Abstract

With this contribution we want to show how acquisition, management and analysis of the three-dimensional component of archaeological data can improve the understanding of the formation of different contexts and, in particular, the construction history of a historic building. The introduction of a new generation of lighter and cheaper 3D laser scanners and the dissemination of web service, open source and low-cost software for digital photogrammetry have triggered a debate about their proper use in archaeology. Previous research has left a number of problems open and the proposed solutions cannot be considered yet fully satisfactory. In the first part of the article we will outline the limits of the current standards of archaeological documentation and describe the possibility of integration of these new tools into the operational practices, with particular emphasis on photogrammetry. In the second part we will propose an example of archaeological analysis of the Nuraghe of Tanca Manna (Nuoro) using unconventional methods and tools: a system of shooting on telescopic pole (featuring remote control of the camera to the ground and preview frame); the combined use of free cloud computing and commercial software for automatic modeling of architectural surfaces; a dedicated electronic procedure to document the wall stratigraphy and the shape of the structural elements on the 3D model; data management in a GIS environment; the use of PDF3D as standard format for the exchange and use of three-dimensional content. In conclusion, we will attempt to demonstrate the added value of this workflow compared to the normal operating procedure, emphasizing the versatility, speed of execution and the improved information content of final papers.
