On The Treatment of Special Topography in Establishing DEM

  • 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 ridge line,the mountain vally line,the steep slope and the case of interpolating forbidden area,so as to improve the modelling accuracy and the interpolating accuracy.Tests indicate that this method is implementable and effective.
