基于同属性等值区域追踪的填充算法

Based on Equivalence Region with Same Attribute Tracing for filling Algorithm

为了对等值线图中不同区域进行不同颜色的填充,更加明显地体现出数据变化的趋势,可以利用等值线边界点序列找出各个属性的所有等值区,根据各个属性等值区之间的关系,得到实际的填充区域,然后把一种属性对应一个颜色,用一种颜色来填充对应的实际区域,此算法在项目《地质资料解释系统》中得到了实际的应用,效果理想。

Aim： To fill different region with different color in isogram graphs and then to show more clearly the tendency of changing data. Methods： Searching for every equivalence region with same attribute in use of border points sequence in isogram, and getting the actual filling region by the relation of each equivalence region. Then an attribe has a color, the color is used to fill the corresponding region. Conclusion： This algorithm has been used for the project to explain geology information system about isograms and the effect is satisfied.
