Abstract
Official abstract text for this publication.
A method of operation of a navigation system includes: preprocessing an intersection from map data into an edge in query data; generating a route having a turn at the intersection; and sending the route for displaying at a device and for maneuvering the turn at the intersection by querying the query data for the edge of the intersection.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operation of a navigation system comprising: generating a validity flag for validating a starting location and a target destination; preprocessing an intersection from map data into an edge in query data; updating revised data in the query data; generating a route having a turn at the intersection with a control unit based on the validity flag representing valid; generating a warning representing the route cannot be generated based on if…
