Abstract
The automatic generation of multiple sets of directions for navigating geographically to a specific destination without specification of an origin. Based on the destination, candidate roads or other transportation conduits are selected for analysis. Candidate meta-departure points are analyzed and selected along the roads based on distribution about the destination, cardinal directions relative to the destination, road metadata, distance to the destination, driving time, and other factors. The number of departure points generated to represent routes to the destination from the several logical cardinal directions is minimized. The generated departure points also represent routes that a majority of people would likely take to the destination. Additionally, the generated departure points originate from places that users are likely to be familiar with and can get to without additional guidance. The final instruction sets for navigating to the destination are presented along with a map that identified the departure points.
