摘要
应用杨赤中滤波推估法,将地形碎部点高程观测值经插值转换为格网DEM数据,并利用VB和MapInfo来实现其立体等高线的绘制功能。在此基础上,阐述其地形剖面分析功能的设计与实现。最后通过实验比较,验证了基于杨赤中滤波推估法的地形剖面分析能取得较好的效果。
The broken terrain elevation observed values by interpolation was converted to grid DEM data based on Yang Chek filtering estimation. With VB and MapInfo as tool, the three-dimensional contour mapping can be obtained. On this basis, the design and implementation of terrain profile analysis is realized. Finally, after experimental comparison, it shows that this method is effective.
