基于MapX数字高程模型的实现

Implementation of DEM Based on MapX

为了建立保持一定精度的数字高程模型,在分析了现有利用等高线生成数字高程模型的插值算法的基础上,提出了一种基于MapX软件的改进的补点插值算法,并进行了计算机仿真.仿真结果表明该方法较之其他方法更快速、有效,能对地形的高度特征进行较好的描述.

On the basis of analyzing the present interpolation algorithm using the identical elevation lines to establish DEM, an improved plot-patched interpolation algorithm was presented to establish DEM based on MapX. By simulation it shows that the proposed method is faster and more effective than the other ones, by which the altitude feature of the landform can be well described.
