A storage medium on which geographic data of a geographic region are stored together as map units, a corresponding method for generating a map from the geographic data, and a corresponding navigation device. In order to reduce the amount of data to be processed, the map units are structured hierarchically, map units of an norder respectively corresponding to one geographic partial region, n being a natural number, and map units of an (n+1)order respectively corresponding to one geographic subregion of one of the partial regions.

Storage medium for map data, method for generating maps, and navigation device

In a method for the input of a destination, first of all a category selection is made, destinations corresponding to the category selection subsequently being offered for selection, at least a portion of the destinations being assigned to at least one subordinate category that, in each instance, has a superordinate category, characterized in that a category selection is made such that in each case, a superordinate category is displayed for the category selection or the superordinate category is replaced by one or the plurality of categories subordinate to it, and in each instance, a replacement is made when the number of subordinate categories with respect to a superordinate category is less than a predefined first threshold value.

Method for the input of a destination and navigation device

A possibility for simplifying the inputting of the destination in a motor vehicle navigation system by providing the user with useful additional items of information for the specification of ambiguous destination indications. Such a navigation system includes means for destination input, a navigation module for route planning, and means for displaying information, in particular indications of location, additional items of information concerning the indications of location, and route information, the means for destination input supporting a hierarchical, interactive inputting of the destination, by providing the user, in the case of ambiguous textual destination indications, with a choice of destination alternatives, including additional items of specifying information, until an unambiguous destination indication is made. The textual destination indications are stored together with corresponding geographic coordinates. The geographic coordinates are used for the determination of the additional items of information for the specification of destination alternatives.
