Use of GIS for disaster prevention and mitigation is now being more and more people are concerned. In addition to weather forecasting, GIS in this snow disaster which could play a role? Interview with Xinhua, China's emergency management experts ESRI Non-Chen.
"In fact, the GIS used in the heavy snow emergency management is not only theoretically feasible, there are a lot of success in domestic and international practice." Chen said non. After the snowstorm, GIS can not only reflect the road conditions and traffic incidents, but also on snow removal vehicles, personnel, and other materials for deicing scheduling and allocation, greatly increase efficiency and ensure smooth traffic. In water supply, water supply systems through GIS location and depth of buried pipeline information retrieval, in combination with other analysis of the cracking of the pipeline by means of easy to focus on protection facilities. In power terms, GIS can be used to track the fault point, and timely use of mobile GIS fault information collection and feedback to the rapid restoration of electricity.
Non-Chen said: "In the United States Buffalo, New York, people also use GIS to manage the trees damaged in the snowstorm, prevent injury or damage trees and public facilities. If the snow emergency departments are able to establish emergency response GIS system and share information through the network, then a comprehensive analysis of such information will greatly enhance our ability to deal with snow.
