Table 4. Area distributions of land use class for 2001 
The spatial distribution of main land-use classes is provided in 
Tables 1, 2, 3, and 4; land use maps belonging to the years 
1974, 1984, 1994 and 2001 are shown in Figures 2, 3, 4 and 5. 
Images recorded at ten year intervals were compared to 
determine the direction of change. The major change between 
the years of 1974 and 1984 was the planting of coniferous trees 
in place of deciduous trees. Additionally, there was a great 
increase in settlement areas. The increase in coniferous trees 
and settlement areas continued between the years of 1984 and 
1994. In 2001, the areas of settlement have increased and the 
areas of coniferous trees started to decrease, and creating gaps. 
Table 5 and Figure 6 summarize the area change rates and 
direction of change in the study area. 
Accuracy assessment is very important for a better 
understanding of the developed result and use of result making 
decisions. In this study, 50 ground control points were used for 
the accuracy analysis of the classification. Ground truth data 
were obtained from forest maps and tabular data. In the event 
that the ratio of the accuracy of the estimations to be obtained 
through remote sensing is 80% or above, then the classification 
761 
is assumed to be accurate and reliable (Swan and Davis, 1978). 
Ratios of accuracy of the classification for all classes belonging 
to the years 1974, 1984, 1994, 2001 were 89%, 88%, 90% and 
86% respectively.
