Integrated technologies for indirect documentation, conservation and engagement of the Roman mosaics of Piazza Armerina (Enna, Italy)

3D digital imaging for the study of archaeology and the globaldissemination of knowledge is of growing relevance and has proven to beextremely beneficial in particular on cases study characterized by a poor digitalaccessibility. With seven Unesco World Heritage sites, Sicily has an extraordinaryheritage perfectly representing the cultural achievements of manyMediterranean civilizations, but yet the digital presence of such heritage is ratherlimited. The aim of this paper is to present the some methodological insights totackle issues of 3D digitization of mosaic floor via digital photogrammetry onthe basis of direct experience with the case study of the Roman Villa del Casaleat Piazza Armerina (Enna, Sicily, Italy). The virtualization of over 2500 m2 ofmosaic floord was carried out in the frame of an international collaborativeproject undertaken by University of South Florida's Institute for DigitalExploration - IDEx (former CVAST), in partnership partnership with theRegional Department for Cultural Heritage and Sicilian Identity and specificallywith the Regional Hub of Piazza Armerina, Aidone and Enna and the Universityof Catania's Departments of Civil Engineering and Architecture (DICAR),Mathematics and Computer Sciences (DMI), and Humanistic Studies (DISUM).
