1. A map information processing apparatus comprising:

  • a receiver that receives past map information including a past road link and current map information including a current road link; and

    a data extractor that extracts a difference between a shape of said past road link and a shape of said current road link as update data for updating predetermined map information,wherein at least one of the current road link and the past road link is characterized with finite width of greater than zero representative of a buffer region, wherein said data extractor does not extract said difference as said update data in a case where one road link of said current road link falls within the path of the other of the current road link and the past road length considered with the finite width representative of the buffer region and only extracts the difference when the current road link of the update data falls outside of the path of the past road link when considered with the buffer region.
