A method for processing data from potential field surveys, particularly airborne gravity field surveys, to correct for the effects of terrain comprising: inputting measured potential field data comprising data defining a time series of potential field measurements captured by a potential field measurement instrument mounted on a moving platform, each of said measurements having associated data defining positions of said measurements as a function of time; inputting terrain data defining a spatial variation of terrain surveyed; determining time-domain correction data to be applied to said measured potential field data in the time-domain, said determining using said terrain data and said associated data defining positions of said measurements as a function of time; and adjusting said measured potential field data defining said time series of potential field measurements using said time-domain correction data to provide terrain corrected measured potential field data for said mapping of said field. |
