An Evaluation of Data Sources for Entry Decision Support in Rapid-Onset Disasters
If time-sensitive relief is to be dispatched to a far-away location, the decision to do so – the “entry” decision – has to be taken within hours after the disaster for the relief to make an impact. This paper aims to identify which information sources that become available to the decision maker at what time after a potential disaster, and to establish how the provided information can be best utilized based on its inherent and accumulated quality. The research encompasses 46 case studies in central Asia in the period from 1993 to 2003. The study makes clear that a decision-maker will only benefit from satellite imagery if the time required to deliver a digested product to the decision maker is reduced to a matter of hours or if the area of interest is so remote or widespread that the time necessary for on-site reports exceeds that of acquiring and interpreting remotely sensed imagery. In conclusion, model-based decision support systems are important since they provide an early alert that enables other sources to quicker provide information that is more refined.
