Abstract

To achieve accurate results when matching geographic ontologies, it is important to have clear what has to be compared, and just then start comparing them. In this paper we define a geographic ontology reference model and, from it, the set of heterogeneities that may occur when comparing two geographic ontologies is elaborated, at both the concept and instance-level. Based on the heterogeneities set we then present the iG-Match, which consists in a software architecture that implements a methodology to perform geographic ontology matching, using some metrics specially developed for the geographic domain.
