Le plan-relief informatique, outil de représentation des transformations urbaines

Abstract : In the Campus Martius in Rome, the Piazza Navona takes out the exact shape of the stadium built by Domitian in 81. The Ecole française de Rome startedthe archaeological study of the monument. Jean-François Bernard is at the head of this project financed by the French National Agency for Research (ANR). Understanding the ancient period of the monument required considering the topographical environment: how was the site for an urban program chosen to permit the creation of the “ludus capitolinus”. For each monument or each layout, great care is taken in the scientific justification of the choices. The survey of the archaeological knowledge has shown a development achieved in four phases. The 3D visualization of the site at four different periods requires the making of a virtual relief plan. It is based on the modern tradition of representing the city. This making has been entrusted to the Archeovision Platform situated in the Archéopôle in Bordeaux. At the end of the project, this work will result in the creation of a set of superimposable plans having in common limits, scale, style and coding to show in perspective the architectural and town-planning evolution of the area, from Antiquity to the XXth century. The difficulty of the bias is to create a basic model positively homogeneous but flexible enough to adapt to the various sights of the area. The drawing development process is another problem. The sector with the stadium and the Odeon is represented with very precise details. As for the rest, the incomplete documentation commands a working drawing. This method allows to bring continuous changes linked with the progress of research and immediate reaction to the discussion.
