The greek – roman aqueduct: the three-dimensional reconstruction with terrestrial photography

Abstract. The current paper is a part of the scientific category HBIM, with ground photography and photogrammetric processing. The photogrammetry is an important tool for recording, storing, promoting and documenting buildings. The purpose of the work is to construct a three-dimensional model of the Greek-Roman aqueduct of the city of Kavala, in northern Greece. First of all, the aqueduct has a very important historical and aesthetic value for the city, because it is a tourist attraction. Also, it is an urban physical boundary, which separates part of the old town from the new roads of the coastal front. Moreover, the methodology was based on photographic shots, then on photogrammetric processing with Zephyr software. The methodology of the 3D model had as a purpose the terrestrial photography in a rapid and effective way. The result, of the work is the presentation of the three-dimensional model of the aqueduct, the analysis of the methodological steps of photogrammetric processing and the analysis of the historical transformation of the aqueduct area by a medieval and modern coastal city. The advantages of photogrammetric documentation have a role in the storage of the three-dimensional form of the historical building and in the smart promotion of its historical, touristic, urban aspects.
