摘要
多源异构的空间数据成为空间信息共享的瓶颈,在网络环境下如何实现多源异构空间数据的集成,成为当前GIS(地理信息系统)发展的一个热点和难点问题。提出了一个基于GML(地理标记语言)的多源异构空间数据集成模型,解决了多源异构空间数据向GML文档的转换,GML与空间数据库服务器的交互以及GML向SVG(可缩放矢量图形)的转换,并使用WebService技术,在Microsoft.NET平台上设计实现了多源异构空间数据集成系统,从而实现了基于GML的空间数据集成和基于SVG的空间数据可视化。
Multi-source heterogeneous spatial data has been the obstacle of the spatial information sharing. Hence, how to realize the integration of multi-source heterogeneous spatial data becomes the focus and difficulty of the development of GIS （geographic information system） at present. The model of multi-source heterogeneous spatial data integration based on GML （geography markup language） is proposed, the conversion fi＇om multi-source heterogeneous spatial data to GML, fi＇om GML to SVG （scalble vector graphics）, the interaction between GML and spatial database server are provided. A system of multi-source heterogeneous spatial data integration is designed and realized on the Microsoft. NET platform with in webservice, and spatial data integration based on GML and visual of spatial data based on SVG are realized.
