2.2.1. Building 3D Building Model in ArcView 
The CAD model created in Zeiss SSK software was converted 
to shape file format and transferred into GIS software Arc 
Toolbox to build the topology of buildings and roads. First the 
building heights were defined through their flat numbers then, 
attributes data were added in ArcView 3.2 software. By this 
way, various queries can be done in building layer and 3D 
building model was produced for the visualization. Finally it is 
draped on a TIN surface created from contour lines (Fig7). 
The Figure 8, in the following is also a small example view of 
2D City Information System. Here user can query all the 
buildings and also see the attached image to the relevant 
building.

2.3. Comparisons Between Created 3D City Models 
The 3D city created in the first part in first application by 
photogrammetric software “Photomodeler” is visualised in 
Arcview 3.2. The vector data of the building extracted from 
terrestrial images. Generated 3D building was in original 
position and it was referenced with the cadastre map. Also 
attribute data belong to the building was added to the 3D 
graphical data in 3D scene. The only negative point is that the 
texture parts of the building can not be seen in 3D in ArcView. 
In the second application vector data of the 3D city model is 
extracted at the end of aerial image evaluation with Zeiss SSK 
software. And the visualisation of photo textured model is 
realized in AutoCAD. It is also possible to inquire 3D position 
information. The negative point is the lack of attribute data
