Digital investigation on the Bridge of Augustus and Tiberius in Rimini. Changes in scale over time

Ancient bridges exemplify a domain where the acquisition phase is greatly impacted by the environmental conditions of the surrounds and the level of detail needed for the representation phase, in a sort of from S to XXL framework of documentation. The Bridge of Augustus and Tiberius, or Pons Tiberius, in Rimini, Italy, stands as a testament to the enduring legacy of Roman engineering and the historical significance of ancient infrastructure. Spanning the Marecchia River, this iconic bridge has a rich history that weaves together elements of Roman imperial power, architectural innovation, and cultural heritage. This study is part of a research project that seeks to enhance our understanding of ancient Roman stone bridges in Rome and the Provinces. It involves integrated survey activities, which are conducted to gather data for specific technical, geometric, and metrological analyses. The study utilises advanced technologies such as virtual reconstruction and three-dimensional modelling. The survey exploited conventional approaches such as topographic and GPS, as well as advanced techniques including 3D laser scanning and digital photogrammetry digital. This techniques showed how the bridge's role as a grand entrance to the Roman city can be remembered through several way of representation.
