A Study of Spatial Information Sharing Model Based on Geological Hazard Domain Ontology

We contrapose related standards such as industry professional standard, geological hazard information processing standard and expert knowledge. We introduce the idea of geo-hazard ontology geo-hazard domain ontology. Ontology is used to carry out semantic sharing model to improve interoperability capacity of geological hazard information. Geological hazard ontology is applied to realize data and application aggregation. We proposed heterogeneous multi-source information integration approach to geological-disaster, achieving a multi-source, muti-scale, heterogeneous integration of geological disaster data, description, organization and management, And then we designed and elaborated the geo-shared service framework and Wenchuan geo-disaster evaluation and application system that is adapted to Wenchuan zone. In order to resolve the problem of decision making when single hazard or group hazards occur, the problem of effective communication and information sharing between the horizontal departments demonstrates important research significance.
