  "textContent": "A map server includes a difficult place setting unit, a distribution map generation unit, and a distribution processing unit. The difficult place setting unit identifies, based on a cancel point report from a vehicle, a difficult place which is a point where vehicle control involving a driving support or automatic driving is highly likely cancelled. The distribution map generation unit generates, as a map of a difficult place area related to the difficult place, distribution maps respectively including map information denser than a map of a normal area that is an area other than the difficult place area. The distribution maps of the normal area, which does not include detailed map information, contributes to a reduction of data amount in an entire map distribution scheme, when, for example, distributing map data over the network.",
