PROBLEM TO BE SOLVED: To provide a map matching device that displays a current position at a correct position in a road in a map.SOLUTION: A map matching device comprises: an SSD 15 that stores mountain climbing map data 15A; a GPS antenna 11 and a GPS reception unit 12 that measure the current position; an atmospheric pressure sensor 21 that measures an atmospheric pressure of the current position; a main memory 14 that stores the measured current position and atmospheric pressure in association with each other; and a CPU 13 that matches a corresponding mountain climbing road position in the mountain climbing map data 15A on the basis of the measured current position, and determines presence or absence of overlapping of the road position by a history of the matched road position, and when it is determined that the overlapping of the road position exists, compares an atmospheric pressure of a current position to be measured with the atmospheric pressure stored in association with the stored current position, and causes a candidate of the matching road position to be changed on the basis of a result of the comparison.SELECTED DRAWING: Figure 1

    【課題】現在位置を地図中の道路における正しい位置に表示するマップマッチング装置を提供する。【解決手段】登山地図データ15Aを格納したSSD15と、現在位置を測定するGPSアンテナ11及びGPS受信部12と、現在位置の気圧を測定する気圧センサ21と、測定した現在位置と気圧とを関連付けて記憶するメインメモリ14と、測定した現在位置に基づいて登山地図データ15A中の該当する登山道位置にマッチングし、マッチングする道路位置の履歴により道路位置の重複の有無を判定し、道路位置の重複があると判定した場合に、測定する現在位置の気圧と、記憶する現在位置に関連付けて記憶した気圧とを比較し、その比較結果に基づいてマッチングする道路位置の候補を変更させるCPU13とを備える。【選択図】図1
