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.
