VOLUNTEERED GEOGRAPHIC INFORMATION FOR DISASTER MANAGEMENT WITH APPLICATION TO RAPID FLOOD DAMAGE ESTIMATION

摘要

All phases of disaster management require up-to-date and accurate information. Different in-situ and emote sensor systems help to monitor dynamic properties such as water levels or inundated areas. New ternet technologies have facilitated fast and easy data collection from the public, giving rise to the idea using Volunteered Geographic Information (VGI) to aid disaster management. This paper discusses the opportunities and challenges of using VGI for disaster management with particular focus on information for Vie response and recovery phases. Different approaches to assessing VGI data quality are presented and disussed. In a case study, the fitness for use of observations from the affected population for rapid flood damkge estimation is demonstrated to be comparable to estimates based on hydraulic modelling. Further esearch needs with respect to the case study and to VGI for disaster management in general are identified.
