Interoperability for geospatial analysis: a semantics and ontology-based approach

摘要: Information extraction and integration from heterogeneous, autonomous data resources are major requirements for many spatial applications. Geospatial analysis scientific discovery involves identification of relevant information resources, fusion requisite subsets the information, application analytical techniques visualization results in an appropriate form. The motivating domain underlying this research is marine environmental management, although principles discussed apply to a wide range disciplines. paper focuses on sources, exploration interactive analysis. A knowledge base used capture semantics spatial, temporal thematic dimensions at level, context-aware framework exploited meet varied distributed user community with differing objectives.
