基于GML和SVG的空间数据可视化接口设计

Design of spatial data visualization interface based on GML and SVG

针对如何实现网络环境中GML数据的客户端显示,编写了GML文档到SVG文档的通用转换样式表,并借助Visual Studio.NET平台,设计了空间数据可视化接口,经实践验证,该接口可快速、有效地实现空间信息的可视化,对于基于GML的多源异构空间数据集成系统的开发有较好的借鉴价值。

In order to resolve the visualization of GML document in client, the core teehnolygies of GML and SVG, including how to recognize, manage and express spatial data were analyzed. Based on that, the common XSLT between GML and SVG was designed. Then, with the help of the platform of visual studio . NET,the interface for spatial data visualization was recognized. It was proved that the spatial data can be drawn effectively and speedly with the interface. Addtionally, it would provide perfect reference value for the system which integrats variable source and structure spatial data based on GML.
