Damage detection historical building using mapping method in music school of the University of Guanajuato, Mexico

Researchers developed a monument-mapping method to efficiently detect and quantify weathering damage on historical buildings, focusing on the Music School of the University of Guanajuato, Mexico. This approach identified five key forms of stone decay—fractures, salts, oxides, scaling, and lichen—using digital image processing. The study also characterized less-known decorative stones used in 18th- and 19th-century structures, providing mineralogical and petrophysic insights. By mapping damage size and location on green sandstone, the method offers a rapid, qualitative, and quantitative assessment tool for conservation efforts at UNESCO World Heritage Sites like Guanajuato.
