2. PHOTOGRAMMETRIC EVALUATION 
2..1 Used Photogrammetric System 
In this study, Z/I Imaging Digital Photogrammetric designed by 
Zeiss and Intergraph initiative was used. Photogrammetric 
processes were made by Stereo Softcopy Kits (SSK) include 
ISPM, ISMS, IS, ISDM, ISSD, ISFC, ISBR, I/RAS C. 
Microstation V.8 by Bentley Inc. was used as a CAD tool in 
this study (Z/I Imaging, 2001). 
2.2 Obtaining Aerial Photographs 
Time series aerial photos of study area were obtained from 
General Command of Mapping (HGK) and General Directorate 
of Forestry (OGM) in digital format. These photos were 
produced for different purposes during 1955-2002 periods table 
1, figure 4, 5, 6, 7 and 8.

2.3 Evaluation of the Aerial Images 
Pre-processing phases of the aerial images were made 
according to following instructions, first, image pyramids were 
made by using Many-Files-Converter module that enhance and 
ease image processing then the image is represented in three 
part overview, intermediate and detail. Finally, image 
orientation is made and process is continued. 
To get absolute orientation and superposed to National 
Coordinate System was used. Pre-defined reference points such 
as the old schools, buildings and mosques corners were used to 
get the best result for references. These reference points are 
evaluated and fixed comparatively.

3. DETERMINING THE FORESTRY BOUNDARY 
USING THE AERIAL IMAGES 
Available forested lands and cadastral units were compared 
according to related processes. The format transformation 
between .dgn and .dxf were made and finally the gained data 
was evaluated by using ArcInfo and ArcView softwares. 
3.1 The Analysis of the Forest Property 
The change of the forest presence in study area is given in
