Three-Dimensional System for Conservation and Valorization of Archaeological Sites

The cultural heritage, for its historical and artistic value, is a treasure that represents the identity of the society living with it. The conservation and valorization of an archaeological site need a rich documentation of their history and physical and geometric characteristics. Using correct documentation, one can grasp the diachronic complexity of an archaeological site; the purpose is to preserve and to hand on the cultural heritage. The different issues that arise in different surveys demand different instruments. The instruments operate without uniform accuracy and have different reference systems, but they must be integrated. To understand the purposes of the relief is fundamental in order to choose the procedures and the development of the methodologies. The most influential aspects are determined by the complexity of the elements to be represented and interpreted, by their dimensions and their accessibility. The 3D laser scanner is a consolidated presence among the tools available for the spatial data acquisition. Such instruments of measure concur to determine, with facility and rapidity, the position of numerous points inside the archives of the three-dimensional database to be consult and used at any time. The databases attribute scientific value to the information and make it possible to become acquainted with the geometry of the acquired subjects, also in order in order to spread knowledge. Three-dimensional databases exalt not only the informative-spatial aspect of the topics found through their geometric acquaintance, but are also crucial for communication. It is fundamental to open up new possibilities of data integration and treatment in order to favor the possibilities of geometric representation and to help it become known to the community in the simple and communicative way of a virtual reality. The study cases make reference to integration of various technologies for the survey of the architectonic structures in the archaeological area of Doclea, and to the application of laser scanner methodologies near some megalithic temples of Malta
