Abstract

L'invention concerne un procédé permettant l'introduction de données géographiques dans un système de navigation. Les données géographiques sont en rapport avec une indication d'un lieu saisissable par un utilisateur. Le procédé proposé prévoit que des données supplémentaires saisissables électroniquement en rapport avec l'indication du lieu soient mises à disposition. Ces données contiennent les données géographiques. De plus, il est prévu que les données supplémentaires soient saisies à l'aide d'un système de réception (105) et que les données géographiques du système de navigation contenues dans les données supplémentaires puissent être mises à disposition par l'utilisation du système de réception (105). A l'aide des données géographiques, des informations de guidage peuvent être déterminées dans le système de navigation. De plus, l'invention concerne un dispositif approprié destiné à la réalisation du procédé ainsi qu'un dispositif permettant de mettre à disposition et/ou de reproduire une indication d'un lieu qui peut être saisie par un utilisateur. L'invention comprend également un dispositif permettant de mettre à disposition des données supplémentaires contenant des données géographiques qui sont en relation avec l'indication du lieu et qui peuvent être saisies à l'aide d'un système de réception (105) relié à un système de navigation.
