Abstract
A method of updating a digital map comprising elements of a traffic route network, in a user end device on which at least one user application of the digital map runs, using a second digital map which is arranged in a control center, in which only a subset of elements of the digital map required for a current user application is updated in close to real time conditions when the elements of the digital map are required by a current user application. Since the user end device can precisely delimit the element subset required for a current user application, only minimum data transmission is required.

16. A method for updating a digital map comprising elements of a traffic route network, in a user end device on which at least one user application of the digital map runs, relative to a second digital map arranged in a control center, comprising the steps of:
-
selecting an element subset of the digital map to be updated at the user end device;
requesting updating of the selected element subset from the control center via an at least temporary data link;
selecting an updated element subset from the second digital map from the control center;
determining whether an additional element subset at the user end device should be updated to maintain the digital map internally consistent after updating of the selected element subset;
selecting the additional element subset from the second digital map if it is determined in the determining step that updating is needed to maintain internal consistency of the digital map; and
transmitting at least one of the selected updated element subset and the updated additional element subset from the control center to the user end device. - View Dependent Claims (18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42)

determining at the user end device after receipt of the updated element subset whether at least one additional element subset of the digital map require updating to maintain the digital map internally consistent;
requesting updating of the at least one additional element subsets; and
transmitting updated additional element subset data from the second digital map from the control center to the user end device. - View Dependent Claims (19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43)
