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.
