摘要
从地图代数理论符号概念出发,介绍了绘制符号两种主要方法的特点和栅格符号库的设计思想,重点给出了点状符号库和线状符号库数据结构设计方案。该结构方案简单实用,符号美观精细,是符号化代数方法的基础。
In this paper,starting from the symbol's conception in the cartographic algebra theory,the characters of two types methods on symbol's drawing and the idea of raster symbol base are introduced.The data structure design of the dot-symbol and line-symbol base is given emphatically.This scheme is simple and practical,it is the foundation of the algebraic method on symbolising.
