在地图符号中公路类符号的绘制具有其特殊性,必须进行特殊处理才能正确显示。文中首先介绍了常见的两种处理方法,并分析了其存在的问题;然后针对地图出版的要求,在全数字地图出版系统中,利用STL标准模板库技术,对公路要素进行批处理绘制,很好地解决了公路类符号的绘制问题。

In the map symbolization processing the displaying of the highroad has its particularity. Only through especial managing can it be displayed correctly. This paper introduces two familiar ways which can deal with this problem and analyzes their shortages. Then aiming at the demand of map publish we solve it successfully by the way which take the highway elements into batch processing using STL.
