Adaptive Map Zoom by Travel Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mapping applications often display an initial map with a fixed zoom level of a few miles around the user's location, which is not optimal for rural or densely populated areas, as it may show too few or too many points of interest (POIs), not aligning with the user's typical travel distance and needs.
Innovation Solution
A mapping application that estimates the distance a user can travel within a given time period based on their location, traffic conditions, and mode of transport, adjusting the zoom level to display an initial map with a radius that includes POIs within reasonable travel distance, thereby providing a more suitable initial view without requiring manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed zoom level of a few miles is used for the initial map view, then the map can be displayed quickly with consistent performance, but it shows too few POIs in rural areas and too many POIs in densely populated areas, failing to align with user travel needs
Solution Approach 1:
The patent implements dynamic zoom level adjustment by transitioning from a fixed zoom level to a variable zoom level that adapts to the user's location characteristics. The system dynamically determines the appropriate zoom level based on real-time analysis of POI density and estimated user travel distance, ensuring the map view is always optimized for the current geographic context without requiring manual user intervention.
Solution Approach 2:
The patent changes the zoom level parameter based on the analyzed geographic characteristics. By calculating POI density and estimated travel distance as input parameters, the system determines an optimal zoom level parameter that adapts to different areas. This parameter change enables the map to automatically adjust between showing fewer POIs in rural areas and more POIs in urban areas, directly resolving the adaptability issue.
2Quantity of substance
If the initial map shows a one or two mile radius, then it provides a consistent view for all users, but it shows too little content in rural areas where POIs are spread out and too much content in urban areas where POIs are densely packed
Solution Approach 1:
The patent implements self-service by enabling the map system to automatically determine and adjust the appropriate zoom level without requiring manual user intervention. The system analyzes POI density and estimated travel distance, then autonomously selects the optimal zoom level, eliminating the need for users to manually zoom in or out to achieve a useful initial view.
Solution Approach 2:
The patent uses feedback mechanisms by analyzing the relationship between geographic location, POI density, and estimated travel distance to determine the optimal zoom level. This feedback loop ensures that the number of POIs displayed is appropriately adjusted based on the characteristics of the specific area, providing users with a relevant initial view that matches their location context.
3Adaptability or versatility
If a fixed initial zoom level is used, then the application can be implemented simply with consistent performance across all locations, but it does not account for differences in typical travel distances between rural and urban areas
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing characteristics of different geographic areas, including POI density and estimated travel distances. When a user requests a map view, the system quickly retrieves pre-analyzed data for the user's location and immediately determines the appropriate zoom level, avoiding the need for complex real-time calculations while still providing adaptive results.
Data Source
AI summary
Systems and methods are provided for generating a mapping application that displays an initial map with a zoom level that is based on a travel time associated with the location of the user. The mapping application receives a request to present a digital map from a client device. Based on the current geographic location of the client device, the mapping application estimates a distance in which a user of the client device can travel within a particular time period. The mapping application then selects a parameter for a viewport of the digital map based at least on the estimated distance. For example, the viewport parameter may be a zoom level. The mapping application then generates the digital map in accordance with the selected parameter, and displays the digital map via a user interface of the client device.
