摘要
多源数据匹配是数据转换、更新与融合的关键技术。随着GIS技术的发展以及地理信息空间数据不断增大,多源空间数据的匹配与融合成为目前GIS领域面临的重要问题。本文对多源道路网的匹配算法进行了研究,并在传统算法的基础上创建了一种可适用于多源道路网自动匹配的通用算法。该算法能够更加便捷和高效地利用道路间的拓扑特征与上下文信息关系,从而极大地提高了匹配运算的成功率和准确度。大量的数据测试表明该算法同时具有成功率高、准确度高以及通用性强等多项优点。
Spatial data matching technology is the key technology of data conversion,updating and integration.With the development of GIS technology and increasing of the geo-spatial data amount,the matching and integration of multi-source geo-spatial data become a major problem in GIS. Based on the investigation of various traditional matching algorithms,a generic road-network automatic matching algorithm between different datasets is proposed in this paper. This matching algorithm is able to make use of topologic information more conveniently and sufficiently,which allows a context-related topologic analysis,thus helps to improve the results of automatic data matching. The conducted experiments demonstrate that the proposed algorithm has very satisfying performance with respect to matching rate,matching accuracy,generic nature,and so on.
