ABSTRACT:
A method for generating a digital map that can be stored on an electronic storage medium and in which a geographic area is described by a multitude of data sets includes the following steps:a) loading an original database (01), in which the geographic area is described by a multitude of data sets, into an electronic analyzer, wherein each data set describes an object of the map, wherein each data set consists of a defined number of attributes, and wherein each attribute may assume a defined number of different attribute values,b) detecting attribute value combinations or attribute value subcombinations that occur in the data sets of the database,c) assigning a distinct combination characteristic to each attribute value combination or attribute value subcombination,d) storing the attribute value combinations or attribute value subcombinations detected in the database with the respectively assigned combination characteristics as a first partial database (02) of the digital map,e) analyzing all data sets of the original database (01), wherein a new data set is generated for each data set by replacing the attribute value combinations or attribute value subcombinations that exist in each data set with the combination characteristic assigned to the attribute value combinations or attribute value subcombinations, andf) storing the new data sets in a second partial database (03) of the digital map.
