Abstract
A method of processing measured potential field data from an airborne or marine potential field survey to determine a set of field mapping parameters for mapping a field, the method comprising: inputting said measured potential field data, said measured potential field data comprising data defining a plurality of potential field measurements each with an associated measurement position and measurement time; and determining said set of field mapping parameters using an equivalent source model, wherein said determining comprises fitting said measured potential field data to said model wherein said measured potential field data comprises at least one set of potential field measurements each having associated measurement positions which are sufficiently close that any residual noise component is attenuated by a factor of the square root of the number of measurements in said at least one set.
