One of the main objectives of this study was visualizing the
photo texture in GIS environment. However, only the texture
parts of the building can be seen in 3D in ArcView. For this
reason photo texture could not be used in a structure
representation aim. It is also possible to make miscellaneous
queries over joined layers (Fig. 4).

5.3. The Graphic and Attribute Databases Integration
We use two different kinds of databases: first one, which
includes in text information, is attribute data and the second
one, which has geometrical information, is graphical data. The
first database is handled with Arcview 3.2, which is a GIS
software by ESRI, and the second database is generated from
the photogrametric digital system (PhotoModeler). Both
databases are linked and managed together by the GIS software
ArcView 3.2, creating the AIS.
To make a relationship between graphic and attribute data,
database knowledge or an attribute data belong to the related
object is needed. For attribute data that should be in the AIS, a
content design has been done and filled in MS Excel in DBF
(Data Base Format) file format. The following table shows the
integration of the graphic and attribute data (Table 1). In this
project, although only 3D texture model has been generated as
graphical data, all the components of the attribute data have
been used. It can be added the other parts of the graphical data.
Besides, in any time the users can update all data.

6. CONCLUSION
In this study, design and application of an architectural
information system has been realized in a simple sense. The
basic components of the system are digital photogrammetry and
GIS. An integration between the 3D model of object generated
from photogrammetric techniques and attribute data concerning
the same model of object has been provided. With this
integration, the data will be continually updated, analyzed and
queried. Aspect of the documentation, registration and
observation of historical objects, two techniques used is nicely
proportioned. The results of the study confirm that the
management and observation of the historical buildings with
proposed AIS was done very easily and effectively.
7. FUTURE LINES
The project designed for AIS as a proto-type will be extended
on the basis of city or country. As mentioned above, one of our
first objectives was to visualize of the 3D photo texture in GIS,
but it was not provided completely. Afterwards, we will focus
on solving this problem and add the project other additional
information.
