In this paper we proposed architecture, based on modified hybrid ontology approach and semantic mediation, for solving the problems of semantic heterogeneity. Process of semantic mediation is based on ontologies that provide abstract description of the content of information sources. It also uses ontologies to provide semantic consistency and geodata exchange with terminology translation. Proposed architecture provides means for building intelligent systems that can integrate a number of different information sources.
