2.3 System Implementation 
First, a pilot area was selected in Etiler/Istanbul for 
implementation and application the analysis and design 
of the system was completed. Graphic and non -graphic 
data types together with source that has been used in 
application are n Table 1. presented below.

Table 1. Graphic and Non Graphic Data Used in the Application 
2.3.1 Graphic Data Input into the GIS 
Planimetric and cadastral maps in DGN format and UTM 
coordinate system were obtained from the related 
organizations Levels in DGN file were determined and 
transferred into the DXF by using MicroStation software 
In view of the design of database then into the PC/GIS 
software. Since, DGN format isn't accepted by the 
existing GIS software. Therefore, DGN/DXF/ARCINFO 
conversion had to made for graphic data input. 
Other blue copy maps (utility sheets) were digitized by 
using PC/GIS software's digitizing module as polygon, 
line and point feature. All the digitized map sheets from 
the digitizer units were transferred into UTM coordinate 
system and the topology was constructed. After editing, 
topology has been reconstructed and then adjacent 
maps were joined. 
2.3.2 Non -Graphic Data Input into GIS 
Owner registers data (owner file) have been obtained 
from the related organization as a .dbf and the 
connection with the parcels numbers were set up. 
Inhabitant records have been also obtained in .dbf and 
connected to the number of apartment and flat. Other 
non- graphic data of the buildings, like owner or renter, 
type of building, tax and rent values, heating systems, 
number of floors, type and name of the offices and their 
employer's information etc. were surveyed in the field 
and typed. Other non graphic utilities and planning data 
were read from the map sheets and entered to system. 
The symbols, the code tables were determined and 
related with ID numbers to feature attribute table which 
has been created automatically by processing graphic 
data. After that, graphic and their descriptive non 
graphic data (tabular) were joined. The process of the 
GIS database was shown in Figure 1.
