Electrical Resistivity Tomography (ERT) is a remarkable tool for characterizing the geometry and properties of the regolith. However, its use for large horizontal surveys remains cumbersome to characterize shallow subsurface structures due to the requirement of small electrode spacing increments. Here we propose a new approach to overcome this limitation. We demonstrate that our protocol significantly improves the accuracy of ERT profiles when using large electrode spacing increments.
