METHOD FOR GENERATING INUNDATION INFORMATION USING WEATHER DATA AND NAVIGATION SERVICE METHOD USING THE SAME

摘要

PURPOSE: A flooding information generation and service method for a navigation device using the same for utilizing weather information for analyzing a link is provided to supply safe route by applying quantitatively indexed flooding information as a route search of a car navigation device. CONSTITUTION: A flooding-vulnerable link applying relative altitude is analyzed by using a digital elevation model(S10). A flooding risk index is generated(S20). A safety mode selecting the weighted value of the flooding danger index is selected(S30). The real-time weather information is transmitted the navigation device. A user applies the weighted value of the flooding danger index in the safety mode.
