In methods for encoding and decoding objects with reference to a traffic route
network, wherein the encoded information can also be decoded with the aid of databases
that differ from a database used in the encoding, the objects are provided with
relationships to at least one relational object which is present in databases that
are used for the decoding, and the relationships do not primarily result from the
traffic route network. A position indication can also be provided with a position
type designator, which for instance indicates whether the transmitted position
is an exact or navigable position or is the location of a search space.
