Calculation and analysis of the new statistical character parameters of gravity field in China
|
Abstract:
New statistical parameters of covariance and commission error model of complete Bouguer anomalies and Faye anomalies are constructed using terrain information. Statistical analysis is made with the gravity and terrain data in test area, and the calculation scheme is extended to the statistical computation of great areas and various regions in China. Statistical parameters of variance and covariance and commission error model of the above-mentioned gravity anomalies are given in six different terrain regions, such as plain, hill, little mountainous region, medium mountainous region, big mountainous region, and outsize mountainous region. The results show that the grid value, contour map, etc. of complete Bouguer anomalies and Faye anomalies in China can be obtained from the metric data according to the statistical parameters and methods and thoughts in the paper.
