DOCUMENTATION OF ARCHAEOLOGICAL STRATIGRAPHIC UNITS. NEW DIGITAL TECHNOLOGIES APPLIED TO THE BURIALS IN SANT’ANDREA IN MOMBASIGLIO

Abstract

Archaeological site activities are extremely destructive. To understand how civilizations have developed, archaeologists have to remove layers and layers of land to find evidences of their theories. An important task for researchers is to accurately document every single detail of the site before the definitive removal of precious information. Position, orientation and the context where findings are located could represent important data to be stored and compared many months after excavation process. Survey operations during site activities has to be considered extremely important, since they have to immortalize a particular moment of past human activities before its destruction. Despite this, most of the time archaeological records consist of two-dimensional representation of three-dimensional subjects. In recent years, the spreading of techniques to digitally document heritage assets have allowed to tested new approaches also in archaeological fields. Using digital cameras, drones and laser scanners it is possible to collect a multitude of details, such as textures, materials, decay phenomena, and to collect all these data inside 3D models. Digital techniques for documenting archaeological site has been tested during excavation campaigns in Sant’Andrea in Mombasiglio church, in the northern of Italy. The site has been documented along many years and in different excavation progresses, to be able to digitally recreate multiple stages of site evolution. 4D stored information can be used by archaeologist for scientific purpose, as in the museums through VR and AR applications.
