Laser scanning and automated photogrammetry for the knowledge and the representation of the architecture cave in Cappadocia. Sahinefendi and the open air museum in Goreme

The survey of the "40 Martyrs Church" in Sahinefendi and churches located within the Goreme Open Air Museum is part of a research project oriented to test systems for surveying and representation applied to the architecture excavated rock. The data acquisition using old and new technologies and processing in post- production involves a necessary critical action that affects not only each specific monument, but the same methodology of acquisition and processing. In particular, we tackled the problem of systematization of procedures for the architectural survey in the field of rock art according to the “emerging” technologies like Laser scanning, automated photogrammetry and immersive photography. The rock architecture, unlike the one built, has the need to represent its particular, irregular, morphological feature, so it was necessary to conduct a trial of representation techniques unusual for architecture, most commonly used in cartographic representation, as contour lines and planar development of complex surfaces.
