FIELD: physics. ^ SUBSTANCE: described is a method of processing potential field measurement data obtained from surveying the Earth's potential field in order to determine map data for mapping the field. The method comprises steps where potential field measurement data are entered. Potential field measurement data include data which give the set of potential field measurements and corresponding positions. Each position gives the potential field measurement position in three-dimensional space; the set of relationships between potential field measurements and positions is determined. Each relationship links the potential field measurement with the function of the corresponding position in three-dimensional space, multiplied by the field mapping parameter; and an essentially self-consistent set of field mapping parameters for the set of relationships is determined in order to determine mapping data. ^ EFFECT: improved data processing methods. ^ 29 cl, 4 dwg |
