4.4 The Production Of The Silhouette Maps Of The Both 
Sides Of Bosphorus To Control The Silhouette Changes 
The first silhouette maps of the both sides of Bosphorus are 
produced in 1998. To compare the silhouette maps the same 
conditions are followed. Therefore for the new maps the object 
distance is selected as the same of the former maps as 750-1000 
m. The selected objective for this work was a Sonnar 4/150 mm 
and the camera was Rolleiflex 6008 metric. Bosphorus was 
divided into four regions and totally 559 images are taken. 439 
models are formed and using Phodis software three-dimensional 
digitising of the silhouette was performed. 19 triangulation 
points and 41 polygon points are measured at this regions and 
GPS and total stations are used. The new produced maps are 
coincided with the 1998 dated maps and the silhouette changes 
are obtained and digitised.
