METHOD FOR UPDATING DIGITAL MAPS

The invention relates to a method for consistently updating digital maps (10) on the basis of partitions. To this end, a check is first of all carried out in order to determine whether the update data (11) can be applied to the partition (12). For this purpose, the partition (12) must be at a minimum version level. If this condition has been satisfied, all of the operations involved in the first transaction (13) are carried out in the partition (12). A check is then carried out in order to determine whether the transaction (13) also affects other partitions (14). If this is not the case, the operations are marked as valid changes in the partition (12). If other partitions (14) are affected, a check is carried out in order to determine whether the transaction (12) has already been carried out there. If so, the current partition (12) is erased there from the list (15) of partitions which still need to be processed. Otherwise, the partitions (14) are entered in the current partition (12) as still in need of processing. If partitions in which the transaction (13) still has to be carried out still remain in this case, the operations carried out are marked as not yet being valid in the current partition (12). Otherwise, all operations involved in the transaction (13) may be marked as being valid in all partitions affected. This is repeated for all updating transactions.
