During the past few years there has been a lot of activity in the exploration of location referencing methods. The problem of location referencing is the critical point for all telematic applications dependent on distributed geographical databases, which is mostly the case. While there is a progress in standardization of methods based on heuristic descriptions like names, classes and single co-ordinates that have to be interpreted according to sets of rules that are more or less complicated, the authors still see a need for clear and universally valid methods that work on every navigation database. The main disadvantage of the heuristic descriptions mentioned above is that only objects represented in both databases involved in the communication can be referenced. The uncertainty is always high because of differences in the underlying co-ordinates and name spaces of the terms. On the other hand systems like fixed TMC reference tables with a lot of maintenance problems regarding up-to-date-ness and completeness are in use. A universal method for geometrically based location referencing is suggested. The usability of the method as a back bone for advanced location referencing including the embedding of not pre-defined objects for different use cases in telematics is shown and demonstrated with results from the current development.
