1. An automated method, comprising: projecting a plurality of known address points onto an address segment vector of a map database, to create projection points; interpolating locations for addresses of the address points, to create corresponding interpolation points; segmenting the address segment vector into a plurality of address sub-segment vectors, upon a distance between a projection point and a corresponding interpolation point exceeding a threshold distance; and determining at least one of a relatively largest distance among distances between corresponding projection and interpolation points, and an average distance between all projection point and corresponding interpolation point pairs; wherein the segmenting is performed upon at least one of the determined relatively largest distance exceeding the threshold distance, and the determined average distance exceeding the threshold distance.
