Algorithms of processing data of gravimetric survey in a mountainous area

© Dolgal A.S.

Algorithms of processing data of a gravimetric survey considering the strikingly parted character of the observation surface relief are presented. The technology of determining topographic corrections in calculating Bouguer anomalies is improved. A method of statistic estimation of topographic correction determination accuracy based on the Monte-Carlo method is proposed. A method of interpolating and transforming discrete gravity field values based on the source - shaped analytical approximation is worked out. Model and practical examples illustrating abilities of the formed algorithms are given.
