The quite new series of photogrammetry software have highlighted how the use of Structure from motion procedures can be well working on archaeological, architectonic, urban and Cultural Heritage subjects. All the main experiences and case studies around are mainly aimed to buildings, urban parts or objects, but being based on photography this kind of software can be applied to almost any subject. The use of photogrammetric digital solutions can be easily exploited to study the sampling of small part of stone out of a complete architecture, creating detailed landscape out of a detail and allowing a specific reading of the content of this small world. The main task can be the one of reading specific alterations, or particular issues in the manufacture of the piece. The main technical troubles are linked to the managing this small parts and editing them to create really usable elements and bringing them in an efficient workflow. In this study the base of the analysis about proce
dures and data treatment will be based on the a set of samples coming from the collaboration between the Departments of Chemical and Geological Sciences from Cagliari and the one of Architecture from Florence on a large group of Romanesque churches in Sardinia; some sampling from the rupestrian churches and settlements in Cappadocia (operated during a research project by the Departments of Architecture in Florence and the Cultural Heritage one from Tuscia), some sampling from major monuments in Florence (operated as personal research). The presentation will be aimed to describe and discuss the shooting solutions, the software procedures and the post processing on data compression and final treatment. This interesting and non invasive method will be analyzed in detailed and all its main features will be described on the base of practical examples.
