The work of documentation of historical places and 
cultural heritages is complex and multi-faceted process 
(Kulur, 2005). Documentation of historical or cultural 
structure covers the entire steps which is necessary for 
determining current state of the structure (shape and 
position) in three-dimensional space that are surveys, 
process, storage and presentation (Georgopoulos and 
Ioannidis, 2004). There are a few techniques for 
documentation of cultural heritages (Bohler and Heinz, 
1999). These techniques which are very important and 
necessary, are traditional surveys, topographic 
techniques, photogrammetric surveys and scanning 
technique (Bohler and Heinz, 1999, Scherer, 2002). 
At this point, it is a huge advantage that photogrammetry 
can provide reliable information in a short time (M. 
Yakar and HM. Yilmaz, 2008). Nowadays, 
reconstruction of building in 3D model is very popular 
due to the developments in digital photogrammetry 
parallel to computer technology (Yakar et al., 2011). 
Today 3D building models become almost indispensable 
for city planning and tourism (Suveg and Vosselman, 
2000). 
In this study, it is aimed to reconstruction the Doger 
Caravansary that is in the city of Afyonkarahisar, in 3D 
model by the techniques of photogrammetry. In the field, 
6 points are established as closed polygon which is 
covered the building. Coordinates of points are calculated 
in local system with surveying and levelling. Photographs 
are captured by using Nikon D7000 camera. 3D model is 
generated in Photomodeler software. 
2. FIELD WORKS 
In field work, local coordinate system is used for points. 
The mosque is covered with 6 points on the polygon. Not 
only Angles and distances are surveyed but also levels 
are determined with levelling. For the detail points of the 
Mosque, the facade photographs of the mosque are used. 
In the selection of detail points, the physical properties of 
the surface and sharp lines are considered. Same detail 
point on the mosque surface is surveyed from different 
polygon points as a control survey. 
Photographs using for 3D model are captured with Nikon 
D7000 with a resolution of 16.1 MP and 18mm lens.it is 
paid attention for every photographs has at least 6 detail 
points on it. For every one of facades, the photographs 
are taken from different angles but photograph for the 
real surface covering are captured approximately 
perpendicular to the surface. 
3. OFFICE WORKS 
Office Works consist of coordinate calculations and 
generating 3D model. Basically all surveyed detail points 
data in the total station is transferred to computer. In 
Netcad software the 3D coordinates of point are 
calculated. in the field work some surveys are made for 
controlling the detail points as same detail point is 
observed from different polygon points. At the result of 
this controls 4 mm differences are detected between both 
vertical surfaces and horizontal surfaces. At the end of all 
696 
calculations and controls, the coordinates of points are 
saved in .txt format. 
Interior orientation parameters of Nikon D7000 camera 
are get from PhotoModeler software and saved as .cam 
format. For absolute orientation the .txt and .cam files are 
used. After orientation processes we are ready for 
drawing. All facades are drawn from photographs which 
have different angles for same facade. Some details on 
the surface are defined from single photographs to 
surface. At the end of the drawing, 3D model is 
consisted. This model is covered with tissue 
automatically but some problems related covering are 
solved by selecting photographs manually. At the final 
stage, the orthophotos and facade drawns import to 
AutoCAD software to producing base plate.
