ArcheoLogia Data 4/2024

3D reconstructions have become an efficient research tool for archaeology that permits scholars to visualize and study different hypotheses simultaneously. This paper will examine the methodological choices that led to the creation of a dataset containing elevation and plan measurements of centrally planned buildings in the Roman and late antique periods. By comparing the proportions of these structures, it’s possible to gather a set of common ratios that are helpful for reconstructing the volumes of these types of buildings. The dataset is presented as a CSV file, including spatial coordinates and metrological information about the proportions of 25 buildings constructed between the 1st and 6th centuries CE. Although the collected data are already present in paper form within the final appendices of several publications, the usefulness of this work lies in making these data more readily available and searchable. The creation of this type of dataset has the potential to speed up the reconstruction procedures and provide a more precise evaluation of reconstructive hypotheses through a wider range of comparative data. An illustrative case of the dataset’s practical application is demonstrated through its utilization in the reconstruction process of the hexagonal building at Villa dei Vetti. The paper will outline the dataset’s attributes, the data acquisition methods, and it will clarify how the collected information can be utilized in the field of 3D reconstructions of centrally planned buildings.
