Geoprocessing platform based on OGC-compliant spatial data services
基于OGC数据服务的空间信息处理服务平台

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.
