The virtual reconstruction of archaeological landscape: from the fieldwork to the communication through real time applications. The digital narrative museum of the Appia Antica Park

In this paper we will answer methodological and technological problems of the virtual reconstruction using OpenGl software in order to project, reconstruct and explore the archaeological landscape in real time. The “Appia antica” project is an extraordinary case study able to integrate different spatial technologies: remote sensing, laser scanning, mono and stereo photogrammetry, photomodelling, DGPS RTK (real time kinematic), GIS. Technologies used are turned towards two research directions : the first one is the topographic and architectural documentation of monuments for GIS and spatial archives, the second one is the creation of a virtual reality system dedicated to the narrative museum of the Appia antica. Scientific, geographical, antropological, cultural, narrative aspects are all together costitutive elements of the hystory of the archaeological landscape, they belong to its memory. How did ancient people lived in the territory? What kind of activities did they develop? Which symbolic values did they attribute to the places? What kind of relationship did they establish with the territory and in consequence among themselves? These are the main questions a project of communication should face. It is very important to preserve the link between the fieldwork and relief activities and virtual reality communication. For this reason our efforts have been oriented to experiment and find a common protocol to manage data, without loosing information during the successive phases of elaboration and communication.
