There are many methods for dealing with spatial uncertainty. However, a separate discussion for attribute uncertainty of geographic information is still rare. With the rapid development of multiple sources of geographic data, the uncertainty of attributes and their fusion is important for accuracy assessment and decision making. Attribute uncertainty of geographic information is an important aspect...
With the urban extension, land development, land use change, and climate change, the increasing natural-society interaction breeds the environment of hazard risk for human society. Watershed hazard risk assessment has been continuously researched with changed natural environment and human activity. This paper has discussed integrated assessment approaches based on watershed natural-society dynamic...
Multi-sources geographic data give rise to a challenge for data integration and fusion and their application in natural resources and environmental assessment. Data heterogeneous and uncertainty are the main barriers for the integrated assessment and modeling. This paper will give formal modeling methods of assessment targets and related uncertainty theories. A target Geo-Entity model and graph based...
Assessment of flood risk is important to flood disaster forewarning and decision management. However, there are many uncertainty factors that influence flood risk assessment. In order to solve this problem, this paper proposes an information fusion method based on DS-AHP (Dempster-Shafer and Analytic Hierarchy Process) to deal with uncertainty information, and fuzzy set theory and GIS methods are...
Vulnerability analysis of human society in natural hazard is confronted with uncertainty and complex factors in given geographic area. The assessment of vulnerability is significant for decision-makers and their spatial planning exercises. However, vulnerability is hard to use quantity analysis because of the uncertainty in both model and data. In our approach, the exposure zone of hazard is introduced...
Risk analysis for flood hazard due to dam break is complex system problem. An information model for integrated complex factors of the system is useful for dam break risk analysis. Firstly multiple factors are analyzed using scenario analysis method, including factors and their uncertainty in environmental, engineering operation and hazard consequences. Then an information model of risk analysis for...
