一种新的将mapinfo与sufer结合起来绘制等值线的方法的研究，结合了mapinfo和sufer各自的优点！-a new MapInfo will combine with sufer contour mapping methods of research, combination of MapInfo and sufer their respective advantages!

等值线的应用非常广泛，等值线的绘制主要有两种，基于不规则三角网的绘制最好,Isogram a very wide range of applications, contour drawing, there are two main, based on triangulated irregular network of the best mapping

自动绘制等值线的方法从技术方向上看可以分为两大类,插值和曲线拟合.其中曲线拟合总的来说效果不如插值算法经典和应用广泛,效果也较逊色.这里着重介绍插值算法.-Automatic drawing method isogram direction from a technical point of view can be divided into two categories, interpolation and curve fitting. In which the effect of curve
