Building Service Oriented Applications for Disaster Management - An Earthquake Assessment Example

摘要

GIS could help rescuers for disaster management to assess the fitness for use of spatial data to reduce the risk of decision-making. However, GIS presents limitations and remain largely unused. It needs to provide the required information to rescuers with high quality. In this paper, we develop a prototype system to grant the data quality. The system aims to provide rescuers with information in a rapid and intuitive way in order to reduce rescuer decision-uncertainty due to poor data quality (DQ). We define an extensible QoS model for DQ evaluation and a proposed statistics algorithm to predict the decision risks. Our implementation demonstrates the applicability of the proposed model in supporting disaster management.
