Topological Map Navigation with Scale Data Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems provide accurate navigation-related features for maps-to-scale but lack integration of these features for topological maps, which do not offer geographic accuracy or scaling, limiting their ability to provide users with comprehensive navigation functions.
Innovation Solution
Methods for providing location-based information on topological maps by receiving queries, accessing map-to-scale data, identifying corresponding points or links, and displaying this information in relation to topological maps, allowing for the integration of navigation features like route guidance and point-of-interest information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If navigation systems use topological maps, then the system can provide simplified map views and easier navigation, but the system loses geographic accuracy and scaling information
Solution Approach 1:
The patent combines topological maps and maps-to-scale into a unified navigation system. The system maintains both map types and allows users to switch between them or use them together, merging the simplicity of topological maps with the geographic accuracy of maps-to-scale into a single comprehensive navigation solution
Solution Approach 2:
The navigation system is designed to support multiple map types (topological and maps-to-scale) with the same set of navigation features and functions. This multi-functionality allows the system to provide simplified navigation when needed while maintaining the option for accurate geographic representation when required
2Measurement precision
If navigation systems provide detailed map-to-scale information, then users get accurate geographic data, but the system complexity increases
Solution Approach 1:
The system dynamically adjusts between different map representations based on user needs and context. Users can switch between topological and map-to-scale views, and the system adapts the level of detail and complexity presented, making the system manageable while providing comprehensive functionality when needed
Solution Approach 2:
The patent segments the map information into different layers and types (topological vs. map-to-scale), allowing the system to present only the necessary level of complexity for each situation. Users can access detailed information when needed while viewing simplified representations during normal operation

AI summary
Disclosed herein are methods of providing location-based information with respect to a topological map. A method may include (a) receiving a query for location-related information, (b) optionally generating data representing the topological map, (c) accessing the location-related information in a map-to-scale, (d) optionally determining an association between one or more points (or links) in the map-to-scale and one or more corresponding points (or links) in a topological map, (e) identifying one or more points (or links) in the map-to-scale that relate to the location-related information and that correspond to one or more points (or links) in the topological map, (f) optionally determining a relative position of the location-related information with respect to the identified one or more map-to-scale points (or links), and (g) displaying the location-related information with respect to the corresponding one or more points (or links) in the topological map.
