Research of ontology-based Web spatial decision support system
基于本体的网络空间决策支持系统研究*

To build different SDSS (spatial decision support system) to support different geospatial decisions. Among these SDSS, GIS data and models are usually used repeatedly. Thus, this paper proposed a ontology-oriented geospatial decision support system for discovering, efficiently using, and automatically executing GIS data and analysis resource on Internet. By the ontology-based system, it not only presented an ontology-based and Web GIS services-based spatial decision support service, but also provided a flexible architecture to solve geospatial semantic impediments which can be applied to different domain.
