Welcome to Geotech!
What is Resistivity Imaging Systems?
Technical Definition & Core Principles
Resistivity Imaging Systems (RIS), also known as Electrical Resistivity Tomography (ERT), reconstruct subsurface resistivity distributions by analyzing voltage responses to injected currents. Geotech Series achieves 0.05m-resolution 3D imaging through 1024-channel quantum electrode arrays and real-time edge computing.
