Route Nowcast Map Display for Weather Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional weather forecasting systems provide inaccurate and coarse time-scale predictions, making it difficult for users to anticipate precise weather conditions at specific locations and times, especially for short-term forecasts along routes, which limits their ability to avoid extreme weather conditions.
Innovation Solution
A computer-implemented method that generates maps by obtaining nowcasts for key points along a route between a departure and destination location, using a nowcaster to provide very short-term weather forecasts, and visual indicators on the map to display these forecasts, allowing users to adjust their routes accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional weather forecasting systems are used, then weather predictions are provided for general areas, but the precision of location-specific weather information is insufficient
Solution Approach 1:
The patent segments the route into multiple key points and obtains separate nowcasts for each key point. This segmentation allows the system to provide location-specific weather information for precise locations along the route rather than general area forecasts, directly improving measurement precision for location-specific weather information.
Solution Approach 2:
The patent implements local quality by providing customized nowcasts for each specific key point along the route based on its unique location characteristics. Each key point receives weather information tailored to its specific geographic coordinates, ensuring that the weather data reflects local conditions rather than regional averages.
2Measurement precision
If conventional hourly weather forecasts are used, then weather information is provided at coarse time intervals, but the precision of time-specific weather information is insufficient
Solution Approach 1:
The patent implements periodic action by updating nowcasts at multiple time intervals (current time, intermediate time, and arrival time) rather than relying on fixed hourly forecasts. This periodic updating approach provides weather information at precisely when and where the user needs it, improving time-specific weather information precision without requiring continuous high-frequency updates.
Solution Approach 2:
The patent applies dynamics by making the forecast timing adaptive to the user's journey. The system dynamically adjusts when to provide weather information based on estimated arrival times at each key point, rather than using static hourly intervals. This allows the system to provide weather updates at optimal moments relevant to the user's movement along the route.
3Reliability
If conventional area-based weather forecasts are used, then general weather conditions are displayed, but the accuracy for precise locations within the area is insufficient
Solution Approach 1:
The patent segments the broad weather forecast area into specific key points along the user's route. By obtaining nowcasts for each individual key point rather than a single area-wide forecast, the system recovers detailed location-specific weather data that would otherwise be lost in generalized area-based forecasts, thereby improving reliability for precise locations.
Solution Approach 2:
The patent uses key points as intermediaries between the user's route and the weather forecasting system. Each key point serves as a mediator that translates the user's geographic path into specific weather information requests, ensuring that detailed location-specific weather data is obtained for each relevant position along the route.
4Ease of operation
If users rely on conventional weather forecasts for route planning, then they lack real-time weather information along the route, but obtaining detailed nowcasts for multiple key points increases system complexity
Solution Approach 1:
The patent implements universality by designing a multi-functional system that combines route planning, key point identification, nowcast acquisition, and visual display into a single integrated solution. The system performs multiple functions simultaneously - it plans the route, identifies relevant key points, obtains weather nowcasts for each point, and displays the information visually - making route planning with weather information easier without proportionally increasing complexity.
Solution Approach 2:
The patent merges the weather information acquisition process with the existing route planning functionality. By combining the identification of key points along the route with the acquisition of nowcasts for those points, and integrating both with the visual display system, the patent creates a unified workflow that improves ease of operation while managing system complexity through consolidation.

AI summary
A system and method for displaying nowcasts along a route on a map. The system receives a map request including a departure location and a destination location from a user, and obtains map data including a route between the destination location and the departure location. A nowcaster is used for outputting nowcasts for a number of key points along the route. The system modifies the map data to include a visual indicator for each nowcast for each key point such that when the modified map data is executed on a display the nowcasts are displayed along the route between the departure location and the destination location.
