Disclosed herein are methods for decoding path data. The methods may comprise providing a navigation database for storing topological information of a road network. The navigation database comprises a plurality of road links, and a plurality of link nodes, each link node defining a topological connection between two or more of the road links. The methods may further comprise receiving path data indicative of a path within the road network, wherein the path data comprises a start identifier, a link count, and at least one exit number. The methods may further comprise selecting, from the navigation database, one road link of the plurality of the road links as a start road link of the path based the start identifier. Moreover, the methods may comprise iteratively expanding the path with selected road links until the link count is equal to the number of road links of the path.
