PROBLEM TO BE SOLVED: To provide a disaster management computer application system processor which acquires data collected by a survey method using an electromagnetic wave radar, which is data-managed in common, and displayed by a common display method, and which simultaneously displays the data as necessary and displays the data together with map information selected by a user, in management of piers, river embankments, and quay roads as well as cavities under road surfaces of route roads.SOLUTION: A hierarchical risk display system receives map data from an input/output device, receives map display means for displaying a map in a display device and cavity attribute information from the input/output device, and includes: cavity symbol display attribute determination means for specifying a display attribute of a cavity display symbol from the cavity attribute information: and superimposed display means for displaying the map and the cavity display symbol in the display device in a superimposed manner. A group of the cavity display symbols selected from the cavity display attribute determined according to a hierarchical depth range of a top surface of the cavity attribute information is displayed on the map by the map display means, the cavity display means, and the superimposed display means so as to prioritize the cavity display symbol having a small depth. |
