device allows operator 3D digitising of stereo models (Schenk, 
1999). 
PHODIS ST 30 digital photogrammetry software is used for 
generation of stereo model of Fatih Mosque facades. The 
camera calibration parameters of both 80 mm focal length and 
150 mm focal length objectives were defined to the program 
using camera calibration protocols. Inner orientation of images 
was performed manually for transformation of pixel coordinates 
to image coordinates. Sufficient numbers of tie points were 
measured manually for relative orientation of images. Sigma 
naught of relative orientation is better then 8 pm for whole 
stereo models. For absolute orientation measured signalised 
control points and natural points coordinates in local coordinate 
frames were used as control point. The definition of coordinate 
axis of control points was changed because, Y-axis corresponds 
to the Z-axis and Z-axis corresponds to the Y-axis in normal 
case close range photogrammetry. Sigma naught of absolute 
orientation is better then 7 mm for whole stereo models. 
Distribution of control points and tie points for stereo model 1 
in northwest facade of Fatih Mosque is shown in Figure 5.

model 1 in northwest facade 
After generation of stereo models, detailed 3D vector plotting of 
facades were achieved manually by experienced operator. 
MicroStation(Bentley) software was used for 3D vector plotting 
of Fatih Mosque facades as CAD software. The examples of 3D 
vector plotting are shown in Figure 6 and Figure 7. 3D models 
of Fatih Mosque can be generated using digital images and 3D 
vector data. This task is out of this documentation project 
scope. 3D model of Fatih Mosque is also generated for the 
research purposes. Detailed description of this research study 
can be found on Yastikli at al., (2003).

5, CONCLUSION 
Close range photogrammetry has been used successfully for 
documentation of cultural heritage for many years. Digital close 
range photogrammetry is currently an effective system 
providing both vector and raster data type. Operational steps of 
documentation of cultural heritage by using digital close range 
photogrammetry are consisted of geodetic measurement of 
control point and historical monument environment, 
photogrammetric image acquisition and stereo restitution. In 
this paper, operational steps and details of Fatih Mosque 
documentation is presented. Digital close range 
photogrammetry is an effective system for documentation of 
cultural heritage. The products of digital lose range 
photogrammetry can be used for 3D model generation and 
visualisation of cultural heritage.
