When presenting the history of a heritage site or an artifact using multimedia technology, the use of spatial information is very important in order to facilitate an understanding of that particular site and the relationship between the elements constituting that site. In many cases, one has to model complex environments that have a rich historical content. These are composed of several objects with various characteristics and it is essential to combine data from different sensors and information from different sources. There is no single approach that works for all types of environment and at the same time is fully automated and satisfies the requirements of every application. A general approach combines information from historical material, multiple images, single images, range sensors, known shapes, CAD drawings, existing maps, survey data, and GPS data. This paper presents the work that was accomplished in preparing multimedia products for cultural heritage interpretation and entertainment. Data fusion techniques were applied to three cases: the Byzantine Crypt of Santa Cristina, Apulia the remains of Temple C of Selinunte, Sicily and a fully frescoed Neolithic cave.
