摘要
E-R model plays an important role in the field of modeling the spatial database. Improving the quality of the E-R model is a very challenging task. In this paper, we introduce the ontological ideology and methodology into the geographic information area. The characteristics of spatial E-R model and the relationship between geographic ontology and spatial E-R model are analyzed. Furthermore, we propose the idea of designing the spatial E-R model based on the Geo-Ontology and give an example about irrigation ontology with Web Ontology Language. © 2008 IEEE.
