Roxane Roussel holds a State Diploma in Architecture from the ENSA Marseille, with a research mention, and has since worked as a study engineer at CICRP and MAP-gamsau, focusing on the annotation and semantic enrichment of heterogeneous heritage data. She is currently involved in the construction of a digital report for the Notre-Dame de Paris cathedral as a member of the MAP laboratory.

An approach for the construction of a digital report and digital twin for the Notre-Dame cathedral after the fire

Since the fire of the Notre-Dame de Paris cathedral that took place in 2019, the scientific community has seized this singular framework in order to gather and build data on the cathedral, as well as assisting the restoration worksite. In this context, the « digital data » working group, coordinated by Livio De Luca, works to create a « digital ecosystem » by gathering and merging existing data, generating new data, archiving, and ultimately organizing and enhancing it with semantic features. This presentation here focuses on the work carried out in order to build a complete digital report of the Notre-Dame cathedral after the fire, using the aïoli platform. The methodology included the construction of 3D point clouds for sections of the cathedral, with the use of photogrammetry, then followed by the enrichment of the projects using annotations, description sheets and joined files in order to articulate the information emerging from the researchers and professionals (architecture, archaeology, history, computer science, chemistry, physics…). Furthermore, this ongoing work enables not only cross-checking of the data but also the ability to search for numerical information and evaluate the frequency of specific observations by using one or multiple targeted keywords.
