摘要
针对实际工作中内插等高线这一问题,分析了内插等高线算法的基本原理以及实际绘图时可能遇到的几种特殊情况,给出了用ObjectARX语言实现该算法的程序,提出了一些需要注意的问题。该算法及程序可以解决大部分地形图等高线的内插问题,在实际工作中具有较高的实用价值。
In the light of interpolation counter in mapping, we analyze basic algorithm of interpolation and some special problems arose in operation. After giving the flow chart of objectARX, we put forward some problems which deserve extra attention. The algorithm and program can resolve most of topography interpolation problems. It is worth for surveyors to use in practice.
