Study on GML-based Integrative Model for Multi-sources Spatial-data
基于GML的多源空间数据集成模型研究

Basis of the integration mode of data interoperability, this paper adopts the idea of designing mode and GML(Geography Markup Language), and designs an integration mode of spatial data. The principles are illustrated in details. Then data from several systems are integrated as examples. This method proves to be a practical way in spatial data integration.
