Survey and virtual restoration: The Castle of Magacela (Spain)

This paper present an application of the latest sensing technologies in the field of restoration is presented. The object of study is a Castle built in different historical periods by different hands so it has undergone changes, deformation and partial replacements. The aim of the survey is to study this issues looking for a common denominator that makes them more understandable. The results of the research are constantly compared with the hypotheses, avoiding in this way the typical contradictions of isolated analysis. The different phases of data acquisition were characterized by the implementation, analysis and comparison of different survey methods: GPS, total station and laser scanner. The results were used to design an appropriate restoration. The use of 3D modeling for attempting the conservation and the revaluation of cultural heritage is having an increasing role. For this reason, it is important to have a high level of detail, and at the same time obtain a model of easy interactive visualization. Therefore, this study is the first attempt to enhance and promote the archaeological heritage through three-dimensional virtual reality. This will allow the visitor the opportunity to transform his role from a simple viewer to an active subject, to virtually `live´ the ancient site, its forms and spaces with a more dynamic participation.
