Preliminary data processing on the Roman Shipwreck of Grado. Archive and legacy data to create its 3D virtual model

Ca’ Foscari University is working on different archaeological topics to enhance knowledge about shipwrecks through digital technologies applied on data archive and legacy data, from a wreck of a Napoleonic brick to cargos of amphoras of Byzantine and Roman period. The potential of digital technologies has allowed us to analyse and elaborate different kind of documentation, also of archive, to obtain 3D models that could be studied and visualized with innovative solution and technologies. The paper presents an original proposal to create a 3D virtual model on an ancient shipwreck from archival and heterogeneous data. On the Grado Roman shipwreck, we have processed the data of perspective drawings of the shipwreck and the amphoras, of measurements during the excavations, of digitalization of analogical images and of the survey of the cardboard scale model to obtain a complete virtual 3D model of the shipwreck.
