Navigation Map Background Data Generation for Seasonal Terrain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation systems fail to display terrain information and weather conditions, providing drivers with incomplete and unrealistic map data, which can lead to inadequate preparation for traffic conditions.
Innovation Solution
A system that generates background data based on real-time weather information and pre-stored seasonal patterns and colors, associating it with map data to provide a more realistic route guidance, including terrain classification and weather conditions like rain or snow, to create a background environment similar to the real view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If map data is focused mainly on route data and POI information, then the navigation system can provide clear route guidance, but terrain information and weather conditions are not displayed, resulting in fragmentary information for drivers
Solution Approach 1:
The map data is segmented into multiple layers including route data layer, terrain information layer, and weather condition layer. Each layer contains specific types of information and can be independently managed and displayed, allowing the system to provide comprehensive information without overwhelming complexity
Solution Approach 2:
Multiple types of data (route data, terrain information, weather conditions) are merged into a unified map display system. The background data generation unit combines these different data sources to create a comprehensive map view that presents all information in an integrated manner
2Reliability
If map data does not include weather information, then the system maintains simple data processing, but drivers cannot expect and cope with traffic conditions
Solution Approach 1:
Weather information and terrain data are pre-processed and stored as background data before being needed for navigation. The system prepares multiple seasons' background information in advance, so when navigation is required, the data is already organized and ready for quick integration with real-time weather updates
Solution Approach 2:
A background data generation unit acts as an intermediary between raw weather data and the navigation display. This unit processes weather information and terrain data, converting them into a format suitable for integration with map data, thereby simplifying the overall data processing architecture
3Adaptability or versatility
If terrain information is not displayed in map data, then the navigation system maintains simple display structure, but drivers receive fragmentary information especially in suburban areas
Solution Approach 1:
The display structure dynamically adjusts based on the driving environment. In suburban areas with complex terrain, the system automatically displays more terrain information. The background data is selectively applied based on location, time of day, and weather conditions, making the display adaptable rather than static
Solution Approach 2:
Different levels of terrain information detail are applied to different geographic areas. Urban areas receive simplified displays focusing on routes and POIs, while suburban and rural areas receive enhanced terrain information including farmland, water systems, and topography. This local customization optimizes information completeness without uniformly increasing complexity

AI summary
A system for displaying a map, the system including: a map database maintaining map data associated with a route; a map data identification unit identifying map data corresponding to a driving route of a vehicle from the map database; an information receiving unit receiving weather information associated with a current seasonal weather from a background service server in real time; a background data generation unit generating background data according to an actual environment based on the received weather information; and a route guidance unit guiding a route by associating the map data with the generated background data.
