Reconstructing the development of architectural complexes throughout time is often very diffcult. Buildings are usually a series of constructive actions, changes from the original project, and also collapses and reconstructions due to human actions (such as demolitions) and/or natural (earthquakes, foods, etc.). The building’s structure records all these events, giving us the chance to understand and decode them through the relief. The archaeological relief is thus supposed to offer a complete and rapid documentation. At the same time, it must be enriched with all the information needed for a deeper analysis of the archaeological object itself. In the last years, the introduction and continuous improvements of many instruments (e.g. laser scanners and photogrammetric technologies) have led to a sensible qualitative and quantitative change in the recording of the material structure.

In particular, the possibility to combine different relief technologies – obtaining high resolution, 3D geometrically correct models of buildings or of entire archaeological sites (which could be further investigated thanks to archaeological analysis or other procedures), has modified the archaeological approach towards the material “datum” and its divulgation. In order to achieve a better knowledge of nowadays technologies, the divulgation of different employed methodologies – through their application in research contexts – is the best way of transmission and comparison. This contribution is dedicated to the presentation and detailed analysis of a photogrammetric RGB point-clouds technology, used for the relief of a living-room during the archaeological excavation at Aiano-Torraccia di Chiusi (City of San Gimignano).

During the years 2006-2007, three teams of scientists (archaeologists with geophysicists) detected the archaeological surface of the Late Antique villa at Aiano-Torraccia di Chiusi (Siena, Tuscany) using GPR (Ground Penetrating Radar), Resistivity and Magnetometry. Their aim was to identify archaeological remains and consequently spend less time and money on digging. At the conclusion of the fieldwork and data treatment, they used a CAD program to overlap geophysical and archaeological layers and check geophysical results on archaeological remains. Despite surveys in many other archaeological sites, they obtained few results: surveys located anomalies in less than 1/4 of the archaeological remains excavated in 2008 and 2009. In this paper the authors attempt to analyze (and try to find better solutions for the future) errors in the geophysical surveys caused by incorrect calibration of the database, low accuracy of grid intersections and excessively long grid lines, in relationship to site conditions and the kinds of archaeological remains. These technical problems in fact certainly create a less than optimal operational synergy between archaeologists and geologists during the post-processing of the data: an analysis of these problems may help to improve future projects of this type.
