| Abstract: | Through a case of SRTM over nine vacancies of different size classes and three terrain types including hill,plateau and mountain the void-filling accuracy of high accuracy surface modelling(HASM)with those of the classical interpolation methods including TIN,SPLINE and IDW with and without auxiliary data sources of SRTM30 are compared.The results indicates that no matter whether SRTM30 is used,HASM is more accurate than TIN,SPLINE and IDW.Compared with the classical interpolation methods,the filling superio... |
