摘要
WFS是OGC空间数据互操作的主要规范之一。研究了最新的地理数据格式GeoJSON,结合GML分析了两种数据表达的差异,指出GeoJSON在网络数据传输上的优势。从标准的WFS出发,提出和设计了一个基于GeoJSON的地理数据传输格式的WFS实现框架。最后通过浏览器客户端调用WFS服务接口,验证了所提出的WFS体系架构,为WFS互操作规范的实现开辟了另一条行之有效的途径。
WFS is one of important OGC specifications in spatial data interoperability.After researching the latest geographic data format GeoJSON,the advantage of its data transmission on the network was pointed out based on the analysis of data expression differences between GML and GeoJSON.Then WFS realization architecture was proposed and designed,which use GeoJSON as spatial data transmission.In the end,WFS service interface was called by the browser client to validate the WFS architecture.It opens up another effective way to the realization of the WFS interoperability specification.
