Abstract: Conducting a potential field survey of a survey surface includes a method, a system, and/or a non-transitory computer-readable storage medium. In some embodiments of these techniques, the method includes determining a set of paths along an observation surface at an observation height above the surface survey, and measuring potential field data at points on said paths, wherein said set of paths comprises at least one reference path and a plurality of survey paths associated with said at least one reference path wherein the distance between each of the plurality of survey paths and the reference path is a function of the observation height. Said set of paths may define a generally fan-shaped pattern diverging from a common region. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.
