Abstract
A method on a mobile computing device for locating a buried asset is provided. The method includes receiving a data structure that represents a two dimensional area comprising a buffer zone at an above-surface location, wherein the buffer zone corresponds to a particular buried asset sought by an operator of the device and iteratively executing the following steps: a) calculating an above-surface location of the device; b) determining whether the above-surface location of the device is located within the two dimensional area; c) if the above-surface location is not located within the two dimensional area, determining whether a locating function of a component coupled with the mobile computing device is enabled, and if so, disabling the locating function; d) if the above-surface location is located within the area, determining whether the locating function of the component is disabled, and if so, enabling the locating function.
