Using a corridor search to identify locations of interest along a travel route
First Claim
1. A method for determining a location of interest, the method comprising:
- accessing data describing a hierarchy of subsections that cover a region, including;
accessing a first level in the hierarchy that is divided into one or more first subsections that cover the region,accessing a second level in the hierarchy that is divided into two or more second subsections that also cover the region, wherein the number of second subsections used to cover the region exceed the number of first subsections used to cover the region, andaccessing at least one of the first subsections on the first level and at least one of the second subsections on the second level that cover at least partially overlapping portions of the region;
selecting one or more subsections in the hierarchy of subsections for which locations of interest are to be identified; and
identifying one or more locations of interest associated with the selected one or more subsections.

Abstract
A corridor search process is used to identify locations of interest along a travel route. The corridor search process identifies locations of interest along a travel route by using a grid search process that first identifies shape points that correspond to the travel route. Each shape point is associated with a portion of a grid system used to delineate a region of geography through which the route traverses. The portions of the grid system correspond to a corridor along the travel route. References to redundant portions of the grid system are removed, and locations of interest are identified based on an association between a location of interest with a particular portion of the grid system.

15. An apparatus for determining a location of interest, the apparatus being configured to:
-
access data describing a hierarchy of subsections that cover a region, the accessed data describing; a first level in the hierarchy that is divided into one or more first subsections that cover the region, a second level in the hierarchy that is divided into two or more second subsections that also cover the region, wherein the number of second subsections used to cover the region exceed the number of first subsections used to cover the region, and wherein at least one of the first subsections on the first level and at least one of the second subsections on the second level cover at least partially overlapping portions of the region; select one or more subsections in the hierarchy of subsections for which locations of interest are to be identified; and identify one or more locations of interest associated with the selected one or more subsections. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
