为解决空间数据分布异构的问题,根据地理本体与地理网格的特点,提出一种将地理本体映射到地理网格的新方法,并用该方法构造一种基于本体的空间信息网格系统。该系统通过描述空间信息的语义内涵的本体系统对空间信息数据进行索引和组织,并以地理网格为其存储和管理单元,可以有效地解决在广域网络环境下的空间信息资源整合的问题,促进空间信息共享与利用的研究。
For integrating spatial information systems, the geographic ontology and geographic grid are used, and the spatial information system grid (SISG) can be built by using geographic ontology and grid. The geographic ontology could be used to describe the meaning of the geographic objects, and geographic grid can be used to manage, index and storage the spatial information. SIMG could integrate the spatial information system and improve the sharing and utilizing of spatial information.
