| Abstract: | If radius of topographic amendment is inclined to be small when data of gravity surveys is processed, dependability of information will be reduced. If it is inclined to be large, manpower and finances will be wasted. As physics-mathematics model of topographic amendment is created,it have been put forward to select method of largest radius about topographic amendment. |
