To provide information so that the same processing target section as the processing target section specified by the local device can be specified (reproduced) by other devices as well, and enable related information pertaining to the processing target section to be obtained.SOLUTION: A route search unit 109 searches for a route and obtains a search result that includes point-sequence information, and a target section specification unit 110 specifies a processing target section from this search result on the basis of type-of-road information. With respect to the point-sequence information of the specified processing target section, a first thinning-out unit 111A leaves a first point and thins out the other points out of points of road having the same attribute information. A provision request formation unit 113 forms a related-information provision request that includes data after thinning-out, provides it to a provision server 2 and obtains provision information from the provision server 2, then a route information provision unit 115 provides this to the portable terminal of a route search requester.SELECTED DRAWING: Figure 2

    【課題】 自機で特定した処理対象区間と、同じ処理対象区間を他の装置でも特定(再現)できるように情報提供し、当該処理対象区間に関する関連情報を得られるようにする。【解決手段】 ルート探索部109がルート探索して点列情報を含む探索結果を得て、この探索結果から対象区間特定部110が、道路の種別情報に基づいて処理対象区間を特定する。第1の間引処理部111Aは、特定された処理対象区間の点列情報について、同じ属性情報を有する道路の点については、最初の点を残して他の点を間引き、提供要求形成部113が、間引き後データを含む関連情報提供要求を形成して、提供サーバ2に提供し、提供サーバ2からの提供情報を得て、これをルート情報提供部115がルート探索要求元の携帯端末に提供する。【選択図】図2
