La Basilica di San Lorenzo in Lucina a Roma: sviluppi di un processo digitale e diagnostico per la conoscenza e il monitoraggio delle condizioni conservative

The paper is part of a research aimed at the establishment of investigation protocols for the study of materials, construction techniques and conservation state, through expeditious diagnostic procedures, in stratified architectural contexts and describes the experimentation of a digital procedure for the information of a three-dimensional model of the basilica of San Lorenzo in Lucina in Rome, obtained through the use of a laser scanner. The results of the diagnostic investigations conducted inside the basilica are organized in synthetic reports designed to be traceable and geo-localized on the point cloud. The virtual environment is able to host location and diagnostic survey data, promoting the correct interpretation of relationships and consequently the global and cross-sectional understanding of architectural elements, materials and forms of decay. The digital model would represent an archive of geo-referenced and stratified data that would allow future researchers to start from an easily accessible and implementable knowledge base. This would cut down search and survey time and costs in the diagnostic process, ensuring both sustainability and completeness of information requirements.
