The Internet representation at municipality level is realised in a
completely different layout than on the county level (see fig. 3).
This gives the municipalities the chance to have their own
Internet design. On the other hand it allows the communes to
create different Internet services on top of these data sets such
as fingerposts to the administrative offices, for advertisement
and so on. For this a uniform Internet appearance is desirable
within the municipality.

5. SUMMARY AND CONCLUSION
Due to the general availability the Internet technology
increasingly gains in importance also for the official
administrations. The employment of Internet technology
represents here a more profitable solution. The Internet is based
on the client-server architecture. This offers the possibility that
the data remain and can be administered and maintained, where
they are produced due to the competence, the responsibility, the
technical knowledge, and the infrastructure. Additionally also
the programs can remain on the server, so that the user of the
data does not have to worry any longer about complex hardware
and software. The user accesses data only via the WWW-
browser. The information are ready for use. By such an
approach a lot of time can be gained related to training of
programs, maintenance of data and costs of hardware and
software. In contrast to this stands the responsibility, which the
data provider has to guarantee. Taking over the role of a service
provider he has to deliver and publish the data in a easy-to-use
form and based on the requirements the users on county or
municipality level define.
By using Open Source solutions the opportunities for
participation at developments of others exist. The solutions
often fit better to the needs of the users, because users may
themself be developers of system components. Apart from the
smaller capital outlays the high stability and security as well as
the large flexibility of the Open Source code plays an important
role. Therefore Open Source solutions find also increasing
acceptance and a rising spreading degree. From the users
viewpoint no serious distinctions are given here compared to
commercial products. It looks somewhat different on the side of
the provider of an Internet-GIS service such as a cadastral
office on the county or municipality level. Here it is to be
clearly presupposed that technically experienced staff exists,
that does not only guarantees the systems availability in the
given manner, but also develops and expands the system
further. With the appropriate understanding of the role of a geo
chief information manager and a service provider the land
registration offices become able to deliver full geo service
packages from one hand.

7. ACKNOWLEDGEMENTS
The development was partially supported by a financial grant of
the administration of the district Bad Doberan.
We also will credit the achievement of the developer of the
UMN-MapServer as well as to all other developer of the used
OpenSource software components.
