基于地理本体的空间数据组织方法与应用

摘要

The Geo-ontology describes different levels and applications of the detailed connotation and level relations about geography spatial concept in the domain of geography information science.This article discusses the spatial data organization method based on Geo-ontology,forms a mapping connection between the geography entity and the geo-ontology while carrying on the organization and the expression of the Geo-ontology system cases by object-oriented method.So as to satisfy the compatible spatial data management and the semantic sharing request as well as to solve the data organization and sharing difficulty caused by semantics isomerism in different application domains.Taking the urban road data management as an example,the article talks about the designation of an integrated urban road data organization,and it provides the realization of the urban road intellectualization service system with rationales.%地理本体描述了地理信息科学领域内不同层次和不同应用方向上的地理空间概念的详细内涵和层次关系。研究和探讨了基于地理本体的空间数据组织方法,将地理实体与地理本体建立映射关联,把地理本体系统中的实例用面向对象的方法进行组织和表达,从而满足兼容空间数据管理和语义共享要求,解决语义异构导致的不同应用领域间数据组织与共享的困难。并以城市道路数据管理为例,设计了一体化的城市道路数据组织模式,为城市道路智能化服务系统的实现提供了理论基础。
