| Abstract: | An interpolation algorithm of DEM is described based on vectorized contour lines and the visible technology of terrain surface production by DEM.In the process of creating digital elevation model,a new method is proposed.It utilizes the structural features of elevation contour images.A rapidly search method in searching contour lines is also given out.The algorithm is used in overhead electrical transmission line design system which shows good performance on both speed and accuracy. |
