Gis & Visual Analytics on Grid Technology

To prevent casualties both in human lives and ill private/public property due to Environmental Hazards Such as Floods or Forest Fires, it is required that large-scale Integrated Technological Systems are developed to detect in time ail imminent event. Such Systems use highly efficient computational engines to perform simulations oil natural phenomena in real time, they use web-applications to retrieve Geographic and Meteorological Information to be used as input for the aforementioned Simulation Models, they Visualize simulation-output via GIS technology so that the visual result meets high quality standards in terms of information mapping. Technology, Architecture and Design Of Such a System is presented in this chapter.
