| 摘 要： | 为了解决传统地图等高线、天气图等值线手工分析的缺点,而以计算机自动分析作替代。通过考察插值、拟合几种数学方法,提出如何应用三次B样条函数,处理格点数据,寻找等值控制点,进行曲线拟合,这一方法具有客观化程度高、分析速度快且线条光滑等特点。

| Abstract: | In the article a mathematical method, Thrice B Spline Function, is applied to process matrix data and search the control dot of equivalence, then accomplish curve simulating base on the coordinate of control dot. This method is very effective in automatically computer analyzing - and -drawing map contour and weather map isobars. |
