Integration of Geographic Information Services for Disaster Management

In recent years the OpenGIS technology standards have been developed by the Open Geospatial Consortium (OGC), which provide the essential basis for syntactic interoperability of geographic information services, also gives an opportunity for data interoperability, data integration and data sharing between different emergency management agencies. However finding suitable services and visualization of geospatial information served over the Internet for decision makers is still a crucial task. Therefore this paper proposes a service-integration architecture to facilitate the discovery of geospatial information services (GI services), and provide a friendly user-interface for visualization of OGC-compliant services. Based on the proposed architecture, a prototype system has been developed to support catalogue service for information sources related to disaster management, including GI services. And OpenLayers, an open source javascript library, is used to access to GI services. The paper concludes with a discussion of the problems encountered and a brief view of our future work. * Corresponding author: G. W. Lan, email: [email protected]
