source data as well as intermediate and end products will 
be reviewed and extended from time to time. 
Photogrammetry is an important approach for data 
acquisition, because of the previously stated advantages, 
which certainly need to be exploited fully in our future data 
acquisition process. Besides advanced data acquisition 
approaches should also be investigated. The suitability of 
space images (e.g. using MOMS data) for our purpose will 
be closely observed in terms of quality and costs, although 
at the moment it is not applicable as long as 1 meter 
resolution data are not available under operational 
circumstances. 
Another task is to maintain, update the existing databases 
and fill them with further details, for instance collection of 
data for towns/cities with less population than 50 000, put 
more traffic relevant attributes like house numbers, 
different kinds of driving restrictions (especially time and 
vehicle-type related ones) and so on. Meanwhile the 
production of navigation CD-ROM's should be brought into 
line with this development of the MultiMap data base. 
Another development is the introduction of the digital traffic 
broadcasting RDS-TMC (radio data system - traffic 
message channel) in Germany and other European 
countries, with which both MultiMap and navigation 
Systems must keep step.
