逻辑分类体系下的地图符号库底层开发

Low level development of map symbol library under logical classification system

当前的地图符号的制作多是利用已有的符号系统或二次开发,这种方法绘制的符号拓展性有限,因此进行地图符号库的底层开发十分重要。本文借助于GDI+设计了逻辑分类体系下的地图符号库底层开发方案,包括地图符号分类与属性设计、符号库底层类设计和符号库建设,长远看来,由GDI+构建的底层符号库系统具有很强的实用性和扩展性。

Currently,map symbols are made usually by using existing symbol library system or secondary development,leading to the symbols with poor scalability,so it is important to make low level programming of symbol library.With the GDI＋,the paper designed a low level programming scheme of symbol library under a logical classification system,which includes map symbol classification and attributes design,low level class design of symbol library and symbol library construction.In the long run,it would have strong practicality and scalability of the low level symbol library system by GDI＋.
