| Description | Emergency management (EM) is a cross border domain which covers a large number of human activities. Successful decision making largely depends on having right information in the right moment. There exist large amount of geodata with high potential of use in the field of EM. Besides basic topographic datasets there are thematic data that reflect specific conceptualization of their proprietor. Paper address semantic issues that concern survey of relevancy and roles of geodata in different context-aware scenarios within the use case transport of dangerous goods. Ontology principles are implemented to support context visualization and thus improve emergency response at various phases: the monitoring stage and the incident stage. Two main questions are addressed: 1. What is the role, existing geodata can play in EM? 2. What is the role of geodata in the specific emergency situation? It is obvious that application designer on one hand should have an idea of what task is being solved and what information is relevant, on the other there should exists detailed knowledge about data semantics and the solution of the task must be adapted to available data. Semantic issues of defining both data- and application- ontology are discussed and mapping between their concepts via ad-hod domain ontology is outlined. Adapting ontology principles can improve not only geodata integration process, but also visualization and thus enhance efficiency of decision making in the field of EM. |
