. In particular, an important role in the churches’ collapses that had occurred during this last earthquake was due to the difficulty in finding the necessary information to design proper shoring systems.Nowadays, starting from the experience of L’Aquila, teams composed by functionaries of the Ministry of Culture, engineers from different universities and special members of the Fire Brigade have developed and improved various models for the management of the emergency phases. Using the modern geomatics tools (i.e. Unmanned Aerial Systems (UAS), Terrestrial Laser Scanners (TLS), Remotely Piloted Aircraft Systems (RPAS)), it’s possible to achieve the digital acquisition of many building’s data and characteristics (i.e. through the 3D Object recognition and reconstruction, the point cloud analysis, etc.).This article examines some of the most interesting solutions that were adopted after the recent Italian earthquakes (L’Aquila 2009, Emilia-Lombardia 2012, Centre of Italy 2016) by some of the major public Entities (Superintendences, Italian Fire Brigade). Moreover, it evaluates the possibility to enhance both the competences and the tools that have been until now developed, with the purpose to use them for an effective Built Heritage prevention, without having to wait a new emergency phase to adopt them.

“…Dominici et al (2016) believe that UAV photogrammetry is an excellent data acquisition platform for metric surveys of damage in areas inaccessible or unsafe for human beings. Gagliolo et al (2017) explain that UAV photogrammetry allows to obtain good results in terms of speed, economy, precision and accuracy, while ensuring the safety of operators in critical situations. They have also discussed a case study carried out in Italy.…”

In the last decades, the UAV photogrammetry has been widely employed to obtain a complete and metric survey in different fields, especially when high resolution, speed of execution and safety are required. It is widely used in the construction sector and an interesting research field is their use to support the historical centres urban renewal projects, especially in post-earthquake reconstruction. In fact, the establishment of a construction site involves several intrinsic criticalities linked to the nature of the context, and especially in a post-earthquake scenario, additional problems arise beyond these critical elements. These conditions affect the preservation of historical centres, planned conservation, risk and resilience management. For this reason, it is necessary to develop innovative methodologies and strategy to plan interventions and to manage the construction sites in the historical centre after an earthquake. The use of UAV photogrammetry is a tool to support this activity in this field because it allows obtaining a complete and a highresolution geometric survey of the areas to be reconstructed in a fast way and especially in total safety for the operators. For this reason, this study aims to illustrate a methodology that, starting from a series of preliminary surveys, supports the development of the program of reconstruction of a historic urban centre hit by an earthquake event. The aim of this research is to prevent problems, interferences and criticalities in order to increase the safety and rationality of the entire reconstruction process.

“…Therefore, it is difficult to define standard procedures and the integration of different technologies seems often the best solution. Integration of several 3D data acquisition techniques is becoming an important resource in Cultural Heritage surveying of valuable historical monuments and it provides complete and multi-scale information according to the monument complexity, the accessibility of the area and the different level of detail required (Gagliolo et al, 2017). New strategies and new techniques coming from photogrammetry are becoming standard approaches in Cultural Heritage survey.…”

The photogrammetric survey of architectural Cultural Heritage is a very useful and standard process in order to obtain accurate 3D data for the documentation and visualization of historical buildings. In particular, the integration of terrestrial close-range photogrammetry and Remotely Piloted Aircraft Systems (RPASs) photogrammetry allows to create accurate and reliable 3D models of buildings and to monitor their state of conservation. The use of RPASs has indeed become more popular in Cultural Heritage survey to measure and detect areas that cannot normally be covered using terrestrial photogrammetry or terrestrial laser scanner. The paper presents the results of a photogrammetric survey executed to document the monumental complex of Villa Lampedusa ai Colli in Palermo (Italy), one of the most important historical buildings of the town. An integrated survey by close-range photogrammetry and RPAS photogrammetry was planned and carried out to reconstruct the 3D digital model of the monumental complex. Different images configurations (terrestrial, aerial nadiral, aerial parallel and oblique to the façades) have been acquired; data have been processed to verify the accuracy of the photogrammetric survey as regards the camera calibration parameters and the number of Ground Control Points (GCPs) measured on building façades. A very detailed 3D digital model and high-resolution ortho-images of the façades were obtained in order to carry out further analysis for historical studies, conservation and restoration project. The final 3D model of Villa Lampedusa ai Colli has been compared with a laser scanner 3D model to evaluate the quality of the photogrammetric approach. Beyond a purely metric assessment, 3D textured model has employed to generate 2D representations, useful for documentation purpose and to highlight the most significant damaged areas. 3D digital models and 2D representations can effectively contribute to monitor the state of conservation of historical buildings and become a very useful support for preliminary restoration works.
