| Abstract: | The basic principle of TPS is introduced.TPS is applied to interpolation of spatial data of Changzhutan Area in Changsha province based on independent development of the city’s three-dimensional geological modeling and visualization software system by VC 6.0.Finally,the interpolation results of TPS are compared with true crossing-validation method to sample data and other interpolation method.It proves that TPS is an effective method of interpolation of the city’s 3D geological modeling. |
