摘要
通过建立栅格数据的网格关联规则,构造出一种能够同时对等值线和分级面域轮廓线内插追踪的算法模型,实现了用网格法绘制等值线图和分类图的程序设计。模型算法简单、结构合理、易于编程实现,具有运算效率高、结果稳定、容错性强、精度高、图形效果好等特点。
In this paper. An algorithm modeI, which can interpolate and trace contour and graded area field contour at the same time, is constructed by creating the grids related regulation of raster data. Programming of drawing isoline map and classified map with grids algorithm is realised. Model makes a feature of simple algorithm. rational structure.easy programe. high-efficient operation, stable result, strong anti-eerror. high precision and good graphic effect.Kevwords:Grides related regulation. Related ordinal numer. Related factor, Contour.
