Towards geospatial interoperability based on geo-service and geo-ontology
نویسنده
چکیده
The complex and proprietary nature of geospatial data makes them almost non-sharable among large user community. GIS interoperability is necessary for realizing a successful spatial data infrastructure. With the advancements of web service technology, GIS interoperability has made a paradigm shift – from monolithic GIS providers to distributed geospatial services. The applicability of web service standards in geospatial domain has been studied in this paper. The application of ontology in various information systems and its applicability in geospatial domain has brought a new direction in interoperability, namely, semantic geospatial interoperability. The context-based matching of geospatial services requires the concepts of the domain to be structured properly and ontology is an ideal tool for that. In this paper several issues relating GIS interoperability has been identified and service based geospatial integration with the help of ontologybased knowledge of the domain has been proposed.

متن کاملInteroperability on the Web: the Case of 3d Geo-data
Geographic information (also called geo-information, spatial information or geospatial information) plays an increasingly important role in our society. Location Based Services, applications for urban planning, disaster management systems rely on geo-data and in many cases up-to-date geo-information is crucial, e.g. in disaster response systems. In this paper we focus on a special kind of geo-i...
متن کاملOntology Matching for Geospatial Domain
Geospatial information is collected from different sources with disparate terminologies resulting in highly heterogeneous information thus making its compilation and retrieval difficult. Harmonization of these heterogeneities is needed for interoperability and seamless access to the information sources by providing a common platform for facilitating information exchange. This can be achieved by...
