A method and a device are provided for outputting data records on the basis of input data records entered by a user, a set of data records present in a database being structured via a tree structure, and search criteria and filter information items being assigned to nodes in the tree structure which are not terminal nodes.

Searching a map database via a tree of nodes having multiple search criteria and filter items within a non terminal node

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

A method for destination selection in a navigation system in which each destination from a totality of all destinations is defined by destination parameters and a set of possible destinations from the totality of all destinations is limited step-wise due to the input of individual characters for one parameter. When inputting the characters, a switch may be made from one destination parameter to an input of a character for another parameter.

Method for selecting elements in a driver information system or in a navigation system or in a mobile terminal

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.

Navigation system and method for supporting destination input in a navigation system

A method is proposed for entering place names into a device for processing the place names, in particular into a navigation device in a vehicle, where in the case that a match of a place name is ambiguous, a graphical representation for distinguishing the respective places of the same name is displayed for selection of the particular place.

Method for inputting local names

A method of inputting a navigation destination into a navigation device, where a place name of the navigation destination is entered, where in the event that there are, in a navigation database, a plurality of navigation destinations having the same place name, supplemental information is output for the plurality of navigation destinations, allowing differentiation of the navigation destinations in each case. With this method, the supplemental information includes information about the direction and/or distance from a nearby or nearest prominent point. A navigation database for performing the method, in which position coordinates, in particular central point position coordinates, are stored for each stored navigation destination and for each of the prominent points which may be output as part of the supplemental information. This facilitates resolution of ambiguity when entering navigation destinations which is improved for the user, because it may be more easily understood.
