| Abstract: | The authors calculated the terrain correction of 764 points in 1:200 000 regional gravity survey performed in northwest Qilian Mountain by using 20 m×20 m, 50 m×50 m and 100 m×100 m square grids. Based on a discussion of the gravity terrain correction method, this paper studied the simulation degree and terrain correction precision of every computation method through moving square grids. |
