本文通过分析遥感分类图栅格像元之间的关系，快速自动地提取矢量数据点及其连接信息，

进而利用连接信息快速生成弧段，由弧段自动组建多边形并建立完整的拓扑关系。实验表明，该方法是一种由遥

感分类图自动转换成GIS通用数据的高效方案。

关键-In this paper, through the analysis of remote sensing classification raster pixel map the relationship between the Express automatically extracted vector data point and its connecting information, which is linked with the rapid generation of information arc, automatic arc formed by the polygon and the establishment of a complete topological relations. Experiments show that the method is a remote sensing classification map automatically converted to common data and efficient GIS program. Key
