Rilievo e ricostruzione virtuale del Ponte Sud di Hierapolis di Frigia (Turchia)

Abstract

The paper concerns the topographical survey and the 3D reconstruction of a Roman bridge-aqueduct located immediately to the south of Hierapolis in Phrygia (south-western Turkey), along the ancient route directed to Colosse and the internal Anatolia; only its southern abutment and scarce remains of the northern one are preserved. It is in a very difficult location, inside the narrow and deep valley, and it was never studied before. During the 2011 field work campaign of the Italian Archaeological Mission, it was surveyed using a high precision differential GPS system (for the plan documentation and its positioning in the digital archaeological map of Hierapolis) and through a Motorized Robotic Total Station (for the documentation of the elevation and the creation of a 3D model of the southern side) with the aim of its virtual reconstruction.
