5. CONCLUSIONS 
The data with high degree of accuracy can be obtained via 
remote sensing over vast areas. On the other hand, the 
evaluation of data compiled within geographical information 
system facilitates various spatial analyses. In this way, it is 
possible to determine change over time especially spatial and 
temporal. 
In this study, a monitoring system was designed for the 
determination of the land use and forest cover changes in 
Yeniciftlik watershed by using multi-temporal Landsat images 
and change-rate and change-direction were examined between 
the years of 1974 and 2001. 
KEY 
It has been observed that the accuracy level (86-90%) achieved 
is well above the generally accepted threshold (80%) for such 
works. ABS
