Abstract
A method on a mobile computing device for locating electromagnetic signals radiating from a buried asset is disclosed. The method includes receiving buried asset data points corresponding to a buried asset, reading a predefined value, generating, based on the buried asset data points, a two dimensional area comprising a buffer zone at an above-surface location, wherein a width of the buffer zone corresponds to the predefined value, and wherein the buffer zone corresponds to the buried asset, and iteratively executing the following four steps: a) calculating an above-surface location, b) determining whether the above-surface location is located within the two dimensional area, c) if the above-surface location is not located within the two dimensional area, displaying a first graphic in a display, and d) if the above-surface location is located within the two dimensional area, displaying a second graphic.
