Abstract
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.
Highlights
The research arises from the possibilities offered by point clouds obtained through massive data capture techniques, such as the Terrestrial Laser Scanner (TLS), for the study of heritage buildings
The methodology is applied in a structural bay of a Gothic apse, in this case, the apse of the Cathedral of Girona
It has not been possible to obtain some heights of the vault of the CR1 chapel due to the occupation of the space by the altarpiece
Summary
The research arises from the possibilities offered by point clouds obtained through massive data capture techniques, such as the Terrestrial Laser Scanner (TLS), for the study of heritage buildings. The objective of this communication is to establish a workflow to identify formal anomalies in the main structural elements The research is carried out using existing software to systematize an easy and agile methodology. This information can have an impact on heritage conservation strategies, and on historical studies. The Cathedral of Santa María de Girona is a large building with a high formal complexity In this context, the use of a TLS, allowed to obtain a topographic survey of the complex in 2019 (Coll-Pla, Costa-Jover, Moreno-García, Samper-Sosa, 2019), with unprecedented detail and precision (Figure 1)
