Abstract:
1. A method on a mobile computing device for locating electromagnetic signals radiating from a buried asset, the method comprising: receiving, via a communications network communicatively coupled with the mobile computing device, a group of buried asset data points corresponding to a particular buried asset sought by an operator of the mobile computing device; reading a predefined value pertaining to a width of a buffer zone; generating, based on the group of buried asset data points, a two dimensional area comprising the 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 particular buried asset; iteratively executing the following four steps: a) calculating an above-surface location of the mobile computing device using spatial processes; b) determining whether the above-surface location of the mobile computing device 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 of the mobile computing device; and d) if the above-surface location is located within the two dimensional area, displaying a second graphic in the display.
