A method for encoding and decoding objects with reference to a traffic route network

According to the inventive method for encoding and decoding objects with reference to a road network, the encoded information can also be decoded using data bases that are different from a data base used for the coding. The objects are provided with relationships with at least one relational object, which is available in data bases that are used for decoding. Said relationships are not obtained primarily from the road network. Position data can also be provided with a position type designator which indicates e.g., whether the position that is transmitted is an exact or navigable position or the position of a search area.
