摘要
本文在分析了W eb服务体系结构和OGC相关规范的基础上,提出了空间地理信息网络服务集成框架。框架由空间地理信息服务(提供者)、空间地理信息服务注册处(中介)和客户端(请求者)组成。并利用ESR I的空间地理信息网络服务雏形-ArcW eb,成功构建了一个简单的G IS应用。最后提出了要真正实现成熟的标准框架,还需要解决服务的标准化、空间数据传输以及地图数据显示等问题。
Based on the analysis of Web service architecture and some implementation specifications related to OGC,this paper proposes an integrated framework for geo-spatial web services which consists of Geo-spatial servers(Service Provider),Geo-spatial broker(Service Broker),and web-based clients(Service Requestor).Then,the authors use ESRI's Web services-ArcWeb to establish a GIS application system successfully.At last,they put forward some problems in order to realize the mature framework,such as how to make geo-spatial web services conform to the web services architecture,how to transport geo-spatial data and how to show map data(especially the vector-typed data) and so on.
