这是用于个GIS中的最短路径的算法，通常的经典算法有无法自学习的功能，而此算法很好的解决了此问题-This is a GIS for the shortest path algorithm, usually classical algorithm is not self-learning function, This algorithm good solution of this problem

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
