Abstract

This article presents a multidisciplinary study to evaluate the internal and external state of underground wine cellars. In particular, five historical subterranean wine cellars that present a complex structure and whose underground three-dimensional (3D) shape and their connections with the external surface are unknown. They are recorded and analyzed with non-invasive techniques. An approach that integrates surveying geotechnologies (terrestrial laser scanner, global positioning system) with geophysical prospecting equipment (ground penetrating radar, electrical resistivity tomography), was used in order to plan architectural restoration actions. The combination of both sets of techniques implies an improvement in the information gathered compared with they are applied separately, facilitating the interpretation of geophysical data to generate accurate geometric geophysical profiles and highlighting the evaluation of the state of this type of architectonic heritage.
