摘要
空间数据互操作和服务共享一直是开放式WebGIS追求的目标,用GML对空间数据进行统一编码,并设计针对GML文档存储的GML空间数据库达到空间数据的互操作目的,利用Web服务技术实现系统之间的互操作,通过XSLT技术把GML文档转换成SVG在客户端进行显示。系统从数据源到客户端显示都基于开放式标准进行,以此实现真正意义上的系统的完全开放。
In this regard Achieving spatial data interoperability and services sharing has always been a goal of open WebGIS. , we suggest that GML can be used for spatial data encoding, and in order to achieve data interoperability the documents of GML are stored in GML spatial database. The technique of Web services can be used to deal with the problems of function interoperability. Finally, the GML documents can be tranformed into SVG documents by XSLT, so the spatial data can be displayed on the screen. The system from data source to client display are all based on open standards specification, so a completely open system will be achieved.
