摘　　要：该文讨论了地名注记自动配置涉及的关键问题,包括:注记参数、压盖地物的优先级、注记与地图符号的关系、注记与地物的压盖检测及注记大小的自动确定等,并给出了解决方法。提出了基于栅格数据的线状地物的地名注记自动配置算法,介绍了笔者开发的地名注记软件AutoLabel。Name automated placement involved in many factors, such as name parameters, the precedence level of features, the relation between name and symbols, the overlap checking of name and feature and automated decision of name size. The parameters of name, symbols and feature precedence level can be stored in tables of relation database respectively. There are proposed two methods of overlap checking, one is real overlap of names, another is virtual overlap of names in this paper. For the compute efficiency of raster data, both methods are based on the raster data. We also present the algorithm for name placement of line feature based on raster data and the flow charts of algorithms. Finally we introduce a software of name automated placement 'AutoLabel'.
