多源异构空间数据集成模型的研究

Research on model of multi-source heterogeneous spatial data integration

本文就目前空间数据集成的两种主流模式,在论证了各模式的优缺点的基础上,得出了用GML作为地理空间数据转换及传输的标准是切实可行、具有应用前景的方案。从而提出了基于GML的多源异构空间数据集成的模型,并探讨了基于这一模型实现空间数据共享的若干问题。

This paper introduced the two current main spatial data integration models. After analyzing the advantages and disadvantages of each model, it concluded that the use of GML as geospatial data conversion and transmission standard would be feasible and promising programs. Thus, the model of multi-source heterogeneous spatial data integration based on GML was proposed, and related problems of sharing the spatial data were discussed based on this model.
