【摘要】 地理空间数据集成是地理信息科学研究的一个重要内容。本文引入地理本体的思想,提出了基于地理本体的空间数据的组织方法,构建了基于本体的空间数据集成框架。本文运用上述方法,通过对烟草地理本体的建模,建立了客观反映烟草地理实体各个层次体系的概念模型,再根据烟草概念和已有地理数据集之间的映射关系,构建基于地理本体的烟草空间数据库,从而实现数字烟草多源空间数据的一体化集成与管理,以及数字烟草空间信息的共享与互操作,达到了很好的应用效果。更多还原

【Abstract】 The geographic data set integration is an important content of geography information science researches.The traditional spatial data integration ways cannot effectively integrate the semantics of the different geography spatial data,which has brought the ga Pof information acquisition and information understanding for integrated data sharing and the use.An ontology is an explicit specification of conceptualization.It may effectively integrate the geography spatial data and its semantics,and overcome the flaw which the traditional spatial data integration method is unable to overcome.This article based on the ontology theory,put forward the organization method and the applied research around domestic and foreign geography information academic improved ontology-driven geographic data set integration frame,and carried on the confirmation explanation by a digital tobacco example.更多还原
