16th International Symposium on Boat & Ship Archaeology

102 16 th International Symposium on Boat & Ship Archaeology Tea Katunarić Kirjakov Arts Academy in Split, Croatia Using 3D technology for documentation and interpretation of newly discovered shipwrecks and underwater sites near the islands of Šćedro and Hvar, Croatia The island of Hvar and the small, isolated island of Šćedro adjacent to it are sit- uated in the middle of the Eastern Adriatic Coast. They are located on the most significant navigation route in the Eastern Adriatic. Both islands were inhabited from prehistoric to present times due to fertile plains, sources of fresh water and protected and safe coves. The only connection with other islands and the main- land were through maritime routes. Therefore, there are numerous archaeologi- cal underwater sites around those islands that have been recorded and explored for more than 200 years. In the last few years, thanks to great collaboration with the local population, divers, and fishermen, several new sites of intact shipwrecks were discovered. These include two shipwrecks with cargo of amphoras from the Roman Republican period located near the island of Šćedro, a Late Roman ship- wreck with ballast stones, and the cargo of a boat from 16/17 th century located in the Stari Grad Bay on the island of Hvar. The shipwrecks were recorded using 3D technology. More than 4500 photographs were shot and processed to obtain pre- cise 3D model of the sites. 3D models were analysed in detail regarding the typol- ogy, determination and amount of the cargo, shape, dimensions and dating of the vessel, circumstances of the wreckage, as well as their interaction with terrestrial and submerged sites on the islands such as pier and villa maritime on the island of Šćedro and the Hellenistic and Roman port of Pharos/Pharia on the island of Hvar. All those locations were also documented by 3D scanning. In addition to the precise documentation of those sites, 3D models assist in the development of guidelines for future excavations as well as site protection and VR presentation.
