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.

An integrated optical circuit is described for coupling an optical fiber amplifier with two or four terminals in such a way that the optical fiber amplifier is supplied with optical signals in a prescribed direction, and the optical signals are coupled out to an optical network via a directed directional coupler. The necessary optical switches, couplers, terminals and light guides are integrated into the integrated optical circuit.
