| 摘 要： | 针对地图制图数据库更新中多源数据匹配问题,通过提取线目标中的特征点,建立一种基于空间位置和拓扑关系的匹配模型,对特征点进行相似性匹配。实验证明该模型匹配效果良好,基本满足数据更新中图形纠正的需要。

| Abstract: | For the matching cases of multi-source data on mapping data updating,by extracting the feature points from the line objects,a model of similarity matching is established based on space-based position and topology.Experimental results show that the model matches basely well with the needs of the graphic correction in the data updating. |

| Keywords: | mapping spatial location topology feature points similarity matching |
