三维的

Some questions in digital elevation model were discussed detailedly, such as the obtaining of data points, the fast searching of reference points, the interpolation algorithm of quadric surface, the abnormal data eliminating, and so on. And this paper has realized the 3D vectorization of 2D terrain maps, the 3D display and edit of DEM data with the help of secondary development of CAD.
