ABSTRACT: The aim of this work concerns the development of a simple and rigorous procedure for the construction of metric orthophotos in high geometric resolution and rich in detail through the use of terrestrial and UAV photogrammetry techniques. This approach has been tested on various datasets relating to the Racconigi Castle (Italy) and has allowed the state of the sites to be documented. All the orthophotos produced made it possible to identify the critical areas from a conservation point of view and, at the same time, to create a support tool that makes it possible to identify, with high precision, the damaged areas in a short time thanks to the georeferencing of the processed models.
