Disaster Information Visualization With Future Scenario Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disaster information systems only provide real-time notifications and lack the ability to predict future disaster information, making it difficult to plan evacuations and recovery operations after a disaster occurs.
Innovation Solution
A system that includes a past disaster information storage section, a disaster information acquisition section, a disaster prediction section, and a display control section to superimpose current and predicted disaster information on a display, allowing for visualization of past, present, and future disaster scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only current disaster information is provided, then the system is simple and easy to operate, but the ability to predict future disaster information and support evacuation planning is insufficient
Solution Approach 1:
The disaster prediction section performs preliminary prediction of future disaster information based on current disaster information and past disaster patterns. This allows evacuation planning to be done in advance rather than reacting to disasters after they occur, resolving the contradiction by providing future information through predictive analysis.
Solution Approach 2:
The system adds a temporal dimension by incorporating past disaster information and predicting future disaster information, transforming the system from providing only current snapshot data to providing historical context and future projections, thereby reducing information loss without proportionally increasing complexity.
2Reliability
If disaster prediction functionality is added, then evacuation planning capability is improved, but the system complexity increases
Solution Approach 1:
The disaster prediction section serves multiple functions: it analyzes current disaster information, compares it with past disaster patterns, predicts future disaster development, and supports evacuation planning. This multi-functionality improves reliability without requiring separate dedicated systems for each function.
Solution Approach 2:
The disaster prediction section acts as an intermediary between current disaster information and evacuation planning decisions. It processes and transforms raw disaster data into predictive insights that guide evacuation strategies, thereby improving reliability while managing complexity through a dedicated intermediary component.
3Loss of information
If only current disaster information is displayed, then the display is simple and clear, but the comprehensive view for decision-making is insufficient
Solution Approach 1:
The display control section merges current disaster information with predicted future disaster information into a single comprehensive display. This integration provides decision-makers with a complete view of the disaster situation across time, reducing information loss while maintaining display simplicity through unified presentation.
Solution Approach 2:
The display adds a temporal dimension by showing both current and predicted future disaster information together, transforming the display from a static snapshot to a dynamic time-based visualization. This provides comprehensive disaster views without overwhelming users, as the temporal progression is clearly organized.

AI summary
A past disaster information storage section (28) that stores disaster information related to a disaster that has occurred in the past and a disaster information acquisition section (32) that acquires current disaster information related to a disaster that has occurred this time are included. A disaster prediction section (35) that predicts future disaster information caused by a disaster that has occurred this time on the basis of current disaster information acquired by the disaster information acquisition section (32) and past disaster information stored in the past disaster information storage section (28), and a display control section (37) that displays an image in which the current disaster information and the future disaster information are superimposed are further included.
