平面插值法构建DEM时特殊地形的处理

On The Treatment of Special Topography in Establishing DEM

    摘要
  • 摘要: 本文根据平面插值法构建DEM的特点,提出了一套处理插值禁域、山脊线、山谷线以及陡坎等特殊地形的方法,以期提高建模与插值的精度。试验证明该方法是行之有效的。

     

    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 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.
