| 摘 要： | 当前由等高线数据生成DEM数据的方法大部分都存在算法复杂,实现困难等特点。文章描述了一种通过矢量等高线生成DEM数据的简易方法。通过将等高线网格化然后再进一步进行横向和纵向的插值,生成DEM数据。该方法具有简单易行,适用于精度要求不高的场合。而且对硬件的要求也不高。生成的DEM数据很容易转换成三维模型。

| Abstract: | The methods of generating DEM data based on contour images are too complex to realize them at present.This article display a simple method of generating DEM data based on contour images.Contour images converted into grid be filled with interpolation in two direction to generate DEM data.The method is simple and realize easily.It suitable for low accuracy requirement,low configurations of computer hardware.And,the DEM data can converted to 3D model easily. |
