An Interactive 3-Dimensional Database Applied to the Conservation of a Painted Chapel

International audienceMatteo Giovannetti's frescoes (1355-1356) which decorate the Innocent VI chapel of La Chartreuse du Val des Bénédictins (Villeneuve-lez-Avignon, France) are very sensitive to the alteration. They need a new restoration campaign. Because of the geometrical complexity of the place, the environment and the involved degradation mechanisms, a good conservation management of these murals is essential. Therefore, an interactive 3- dimensional spatial database, including dated data was developped. Architectural measurements, digital scientific documentation were gathered. A historical documentation including restoration acts, used restoration products has been collected. Last, the paintings degradations, up-to-date deterioration patterns description and conservation state diagnosis of these wall paintings including a deterioration mapping are monitored. Results of the physical and chemical analyses of painting, restoration techniques and deterioration products are also integrated. The entire collected and interactive database will be available for conservation managers and researchers within the next three years
