This map illustrates the OsmAnd routing concept. The route starts in the Start Area Cluster (221558), moves to the nearest Border Point, and continues through precomputed Shortcuts across intermediate clusters. It then enters the Finish Area Cluster (221536) via another border point and finishes using local roads. This method speeds up routing by combining local search with efficient inter-cluster shortcuts.

Range queries ask "what's inside this box?" But sometimes the question is "what's nearest to this location?" This is the nearest neighbor problem, and you don't know how big your search radius should be. The nearest point might be right next to you or far away.
