First Claim
Patent Images
1. A method comprising, at a mobile station:
- receiving a conceptual map of a navigable area, said conceptual map including two or more topological elements being related to one another in said conceptual map by a first set of dimensions;
applying one or more ground truth measurements or topological constraints to said first set of dimensions of said conceptual map to provide a modified map having corrected dimensions; and
mapping an estimated location of the mobile station to said modified map.

Abstract
Disclosed is a method for receiving a conceptual map of a navigable area, the conceptual map including two or more topological elements being related to one another in the conceptual map by a first set of dimensions; applying one or more ground truth measurements or topological constraints to the first set of dimensions of the conceptual map to provide a modified map having corrected dimensions; and mapping an estimated location of the mobile station to the modified map.
