The Digital Narrative of the Eladio Dieste’s Church in Atlantida, Uruguay, by Tools Integrations Analyses

This research focuses on the Church of Cristo Obrero y Nuestra Señora de Lourdes, located in Atlantida, Uruguay, which was designed by Uruguayan engineer Eladio Dieste from 1956 to 1960. This architectural work is significant because of the experimental innovations in structural design and construction technology implemented by Dieste. The Church of Cristo Obrero y Nuestra Señora de Lourdes was the foremost application of continuous Gaussian vaults in reinforced brickwork under thin-shell roof modules by the engineer, together with governed surfaces on its lateral walls. The tools integration adopted during the on field research wants to demonstrate how current technologies could be used and combined to obtain a reliable database. The digital description was carried out by the 3D survey blending 5 different source of data (terrestrial lidar (2 tools), terrestrial photogrammetry, aerial photogrammetry, and slam technology). The result of the data comparison aims at highlighting a suitable and affordable methodology in terms of data capturing through the integration of the tools currently available on the market. To evaluate the geometric-morphological quality of the obtained point clouds, the one acquired with Leica c10 was used as a metric reference for analyzing deviations of other tools.
