摘要
空间数据共享和互操作是GIS领域迫切需要解决的重要问题,文中基于OGC规范,探讨了空间数据访问中间件的实现策略,并给出相应的实现模型,屏蔽多源空间数据的异构性和复杂性,实现分布式异构环境下的共享和互操作。
Spatial data sharing and interoperation are becoming more and more important in GIS. Based on OGC specifications, this paper discussed the implementation strategy for spatial data accessing middleware, corresponding implementation model. This middleware can realize spatial data sharing and interoperation under heterogeneous circumstances by hiding the heterogeneity and complexity of multi-sources spatial data.
