Archivi digitali 3D per la gestione di siti archeologici: i templi megalitici di Malta

The project is based on knowledge of the megalithic temples of Malta to support their use and management. This is particularly the temple of Ggantjia in the island of Gozo and those of Mnajdra, Hagar Qim, Ta Hagart and Skorba in the island of Malta. giant megalithic monuments, among the most unique and fascinating in European prehistory, whose poor storage conditions have prompted local authorities to develop a program of activities for their protection. Given the typological and morphological characteristics of the sites have been used for integration of different integrated methodologies of survey to correlate the ancient and modern surveys, creating a support for data management from a scientific point of view and from the point of view of diffusion. As part of the documentation of the research focused on data files of different origin and acquired through different methodologies which three-dimensional laser scanner, photogrammetrical and topographical survey. The evolution of technology has facilitated the construction of three-dimensional databases has allowed us to build a prototype digital archive not only for 3D geometric configuration of the property for the protection and conservation, as well as containers for different types of information. The three-dimensional models can be used in the virtual reality, for the restoration and to scientific scopes or for the public in the museums. The three-dimensional models, therefore, constitute a database of dynamic type on which to insert the information of historical, cultural and diagnostic type, with the objective to integrate the digital model 3D to an information system.
