| 摘 要： | 数字高程模型(DEM)能有效描述地形结构,可视化技术是当今表达和分析复杂数据的有力工具。应用杨赤中插值法,将地形碎部点高程观测值看作一种包含规律性变化和随机性变化的复合变量,求其二项系数加权游动平均,建立估值数学模型,划分格网,求得各格网点高程估值。并阐述利用网格法来实现、分析和显示DEM数据的可视化原理和实例。

| Abstract: | The digital elevation model(DEM) can effectively describe the terrain structure.Visualization technology is the contemporary powerful tool for the expression and analysis of complex data.Using Yang Chek Interpolation method,details of terrain elevation measurements are considered as the composite variables including regular and random changes,the binomial coefficient moving weighted average are obtained,the valuation mathematical model are established,the grid are partitioned,and the elevation valuation of each lattice point are obtained.It also explained the visualization principles and examples to realize,analyze and display DEM data using grid method. |
