同名实体几何匹配作为空间数据整合与更新的关键技术,其目的是建立多源数据库之间地理实体的联系,实现对多源数据的综合利用。本文研究了同名实体匹配的策略与技术流程,提出了一种多尺度道路网几何匹配算法与矢量一影像匹配算法,并实验证明了上述方法的有效性。
As the key technique of the spatial data integration and updating, spatial data matching aims to establish the relationship of the geographic entities from multi - source databases and finally realize the comprehensive utilization of the multi - source data. The paper studies the strategy and technological flow of identical entity matching and presents the muhiscale road network geometric matching algorithm and vector - image matching algorithm. The validity of the methods is tested by the experiment.
