Blending Vector Map Data with Satellite Imagery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vector-based maps become less interesting as users zoom in due to reduced detail and feature separation, leading to a lack of visual interest as the map data density decreases.
Innovation Solution
Implementing a system where, upon reaching a visual threshold, alternate imagery such as satellite images is blended with the map, specifically replacing or overlaying certain polygons based on feature types, user selection, or characteristics, to enhance detail and interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the zoom factor of a map becomes larger, then the detail of individual features can be seen more clearly, but features in the map appear to move farther apart and the map becomes less interesting to the user
Solution Approach 1:
The patent combines vector map data with satellite imagery to create a hybrid display. When zoomed in, the system overlays satellite imagery onto the vector map, merging two different data sources to maintain both feature detail clarity and overall map context. This allows users to see individual feature details clearly while preserving the density and interest of the overall map view.
Solution Approach 2:
The patent creates a composite visual representation by combining vector-based map features with raster-based satellite imagery. This composite approach allows the system to leverage the scalability and clarity of vector graphics for individual features while using satellite imagery to maintain visual interest and detail density at higher zoom levels.
2Reliability
If the map is vector-based, then the quality of the rendered image may never actually degrade, but eventually there may be very little detail available to render on the display
Solution Approach 1:
The system merges vector map data with satellite imagery to overcome the limitation of vector maps running out of detail. By combining these two data sources, the system maintains reliable, scalable vector rendering while supplementing it with satellite imagery that provides additional visual detail and context that vectors alone cannot provide.
Solution Approach 2:
The patent makes the map display system multi-functional by enabling it to switch between or combine vector-based rendering and satellite imagery rendering. This universality allows the system to adapt to different zoom levels and user needs, maintaining image quality through vector scaling while providing rendered detail through satellite imagery when vectors become insufficient.
Data Source
AI summary
In one aspect, a map is provided for display by one or more computing devices. The map includes one or more polygons. The one or more computing devices receive a zoom request for viewing the map. The one or more computing devices then determines whether a visual threshold has been reached based at least in part on the zoom request. When the visual threshold has been reached, the one or more computing devices identify a polygon of the one or more polygons. The one or more computing devices then provide for display alternate imagery corresponding to the polygon on the map.
