Abstract

The ‘Progetto Shawbak. Ricerca, conservazione e valorizzazione del Crac’ de Montreal is a multidisciplinary project conducted by the Florence University Chair of Medieval Archaeology. An important objective of the work, pursued with the collaboration of Dr. Pierre Drap, Chargé de recherche at CNRS LSIS UMR 6168, is the realization of a 3D archaeological information system to manage a big amount of textual and graphic data. For this reason we tried to create a system that could handle all archaeological data in a single database that allows us to connect the 3D information derived from photogrammetric surveys with other archaeological records. Showback system is being tested on some Shawbak castle upright structures, including the huge Ayyubid Palace and a second site at the gate wall, and it aims to achieve the production of 2D and 3D representations through the queries it answers. This approach can obtain 3D representations of issues (e.g. possibility to see the USM of a particular phase in all analyzed buildings of the site) as well as new archaeological analysis (the development of quantitative analysis on the use of materials, the possibility of obtaining chronological data of the bricks, etc.). Finally, this research has led the Italian-French team to discuss the physics and stratigraphic relations at the basis of the Harris matrix.
