Flood visualization is an effective and intuitive tool for representing flood information from abstract spatiotemporal data.With the growing demand for flood disaster visualizations and mitigation,augmented flood visu...
The original Digital Earth concept,formulated by Al Gore(1998),is essentially a virtual reality system.In this(imagined)system,users are able to freely explore all possible recorded knowledge or information about the ...
Virtual reality(VR)is a frequently emphasized issue on the Digital Earth(DE)agenda.While current DE research is more engaged in the technical aspects of VR applications,this paper focuses on what is possible with imme...
Computer-based evacuation simulations are important tools for emergency managers.These simulations vary in complexity and include 2D and 3D GIS-based network analyses,agent-based models,and sophisticated models built ...
Global environmental change is one of the major distinguishing features associated with the contemporary world political map. It is significant not only because it illustrates the intersections between geopolitics and...
Riverine flood event situation awareness and emergency management decision support systems require accurate and scalable geoanalytic data at the local level. This paper introduces the Water-flow Visualization Enhancem...
3D desktop-based virtual environments provide a means for displaying quantitative data in context.Data that are inherently spatial in three dimensions may benefit from visual exploration and analysis in relation to th...
Use of GIS in public health is currently limited to tracking immunizations, disease surveillance, and establishing new service areas. The potential of GIS to improve planning, implementation and monitoring of programs...
Risk communication is a significant challenge in risk management.It serves different purposes;an important one is to improve the public risk awareness and mitigation.Because of the strong spatio-temporal component of ...
