Time series visualization method of disaster damage history

摘要

The present invention relates to a method of visualizing disaster damage history in a time series, In a system consisting of information related to natural disasters, a program for predicting storm and flood damage based on the information, and an operating computer, and a monitor for simulating storm and flood damage, the following process is performed by the program. characterized. 1) When the information related to the natural disaster is introduced, the total amount of damage by city, county, and district by cause of the disaster annual report, recovery cost, and detailed damage amount by facility are converted into a database, but based on the period and cause of damage, the process of linking with past disasters; 2) The process in which the databaseized disaster information is tabulated with major disaster information and damage/recovery ratio, such as the date of occurrence, intensity, size, maximum wind speed, movement speed, central atmospheric pressure, damage amount and recovery cost, 3) A process in which the disaster radius and route are displayed on the map display window by mapping the tabulated disaster information on the map; 4) One disaster information from among the multiple disaster information databased in step 1) is used as the standard disaster, a comparative disaster is selected from the rest of the disaster information, and the disaster information mapped in step 3) is compared to the standard disaster and comparative disaster. The similarity of disasters is calculated by displaying them together on the map. The similarity of the above disasters is calculated by the conditions of the movement route, central pressure, and landing point between the reference disaster and the comparative disaster, The similarity calculation method based on the movement route between disasters takes the starting point when the disaster enters the border area of Korea and the end point when it leaves the border zone in Korea, and the distance from the start point to the end point of each standard disaster and comparative disaster. Calculate the average by calculating the sum of the distances and dividing by the total number of points, sorting the average distance between the reference disaster and the comparative disaster in descending order, and calculating the similarity based on the minimum value, The similarity calculation method based on the difference in central pressure calculates the absolute value of the difference in central pressure between the reference disaster and the comparative disaster when a disaster enters the border area of Korea, then sorts the calculated values in descending order to calculate the similarity based on the minimum value. becomes, The similarity calculation method based on the difference in landing points is divided into three categories: judging whether a disaster has entered within the border area of Korea, and if it enters, it is classified as an attempt at the landing point, and if it does not enter, it is divided into the west sea route or the east sea route. The process of calculating the similarity of disasters by single or multiple combinations of conditions of movement path, central pressure, and landing point between the reference disaster and the comparative disaster by calculating the similarity.
