In this paper we will face up methodological and technological problems on the virtual reconstruction using OpenGL software in order to project, reconstruct and explore archaeological landscape in real time. The "Appia antica" project is an extraordinary case study in which different technologies were tested and used in integration: remote sensing, laser scanning, mono and stereo photogrammetry, photomodelling, DGPS RTK (real time kinematic), GIS. Technologies used are addressed towards two research directions: the first one is related to the topographic and architectural documentation of monuments for GIS and spatial archives, the second one to the creation of a virtual reality system dedicated to the narrative museum of Appia Antica Park. Scientific, geographical, anthropological, cultural, narrative aspects are all together constitutive elements of the history of the archaeological landscape, they belong to its memory. How ancient people lived in the territory? What kind of activities they developed? Which symbolic values they attributed to the places? What kind of relations they established with the territory and in consequence among them? 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.
