GeoTDR
Time Domain Reflectometry (TDR) is commonly known as "cable radar" and was initially used by the cable TV and communications industries to find problems in coaxial cables. This time-tested technology was adapted by GCI's Kevin O'Connor to monitor movement of foundations, roadways and slopes as well as changes in groundwater conditions and soil moisture. Coaxial cables and probes are used for remote automated surveillance of large volumes of soil or rock.
