Abstract

In a method for encoding objects in a traffic route network, to which information from one transmitter at a time to a receiver is transmitted, and for the encoding and decoding of which different databases, in particular digital maps of the traffic route network, can be used in the transmitter and the receiver, the objects are each provided with at least one coordinate chain, which is located at least in part on traffic routes that are also included in the database of the receiver, and which includes characteristic properties of parts of the traffic route network.
