| Abstract: | In order to discuss the application of digital terrain models, DTM elevation interpolation theory theoretical research methods are combined with the engineering case study of calculations. Study shows that high order polynomial interpolation, linear interpolation, surface overlap interpolation and least - multiplication interpolation differ- ence algorithm can be used to complete the DTM model interpolation calculation. It is very effective to apply the algorithm to engineering planning design, area and volume calculations, route~ contrast and planning optimization. |
