GEOGRAPHICAL SEMANTIC REPRESENTATION FOR COLLABORATIVE EMERGENCY SERVICES
Geographical semantic representation, which aims at enhancing geospatial data model and facilitating information sharing and exchange, has been a hot topic in the realm of geographic information science. The research summarized here is to advance a geographical semantic representation framework to support geo-collaboration, focusing on how to take full advantage of Ontology and Web Services technologies to overcome the flaws of current WebGIS in the distributed cooperative computing model and application model, and make it better to serve collaborative GIS applications, such as collaborative emergency services. We considered a simplified evacuation scenario of toxic gas dispersion, following the proposed solution, the orchestration of application services based on semantics was conducted and illuminated.
