Abstract

Abstract: Aiming at deficiency of building conceptual model of spatial database with E-R model, the ontological ideology and methodology are introduced into the geographic information domain. The exact meaning and its formal represented language of geographic ontology are discussed. Characteristics of spatial E-R model are clarified and relationship between geographic ontology and spatial E-R model is analyzed. The thinking of designing spatial E-R model based on geographic ontology as semantic foundation is presented. And a method of establishing conceptual model of spatial database by designing spatial E-R model from geographic ontology is introduced with an example about irrigation ontology represented by expanded OWL.

Key words: Geographic ontology, Spatial E-R model, OWL, Spatial database

摘要： 针对用E-R模型建立空间数据库概念模型存在的不足之处，将本体论的思想和方法引入到地理信息领域。讨论了地理本体的意义及其表达语言。阐述了空间E-R模型的特点，分析了地理本体和空间E-R模型之间的关系。提出了以地理本体为语义基础设计空间ER模型的思想，并用扩展OWL表示的灌溉本体为例，介绍了从地理本体出发，设计空间E-R模型来建立空间数据库概念模型的方法。

关键词: 地理本体, 空间E-R模型, OWL, 空间数据库
