| 摘 要： | 显示电子地图时,某些同类的线要素相交时不能用简单的压盖关系来解决,必须经过特殊处理才能达到显示要求,传统的办法是采用线蒙片来解决,文中提出一种符号分解绘制法,在不需要线蒙片的情况下,成功解决了同类线要素相交的显示问题,不但可以减少作业员的工作量,而且可以提高电子地图显示的速度。

| Abstract: | When a map is drawn,if some congener linear elements intersect,it can't be settled by simple cover relation but by special treating.The traditional way adopts linear cover.It uses the method of symbol decompose drawing.This method solves the displaying problem of congener linear element intersection without linear cover.It not only decreases workers' workload but also increases the painting speed of map. |
