Ontologies are put forward to resolve the problem of information integration and heterogeneous knowledge sharing. Aiming at the issue of data redundancy and inefficient sharing, we propose a data sharing framework of microscopic traffic simulation and GIS based on ontology driven. The building process of requirement, analysis, design and implementation of the microscopic traffic simulation ontology...
This paper describes the design and implementation of a geographical knowledge-informed digital gazetteer service, KIDGS. It is a standard web service that provides unified XML-based access interfaces for various applications. At present, many digital gazetteer systems are implemented directly based on relational databases. In other words, place name entries are managed by data tables. However, several...
Sensor observation service (SOS) is a Web service specification defined by the Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE) group in order to standardize the way sensors and sensor data are discovered and accessed on the Web. This standard goes a long way in providing interoperability between repositories of heterogeneous sensor data and applications that use this data. Many of these...
The semantic Web enables an automated, ontology based information aggregation mechanism. In geographic domain, automatic aggregation is a particularly important task in light of the over-abundance of data formats and types. Because the formats and types are not necessarily uniform or adhere to a particular information structure, aggregating geospatial data with differing formats is a challenging task...
