Abstract: Some embodiments provide a method for generating intersection data for paths in a map region. The method receives a set of junctions at which paths intersect in the map region. For a particular junction of at least two paths, the method automatically determines whether any of the other junctions in the map region satisfy criteria to be part of a single intersection with the particular junction. When at least one of the other junctions satisfies the criteria, the method automatically combines the other junctions that satisfy the criteria with the particular junction into a single intersection for use in performing mapping operations.
