Abstract

Les informations d'environnement actuelles n'exercent qu'une influence limitée dans la représentation ou le calcul d'itinéraire des systèmes de navigation habituels. L'invention résout ce problème dans le fait que des images satellites actuelles d'une position requise sont demandées et des informations actuelles d'environnement sont déterminées à l'aide des images satellites telles que par exemple des places de stationnement disponibles, des bouchons, des travaux ou des conditions climatiques défavorables.
