Patent ID: 8359162

Claim:
A computer-implemented method of processing measured potential field data from a moving platform potential field survey for mapping a field, the method being implemented in a computer comprising a memory in communication with a processor, the method comprising: inputting, to said processor, said measured potential field data, said 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, to said processor, terrain data defining a spatial variation of terrain surveyed by said potential field survey; determining, by said processor, time-domain correction data to be applied to said measured potential field data in the time-domain, said determining comprising: using said terrain data and said associated data defining positions of said measurements as a function of time; and compensating, by said processor, for a bandwidth of said potential field measuring instrument, wherein said compensating for said bandwidth comprises filtering, by said processor, said time-domain correction data using a filter matched to an impulse response of said instrument; and adjusting, by said processor, 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.
