| Abstract: | The grid model is common in the reconstruction of the three-dimension terrain.This method has some advantages,but there are some problems needed to be studied,such as how to insure the right elevation of the grid point,how to deal with the abnormal data,how to get the better effect and so on.These problems are analyzed,some methods are presented to solve them and an example is shown for validation. |

| Keywords: | grid model three dimension terrain abnormal condition positive data |
