Research on Integration of Multi-source Spatial Data
多源空间数据集成的技术难点分析和解决策略

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.
