Comprehensive analysis of interpolation methods for modeling the spatial distribution of gravity anomalies
Modeling the spatial distribution of gravity anomalies requires accounting for numerous factors that influence the accuracy of results. The primary factors include the interpolation methods used to construct regular grids of gravity anomalies, as well as the distribution and number of observation points. This study compares the accuracy of various interpolation methods for gravity anomalies based on the WGM2012 model. The analysis utilized gravity anomaly data obtained from 200 GNSS stations located in Ukraine and 355 test points of a hypothetical gravimetric network.
