Abstract. The contribution addresses the issue of the integrated survey aimed at three-dimensional modeling for the documentation of different types of terrain through the analysis of two case studies located in the province of Pavia - Italy. The techniques of aerial photogrammetric acquisition SfM (UAVs), Terrestrial Laser Scanner (TLS) and Mobile (MLS) are now consolidated and widely used, managing to meet the needs of documentation of land levelling, monitoring, and analysis of landslide volumes. The two case studies present difficulties due to a strong inclination of the land and extensive presence of vegetation in the first case and to a strong presence of agricultural canalizations in the second case. The data processing phase focused on the comparison between MLS and close-range photogrammetry, while the acquisitions from TLS were used as control data. This acquisition method allows avoiding the process of approximation and reconstruction of the DTM under the vegetation, ensuring the correctness of the data relating to the ground course. The database allows the generation of highly reliable DTMs using specific point cloud modeling and processing software. Fast survey instruments are ideal in large areas or in hilly areas where sub-vertical sections and covered by vegetation are often present, difficult to detect only with close-range photogrammetry.

The survey project of the Amerigo Vespucci is part of a research line that DiDA, Department of Architecture of the University of Florence, developed through an experience of collaboration and partnership with the Department of Defense. For more than two years, the Department has been involved in the study of the Cascine park, in Florence, analyzing the architectures of historical value, with a particular focus on the Scuola di Guerra Aerea. The documentation of the architectural heritage received in recent years an innovative technological boost, which led to the development of new modern methodologies of investigation. It is possible to apply integrated survey methods not only to immovable assets such as historical buildings, which abounds in our country, but also to movable ones, included vessels. By now, the processes of data registration and graphical restitution of the survey, both laser-scanner and photogrammetric, are functioning and consolidated, and can therefore be applied in research projects, if the appropriate considerations on the specific asset typology of the subject of study are taken. The application of specific instruments in support of the survey and architectonic representation enables us to achieve increasingly accurate results, engaging multiple aspects of the structure under study. The project investigating the Nave Scuola Amerigo Vespucci allows to expand the current knowledge on the sailboat in order to provide, through survey methods and architectonic representation, the documentation necessary to conduct future renovations and wood restorations. The aim of the present research is to create a digital database that, similarly to those used for buildings of historical value, would facilitate the management of this excellent asset of the Italian Navy.
