Abstract:
Systems and methods are provided for providing improved generation of textual directions based on positional information. In an implementation, textual directions for traversing a path are generated based on positional information associated with the path. According to a method, positional information that specifies a longitude and latitude at a plurality of times is received and processed to generate a routing graph. The generated routing graph includes nodes and route links that connect the plurality of nodes. Textual directions are generated for traversing a path associated with the positional data, based in pan on link information associated with the links of the generated routing graph.
