| Abstract: | 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. |
