摘　　要：基于WinCE嵌入式系统,根据地图注记的主要原则,按点、线、面3种要素分别介绍其注记自动配置方案.重点介绍了点状要素和线要素的注记自动配置.在地图自动注记的研究中,线状要素由于其形状复杂、灵活性大,难度较大,在注记自动研究问题中占有较大的比重.探讨了线状要素自动注记的问题,提出了一种解决线状要素自动注记问题的思路和方法.对于面状要素的注记,为了节省计算量,可按点状要素来注记.Based on embedded system-WinCE,this paper divides the map labeling into point, line and area labeling according to some main principles of map labeling.It givs more emphasis on point labeling and line labeling.In the study of adding annotation to the map automatically,the problem of linear feature poses the important position because of its complexities and difficulty.Focused on the problem of adding annotation to the map especially for the linear feature automatically, a method that is proved to have a fairy permanence and a good results is presented in the paper.And for area labeling,it can be simplified into point labeling for saving calculation.
