Mapping methods applied to Underwater Archaeology: the photoprogrammetrical model and the photomosaic of the Phoenician shipwreck Mazarrón-2 (Puerto de Mazarrón, Murcia)

Abstract

In 2007, ARQVA – National Museum of Underwater Archaeology carried out an archaeological project at the Phoenician shipwreck Mazarrón-2 (Port of Mazarrón, Murcia, Spain). The aims of the project were to check the state of preservation of the hull remains of the ship as well as the metal structure that protects the site. Moreover, the available archaeological data on the shipwreck were updated for the purpose of creating a new digital archive of the site. A real scale photogrammetrical 3D model of the interior of the hull of the ship was created using the program Photomodeler. In addition, a high-resolution photomosaic of the ship was produced since this had not been done in the past. This article describes the methods employed in the realization of both the photogrammetrical model and the photomosaic. Finally, an evaluation is offered of the applications of these recording techniques for archaeological hull remains underwater.
