Very light UAV data and ranging methods for heritage documentation. The teaching activities of a master’s degree course

Even more the 3D documentation of the Built Heritage is requested for several metric purposes and digitization objectives. In the last years according to the evolution of the recording and processing techniques producing a 3D model become quite straightforward and is important to understand how the process could be managed and controlled. With this aim, starting from 2008 in the architecture master’s course of the Politecnico di Torino a Geomatics workshop is offered to the students. The paper deal with the experience carried out during the a.y. 2018-2019 with the aim of integrating data acquired by a very light UAV and different range-based sensors for documenting an historical and stratified fortified architecture. The problems related with the flight authorization and the followed strategies for data acquisition using the UAV and the employed range-based sensors are discussed. In conclusion the achieved metric products and the analyses are reported.
