摘　　要：地图注记是描述地图要素的文本,在嵌入式地图绘制中,地图要素之间注记重叠问题直接影响到地图的绘制效果。该文基于一种网格编码算法设计了地图要素的动态注记方法,实现地图注记信息的自动避让。实验表明,该方法具有良好的注记效果,可以满足嵌入式系统实时性的要求。Map annotation is text to describe map elements,In Embedded mapping,Overlapping notes between map elements affect the rendering effect of the map directly.This paper designs a dynamic labeling method of map elements based on a grid coding algorithm,to realize automatic avoidance of map note information.The experimental results show that this method is good of effects and efficiency to meet the demand of real-time in Embedded system.
