We have two kinds of databases: the one who has the graphical
and geometrical data and the one who has the alphanumeric data
related to the graphical data. The first one will be generated
from the photogrametric digital system or from other graphical
external files (like digitized plans, amateur photographs etc.).
The second one will be handled with the DBMS ACCESS. Both
databases will be linked and managed together by the GIS
software Arc View 3.2, creating the information system.
Objects are being built by linking spatial data (point, lines or
polygons that are defined by geometry and topology) with non-
graphic information in GIS. Coverage, also called as layer, is

the basic unit of storage in Arc/Info. In this study Arc/Info has
been used for the establishment of topology of the coverage.
Then the coverage has been imported to ArcView software.
This software has been produced as a vector based GIS but also
it has limited use of raster base data as well. In addition to
several querying and analysis advantage, the result of these
attributes.
Digital data in Dgn format has 25 different layers. These digital
data were transferred into AutoCAD format and number of
these layers reduced in AutoCAD. The main layers used in this
study are shown in figure 2.

Figure 2. Data Structure
Also some of non-topographic information for feature
(attributes) such quarter name, street name, door number,
building functionality, basement, medium floor, roof, total
floor, building condition, registration, building name,
construction date, financer, architecture etc. were stored in the
database table. Afterwards digital terrain model (DTM) of
study area was being produced and captured with orthophoto in
ArcView software. This model is shown figure 3.
3D city modeling allows a person to interactively fly and walk-
through a given urban space. This technology has already been
applied to several cities worldwide; however, it has usually been
implemented for limited sections of the city only. For these
reasons 3D city model of study area was being produced. This
model can be seen Figure 4.
