| Abstract: | By using Shepard surface fitting method,weight moving trend surface fitting method and ordinary Kriging method,the anomalous gravity data were interpolated for gridding and then the gridded data results were compared with each other in calculating speed,continuity of gridded surface,the accuracy and the suitable fields of application.It is verified that:1)the accuracy of gridding result;would become nice if the discrete data points are even in the same area and the initial data are enough;2)the Ordinary Kri... |
