摘　　要：地理信息系统的迅速发展和广泛应用积累了大量数据资源 ,它们存储的数据格式互不相同 ,这导致了空间数据多源性的产生 ,给数据综合利用和数据共享带来不便。本文探讨了多源空间数据的现状及类型 ,指出多源空间数据集成的迫切性并展望了多源数据集成的发展方向。GIS has accumulated a number of data resource in quick development and extensive application, Its data format stored is different from each other,so the multisource spatialdata is come out and inconvenience is appeared in synthetical exploit and sharing. In this paper the multisource spatialdata present condition and type is studied and the urgency and the developmental direction of the integration module of multisource spatialdata is emphasized and expected.
