2.2 Web integration 
In the application, the user sends the map parameters over the 
Internet, and the map image is formed according to the setting 
parameters. In Figure 4, the architecture of the application is 
shown.

Figure 4: Architecture of web-based multimedia GIS 
application. 
Map Objects ActiveX software component and Map Objects 
Internet Map Server (MOIMS) software were used in the study. 
Map Objects builds GIS application and MOIMS is a gateway 
program between Web Server and the mapping application 
(Garagon, 2002). These tools were embedded into a Visual 
Basic file. All map layers and functions on the web page were 
added by writing codes in the Visual Basic. Microsoft Internet 
Information Services program was used for information sharing 
over the Internet. Figure 5 shows the application on the Web. 
The web page contains an interactive map container, which 
displays the map layers, a toolbar column, which is used for 
querying buildings, and a legend column, which is an 
explanatory table of the map features. Users can use the map 
interactively by performing GIS functions such as zoom, pan, 
identify, and queries (Duran, 2003).

3. CONCLUSIONS 
An Architectural Information System with the modules and 
special archives provides the possibility for the comprehensive 
documentation of architectural cultural heritage. The pictures 
can be used for the documentation of pending and actual 
damages on buildings and sculptures. The information system 
will help the public to form a view on the development process 
of their urban environment. The awareness for the importance 
of the cultural heritage will be raised. 
3D city models as components of geographic information 
systems provide for the integration of the vast and 
heterogeneous data required in energy use patterns, social
