A method and apparatus (100) for determining a location of an underground object (108) during a digging operation. The method and apparatus (100) includes delivering a signal toward the underground object (108), receiving a reflected signal from the underground object (108), determining an initial location of the underground object (108), creating a region of uncertainty (110) around the underground object (108) as a function of a level of confidence of the determined initial location, performing at least one process to improve the level of confidence, and adjusting the region of uncertainty (110) as a function of the improved level of confidence. |
