An Improved Algorithm of TIN Construction and Convert into GRID

Xu Qing Ma Xudong Chang Ge Yang Li  
There isn't a very effective algorithm of construction irregular triangular network based on large contour data. After discussed the method of constructing Delaunay triangulation based on discrete points of large contour data, this article provides and realizes an improved algorithm of converting TIN into GRID. The last experiment illustrates correct and efficient of the algorithm.
