| Abstract: | According to the peculiarity of establishing DEM by using the plane interpolation,a method has been put forward to treat the special topopraphy such as the mountain rid-ge line, the mountain vally line, the steep slope and the case of interpolating forbiddenarea, so as to improve the modelling accuracy and the interpolating accuracy. Testsindicate that this method is implementable and effective. |
