Digital Survey for the Archaeological Analysis and the Enhancement of Gropina Archaeological Site

This paper concerns the path of knowledge that leads to the understanding of the morphology and evolution of the archaeological area discovered in the 1960s below the parish church of Gropina (AR). By dealing with archaeological surveying methods, the attention is focused on the digital survey technologies used, integrating data from laser scanner instruments with photogrammetric ones. The morphological base was necessary for the preparation of stratigraphic analyses, and allowed us to check the previous studies carried out on the building to extract a periodized planimetry. Finally, the digital drawing technologies have allowed us to hypothesize the schematic evolutionary models of the different phases of the building, and to use the digital survey to create a virtual platform through which to interact with the archaeological site, which is now closed to visitors.
