Title (EN) NAVIGATION APPARATUS AND SERVER APPARATUS
(FR) APPAREIL DE NAVIGATION ET APPAREIL SERVEUR
(JA) ナビゲーション装置及びサーバ装置
Abstract: front page image
(EN)A navigation apparatus acquires geographic information from a server apparatus. When the navigation apparatus does not store any geographic information that provides a continuous route from a starting point to a destination point, it transmits data of the staring point and destination point to the server apparatus to acquire therefrom geographic information that provides a continuous route from the starting point to the destination point. This efficient acquisition of geographic information realizes reduction of communication time and communication costs.
(FR)La présente invention concerne un appareil de navigation qui acquiert des informations géographiques provenant d'un appareil serveur. Lorsque l'appareil de navigation ne stocke aucune information géographique qui offre un trajet continu d'un point de départ à un point de destination, il transmet des données concernant le point de départ et le point de destination à l'appareil serveur afin d'acquérir des informations géographiques offrant un trajet continu du point de départ au point de destination. Cette acquisition efficace d'informations géographiques permet de réduire le temps de communication et les coûts de communication.
(JA)本発明に係るナビゲーション装置は、サーバ装置から地図情報を取得する装置であり、ナビゲーション装置が出発地から目的地までの連続した地図情報を記憶していないときは、サーバ装置へ出発地及び目的地を送信し、サーバ装置より出発地から目的地までの地図情報を取得するものである。そして、地図情報を効率良く取得することにより、通信時間の短縮及び通信費の削減を実現している。
