Integrated survey techniques for the study and the restoration of the archeological heritage

The safeguard and the valorization of the archeological heritage are, especially in Italy, a privileged field given the richness of the classic and late-ancient sites. This interest implies always new and advanced instruments aimed at their knowledge, restoration ad valorization.This paper presents some works where an integrated survey approach has been used to analyze and to plan the conservation of an archaeological site in Piedmont. The characteristic complexity of the archeological sites involves both instrumental and direct survey techniques. An example of particular interest is here illustrated: the theatre of Libarna. The synergetic use of traditional and innovative techniques allowed: - in the acquisition step, a more accurate survey from the metric point of view - in the restoration step, a more punctual analysis of the state of preservation (materials and pathologies) - in the valorization step, a more immediate reading and communication of the obtained results and of the proposals for intervention (re-functionalization, image communication, virtual reconstructions....).
