Survey and elaboration of digital data for a stratigraphic analysis of pluristratified contexts: the s.c. Domus degli Americani (Palatine, Rome).

With this contribution, we would propose and discuss the digital technologies methods, strategies and procedures about acquiring and elaborating data, focusing on the case-study of the s.c. Domus degli Americani (Palatine, Rome). The monument is a late-antique domus along the eastern slope of the Palatine Hill. Today, it lies within the limits of the Parco Archeologico del Colosseo in the area investigated by Sapienza University (Prof. M.T. D’Alessio). It dates from the third to the fourth century AD, constructed in place of earlier structures, varying in functions and erected since the fourth century BC. The building was excavated between 1989 and 1993 using a stratigraphic method by an international team led by Hostetter and Howe (AAR). Latest documentation has been produced by Parco Archeologico del Colosseo. The context is of primary topographical, historical, and architectural significance, requiring a thorough analysis of the published, sometimes incomplete, documentation and visible stratigraphy. It is of the outmost importance to gain a deeper understanding of a monument which to-date has been only partially read from a diachronic perspective and in its proper context. Field and laboratory analyses are still ongoing. The aim is manifold: acquiring new data, verifying, and integrating information already published by AAR and in historical cartography. Our work is divided into an initial survey phase, in plan and elevation, of each evidence, utilizing GNSS antennas (Leica GS15), total stations (Leica TS15), laser scanners (Leica RTC360), photogrammetry. The new graphic documentation makes up the base for an autoptic stratigraphic analysis of the visible evidence. This approach allows diachronic interpretation of the monument and its narrative over time. All data is acquired and processed digitally. Our goal is to apply a methodology that is as precise and effective as possible, crucial for the required level of detail, involving interoperability between tools and operators.
