Assessing the Volume of Defensive Structures for Architectural Energetics Analysis Using 3D Electrical Resistivity Tomography

Architectural energetics is a methodology that translates architectural objects into quantitative time-labor equivalent, from which information about past societies, labor organizations, or political relations can be inferred. Preceding such study, the volume of every structure must determined. This usually done by in situ measurements and computing mathematical formulae using UAV-based photogrammetry processed digital surface model. However, both these methods are impracticable case buried semi-buried monuments where only remaining option direct excavation. Hence, we introduce new method for determination volumetric based on electrical resistivity tomography (ERT) geophysical method. We conducted our study at defensive lines (ramparts/ditches) within two hillforts different ages, constructed building materials, Czech Republic. ERT surveys performed 3D differentiate ramparts/ditches detail surrounding environment resistivity. Compared to previous excavations, inversion results show obtain meaningful volumes chosen threshold. The best were achieved homogeneous ramparts ditch. fraction cost also leaves an intact site future generations.
