ABSTRACT
The laser scanner is a high precision tool with which certain aspects can be quantified in order to evaluate objectively the conservation of cultural heritage. A Leica ScanStation C10 laser scanner has allowed to obtain the planimetry of Santa Magdalena church (Seville, Spain). The generated model is a high density point cloud with the degree of detail of a millimeter, from which metric calculations can be performed. In order to evaluate the damage of the vaults and to analyze the potential damages produced over time, length and width measurements of cracks were conducted. In this case, the model allows to detect cracks between 2–20mm and length up to 7.2 m. The monitoring with 3D Laser scanning allows to analyze the vulnerability and the damage evolution of monuments, and it could be a very useful tool to forecast the preventive conservation.
