3d photogrammetric documentation in the archaeology of the contemporary past: preserving the World War II landscape in north-west Sardinia (Italy)
Alessandro Panetta, Paola Derudas
Abstract Since the publication of Paul Virilio's “Bunker Archéologie” in 1975, there was an increasing interest in the archaeological study of the 20th century wars, especially WWII. This research take into account a database of nearly 200 surveyed and inventored military buildings and pillboxes built in 1943 for the coastal defense of the north-western Sardinia (Province of Sassari). Our aim is objectively documenting this particular archaeological record looking at its preservation both as a material and as a cultural heritage of european history, objectively, by the study of topographical organization of these buildings, their relationship with landscape and their internal space division according to their different tasks. We need to document this fragile heritage in his 'becoming archaeological', recognizing the historical and archaeological dimension of these often considered simply 'old' concrete buildings scattered in the countryside, before they becomes 'ruins', with their slow steady consumption. For this reason the target of the research is the preservation of the memory of war, by the preserving and knowledge of its physical scars like these buildings are. To do that, we propose the use of 3d documentation technique, for the development of this 'en plein air' museum, making it accessible also by remote devices, due to the often difficult access to them on the ground. The 3DHOP presenter was chose to reach the goal. It is a flexible framework that allows to manage and handle 3D contents, also big ones, in a very easy way and through a series of ready-to-use templates. It will possible to take digital tours of the buildings, both outside and inside of them and the visit will be enriched by connecting multimedia data, such as related historical information and images. Some details will be highlighted through zooming tools, useful to catch and direct visitors' interest to the main contents.
