The Implementation Of The Shortest Path Based On The Gis Fire Information System

Along with the economical unceasing development, in the city each kind of unstable safety factor gradually does not increase, but the fire is Gao Juge plants Yi Faxing the accident the first place, in order to a more effective local constable protects national and people's life and property security,Sharpens the fire prevention quick reaction capability. The establishment modernization fire correspondence command system has become the urgent matter, the fire department needs to utilize the geographic information system formidable space analysis function, Establishes to be able nimbly to inquire each kind of related information, to carry on the fire to analyze the simulation, to provide the fast support plan and the assistance decision-making fire ahead of time simulates the analysis and the emergency command system, Thus uses the limited manpower, the physical resource maximum limit enhances saves goal the efficiency, reduces the policy-making deviation, the reduction fire damage, the high efficiency the quick reaction capability and the whole direction operational capacity which enhances the fire department to save goal.This meaning of a text to has conducted the research based on in the GIS city intelligence fire prevention management system management system most short-path analysis. The most short-path question is in the city intelligence fire prevention management system management system rapid reaction realization process the most basic question, it is completes the fire task the foundation, holds the important status in the city intelligence fire prevention management system management system. This article introduced related geographic information system some basic concepts, including the geographic information system concept, the geographic information system development and the present situation, the geographic information system application domain, the geographic information system data model, the geographic information system data organization and the management, in the geographic information system network analysis, have summarized the geographic information system application software MapInfo characteristic. In view of the city system characteristic, to the essential technology which analyzed based on the city system most short-path has conducted the research and the confirmation. Proposed one kind practical, highly effective most short-path analysis solution, and has realized a most short-path analysis experiment system in this foundation. Among them, solved the city system vector map expression, the network topology with emphasis has withdrawn and constructs, the most short-path algorithm highly effective realization and so on the essential technology. And aimed at a large-scale data set to carry on the test, the test result had proven the experimental system speed of response and the analysis efficiency could-satisfy the fire management emergency system the application demand.
