castle were restored via expropriation. Some of these assets are 
used as recreation area for public use and the others are used as 
hotel or office by non-governmental organizations. The study 
area extends 600 metres along north-east and 150-200 metres 
along east-west.

6. REALIZED STUDIES 
6.1 Data Collection 
In this study, transforming of historical real estates’ private 
property to public property is aimed. To realize this purpose, 
cadastral map, topographical map (created in 2000), 
development plan and aerial photos (1970) of the area have 
been collected from related institutions. These data were in 
CAD format and so, they haven’t had topological structure. 
Land registry data were in excel format.

Firstly, three dimensional topographical map of the study area 
created. This process realized after the construction of three 
dimensional digital terrain model via contour. Then, castles 
(Figure 4) and existing buildings (Figure 5) overlapped on this 
surface. Thereby, general topographical situation of the study 
area created. Graphical data displayed with ArcView software.
