Documentation of Cultural Heritage Monuments, by Introducing New Surveying Technologies Implementation in Sarlitza Pallas, in Thermi Mytilene

Visualization in 3D is an effective way to analyze and represent the environment of a building, especially if it's Cultural Heritage. Technology development of standardized methods can be very motivating for researchers of different sciences to integrate 3D modeling in their jobs. A key question is if it is possible for these methods to reach or maybe exceed the accuracy of classic geodetic methods and specifically those that are using total stations. Digital documentation combined with innovative analytical techniques and digital tools can be an effective strategy to support transdisciplinary documentations and modeling aimed at conservation, enhancement and preservation of Cultural Heritage. This paper presents the comparison between the two methods of documentation, classic and digital. Research object is Sarlitza Pallas, a small, historical and noted hotel which is based from 1909 in a small village called Thermi in Mytilene, Greece. A geometrical documentation has been done (elevations, floor plans, cross-sections), by using a conventional reflectorless total station. As regards the digital documentation and the 3D model of the hotel, have been produced by using a modern Multi-Station. The result was the documentation of Sarlitza Pallas with two different methods and their comparison, in order to assess the overall time and accuracy of derivative product and the capability of Multi-Station autonomous use in similar studies of Cultural Heritage monuments.
