摘要
A method of locating an underground utility line. A first step involves securing transponders along a length of an underground utility line at regular spaced intervals. A second step involves interrogating the transponders to receive transponder signals. A third step involves ascertaining the position of the transponder signals and extrapolating positioning of the underground utility line from the transponder signals.
