| Abstract: | The calculation method of normal splins function is introduced firstly in this paper. Based on this, the monavariable normal splines function is generalized to thin plate splines, which is defined on multidimensional space. Then the using of this function to express the surface such as desert terrain is discussed. At last method of DEM building is given. |
