Abstract
A system and method for aligning maps using polyline matching is provided. A global map and a local map are represented as polyline maps including a plurality of line segments. One or more approximate matches between the polyline maps are identified. One or more refined matches are determined from the approximate matches. The global map and the local map are aligned at the one or more refined matches.
