Methodology for geospatial data source discovery in ontology-driven geo-information integration architectures

Our methodology simplifies geospatial data discovery and can be easily implemented because it uses ontological components of the underlying architectures in their original form. The methodology we describe in this paper will be discussed in the context of similar prominent solutions. Also, this paper will present a prototype which will demonstrate the applicability of the proposed methodology. The implemented prototype is a stand-alone desktop application, which uses two resources as input: userdefined geo-information description and (domain/local) ontologies developed using Web Ontology Language (OWL). We will provide an overview of benefits over approaches that have been previously used for geospatial data discovery and offer guidelines for future improvement and development.
