摘　　要：针对目前多尺度地图要素点目标一致性检查方法效率低实用性不强的现状，本文提出一种基于属性模板匹配和几何相似性相结合的检查方法，即先通过多尺度地图点要素一致性属性匹配模板进行属性要素的快速粗匹配，在此基础上进一步进行几何匹配，根据制图综合规则，得出多尺度地图要素点目标一致性检查结果，实验结果表明，该方法具有效率高、速度快、可靠度高的优点，能够较好地满足多尺度地理信息生产和更新处理作业的需求。As the consistency checking method for multi - scales map features point object is low efficiency and poor practicability, a combined checking method based on attribute template matching and geometric similarity is proposed in this paper. First, features attributes are matched quickly and coarsely through consistency matching template multi - scales map point object. Then geometric matching is taken based on the previous step. Finally, the consistency check results of multi - scale map elements are obtained according to the cartographic generalization rules. The experiment results show that this method has the advantages of high efficiency, fast speed and higher liability, which can meet the requirements of multi - scale geographic information production and update operation.
