Abstract: Isograms map plays one relative important role in the application of science research，oil geologic exploration etc.This paper puts forward one stack based border-scanning algorithm for generating filling isograms map.Taking the advantage of stack’s FILO（first in last out） characteristic，this method can help get isolines’ topological relations by sorting all the isoclines’ and filling-border’s feature points，then closed connected regions can be traced.It also puts forward one double-depth algorithm for color-filling，which is easier for understanding and realization of filling vector graphs rapidly than other ways.

摘要： 等值线图在科学研究、石油地质勘探等应用中具有较重要的应用。对于生成填充的等值线图，提出了一种基于堆栈式边界扫描方法，该方法通过将填充边界特征点和等值线特征点进行统一排序，利用堆栈的先进后出的特性，得到等值线之间的拓扑关系，进而追踪出闭合连通区域；对于颜色充填，提出了一种双深度值填充方法。与其他方法相比，该方法较容易理解与实现，对矢量化图件能快速填充。
