Abstract
In some embodiments, content is generated that includes a street map, at least one path on the map indicating a route of travel by a mobile gas measurement device, and at least one indicator on the map that indicates a survey area for a potential gas leak source. The survey area adjoins the path and extends in a substantially upwind direction from the path. The survey area has a boundary determined such that if the potential gas leak source is located in the survey area and has a rate of leakage meeting a minimum leak rate condition, then an estimated probability of detection of a gas leak from the potential source at one or more measurement points along the path satisfies a probability condition.
