Rilievo, documentazione e ricostruzione di un centro monumentale con fotogrammetria e modellazione tridimensionali: il caso della città romana di Sala

The paper analyses the practise of surveying and reconstruction of the buildings in a Roman North Africa monumental centre by means of photogrammetry and three-dimensional modeling. Photogrammetry, in particular, proves to be an efficient and economic method for field analysis, although it has limitations in terms of processing time and the need for very powerful computers. Photogrammetric models, characterized by a high volumetric and colorimetric quality, constitute an ideal basis for reconstruction by means of 3D modeling, particularly in the case of research, such as this one, related to the Archaeology of Construction.
