多源空间数据集成的技术难点分析和解决策略

Research on Integration of Multi-source Spatial Data

目前多源空间数据集成的模式有数据格式转换、数据互操作和直接数据访问。在分析了这几种模式的原理及不足之后,着重讨论了多源空间数据无缝集成(SIMS)模式,通用空间数据引擎(USDE)模式和数据中间件(M iddleware)模式在多源空间数据集成中的应用。

At present, the modes of the integration of multi-source spatial data are data format exchange, data interoperation, and directly data access. In this paper, the author analyzes the principle and the shortage of such modes. Then the seamless integration of multi-source spatial data, universal spatial data engine, and middleware technology are emphasized.
