Abstract:
1. A method for generating a digital map that is stored on an electronic storage medium and in which a geographic area is described by a multitude of data sets, the method comprising the following steps: a) loading an original database, in which the geographic area is described by the multitude of data sets, into an electronic analyzer, wherein each data set describes an object of the digital map, wherein said each data set consists of a defined number of attributes, and wherein each attribute assumes 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 respectively assigned combination characteristics as a first partial database of the digital map, e) analyzing all data sets of the original database, wherein a new data set is generated for each data set of the all data sets by replacing the attribute value combinations or attribute value subcombinations that exist in said each data set with the combination characteristic assigned to the attribute value combinations or attribute value subcombinations, and f) storing the new data sets in a second partial database of the digital map, wherein a new data class model with an assigned class model designation is respectively generated when a new attribute value subcombination is detected, wherein each data class model describes a certain data type by several unchangeable class attributes and a certain number of changeable model attributes, and wherein the combination of unchangeable class attributes of new data set model corresponds identically to newly detected attribute value subcombination, the class model designation of newly generated data class model is set as combination characteristic,
