基于OGC数据服务的空间信息处理服务平台

摘要

This paper proposed a solution to bridge the gap between the growing open geospatial data and geoprocessing services. The solution wrapped the existing GIS functionalities into geoprocessing services following OGC-WPS standard. Compared to the mainstream GIS systems, instead of using spatial database, the solution used the OGC compliant services such as WFS, WMS and WCS as the data layer. Therefore, it made the open spatial data convenient for users to use in geoprocessing services directly. Finally, it implemented a prototype system and carried experiments, which used the online open spatial data services. The results show that the solution is applicable and of great help for geospatial data sharing and interoperability.%设计了基于OGC数据服务的空间信息处理服务平台.平台封装了现有的开源GIS软件包含的丰富的空间信息处理功能,对用户提供在线的OGC-WPS服务.较传统处理平台不同的是,平台以符合OWS协议框架的空间数据服务(WFS、WMS和WCS)作为空间数据层,极大方便了开放地理信息在用户之间的共享和互操作.最后,开发了原型系统并利用互联网上的开放地理信息服务作为数据源进行测试,证明了平台及其方案的可行性和实用性.
