Standardised geo–sensor webs and web–based geo–processing for near real–time situational awareness in emergency management
Up–to–date, accurate, and reliable information is fundamental for time–critical decision support and sustainable emergency management. In this paper, we show how standardised geo–sensor webs, in combination with web–based geo–processing, can enhance efficiency in emergency response and management, demonstrated in the field of radiation safety. We focus on end user and information requirements and show how 'live' spatial–temporal analysis results of near real–time and mobile radioactive radiation sensor measurements can enhance the situational awareness of rescue forces for near real–time decision support. We validated our approach technically and methodologically through a radiation safety exercise. The end user feedback confirmed that this 'live' workflow can enhance the decision support and the emergency information management through near real–time situation awareness during and after a damaging event.
