5. ACCURACY ASSESSM ENT 
In order to verify the methodology's applicability, the results 
obtained from automatic lineament detection need to be 
checked. To test the accuracy, two different approaches are 
followed. 
In the first approach rose diagrams for both auttomatically and 
manually extracted maps are created and major orientation of 
the lineaments are compared. 
In order to check the reliability of the results, previous studies in 
the region by Karpuz (1982) and field investigations of Gólbasi 
andesite mines are taken into account. 
In the second approach, the near-face lineaments with the face 
discontinuities are compared. The face discontinuities are 
determined with the same method that is applied to the Ikonos 
imagery. 
For the accuracy assessment, number and the total length of 
lineaments are considered. 
5.1. Directional Analysis 
For the rose diagram applications, the ‘Line Best Fit’ method is 
used. This method uses the direction of a straight line that is 
computed with a least squares approximation of a line element. 
Simple illustration of the method is given in Figure 4.
