3D SURVEYING AND FORMAL ANALYSIS OF A STRUCTURAL BAY OF A GOTHIC APSE

Abstract. In recent years, the development of massive data capture techniques such as Terrestrial Laser Scanner (TLS) have made it possible to develop new procedures to evaluate architectural heritage with a high level of accuracy. The study proposes a workflow to identify formal anomalies in the main elements that form a structural bay of the apse of the Cathedral of Girona, studying arches, vaults, buttresses and pillars. The methodology is based on different two-dimensional and three-dimensional procedures, and the database obtained that could help in future research to relate the results with the different construction phases and being applicable to other constructions of similar typology.
