Abstract

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 nth order respectively corresponding to one geographic partial region, n being a natural number, and map units of an (n+1)th order respectively corresponding to one geographic subregion of one of the partial regions.
