Geo-Object Catalogs to Enable Geographic Databases Interoperability
: This paper introduces the concept of Ontology based Geo-Object Catalog (OGOC). An OGOC acts as a focal point for a federation of independent geoobject sources, providing consolidation services for the geo-objects represented in several, as well as access services to query geo-objects and metadata. To accomplish this task, an OGOC stores a reference ontology, which also includes reference geo-object instances, and ontologies representing the conceptual schemas of the data sources. The paper also considers a framework for the creation of personalized OGOCs. Key words: ontology, catalog, database interoperability.
