Turning Point Clouds into 3d Models: The Aqueduct of Segovia

This article presents digital three-dimensional models that reproduce the original structure of the aqueduct of Segovia (Spain) using laserscanning approaches, as well as orthophotos, which thoroughly document dimensional and textural characteristics of this emblematic monument, declared UNESCO World Heritage Site. In addition to analyzing the accuracy and validity of laserscanning technique in the conservation and preservation of Cultural Heritage, a methodology of data capture, processing and photogrammetry representation is analysed.
