This invention relates to methods, apparatus and computer program code for processing data from potential field surveys, particularly airborne gravity field surveys, to correct for the effects of ter rain. We describe a method of processing potential field measurement data from a moving platform survey for mapping a field, the method comprising: inputting measured potential field data comprising data defining a time series of potential field measurem ents 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. |
