Geospatial Data Integration with Semantic Web Services: The eMerges Approach
Advanced Information and Knowledge ProcessingThe Geospatial Web(2007)
摘要
Geographic space still lacks the semantics allowing a unified view of spatial data. Indeed, as a unique but all encompassing
domain, it presents specificities that geospatial applications are still unable to handle. Moreover, to be useful, new spatial
applications need to match human cognitive abilities of spatial representation and reasoning. In this context, eMerges, an
approach to geospatial data integration based on Semantic Web Services (SWS), allows the unified representation and manipulation
of heterogeneous spatial data sources. eMerges provides this integration by mediating legacy spatial data sources to high-level
spatial ontologies through SWS and by presenting for each object context dependent affordances. This generic approach is applied
here in the context of an emergency management use case developed in collaboration with emergency planners of public agencies.
