Claim 0:
1. A navigation system for generating turn segments, comprising:
a processor;
a memory module communicatively coupled to the processor;
a segment list stored in the memory module, wherein the segment list includes a plurality of known segments; and
machine readable instructions stored in the memory module that causes the navigation system to perform at least the following when executed by the processor:
identify a current location of the navigation system;
search the segment list for at least one known segment candidate that is within a threshold distance of the current location;
determine whether at least one known segment candidate from the segment list includes the current location;
track turn movements of the navigation system to detect a turn and, in response to detecting a turn, to form an unknown segment upon determining at least one known segment candidate does not include the current location; and
detect another turn and, only in response to detecting the another turn, link the unknown segment to the plurality of known segments from the segment list.
